Chat Apps

November 2023 Meeting Topic

Text messaging of various types has become very popular since the beginning of mobile phones. The popularity of chat apps has really taken off with additional features such as group chat, photos, and audio and video chat.

The line between Chat Apps and social media such as Twitter (X), has become blurred as more features are added.

Popular Chat Apps

  • Messages/FaceTime (Apple)
  • Signal
  • WeChat
  • WhatsApp Messenger
  • Telegram
  • Messenger (Meta/Facebook)
  • Google Chat

Why Choose A Particular App?

Convenience: Messages is built into your Apple products. It’s easy to use. There may be no reason to change, especially if your friends use Apple devices also.

Security and Privacy: Signal is your best choice for absolute security, with end-to-end encryption, a security-focused company, and publicly reviewed code. Apple’s Messages is also very secure, but perhaps less so against governments. The Signal protocol has also been adopted by WhatsApp and Google Messages (on Android).

International Travel: WhatsApp is popular overseas and with travelers. You can use WhatsApp with an international data plan. Since it does not use conventional SMS text messaging, you won’t get charged for the texts. WeChat is nearly universal in China and the far east. It is widely used for checkout and payments as well as messaging. Telegram is popular in India, Asia, Africa and parts of Europe.

Features

  • Group Chat
  • Audio/Video Chat
  • Broadcast to large group
  • Stickers, emojis, reactions
  • File Transfer
  • Document Sharing/Team Collaboration
  • Send money

Under the Hood

The original text messaging protocol was SMS (Simple Messaging System). You’re probably still using SMS if you exchange messages with non-iPhone users (probably Android). SMS has a 160 character limit for each message. MMS (Multimedia Messaging Service) is an extension of SMS which allows “texting” of photos and videos (Low-resolution). SMS and MMS messages count as “text messaging” on your cellular plan, and do not use your data plan.

RCS (Rich Communication Services) is a more modern protocol widely used on Android phones. Apple has announced that its Messages App will be compatible with RCS beginning sometime in 2024. RCS messages use cellular data (or WiFi) (not “texts”). However, none of the chat App protocols will probably make a significant dent in your cellular data usage. When RCS is available in Messages, Apple users and their Android friends will see an improvement in the quality of photos and videos sent and received.

The other Chat Apps are each using their own protocols to exchange messages using Internet data over cellular or WiFi. The quantity of data used is probably insignificant.

Send Your Location via Satellite with Find My

I had a chance to try out the new feature of the Find My app that lets you send your location via Satellite. This is perhaps not so easy to demonstrate, since it requires you to be at a location without WiFi or cell service. I was traveling in some areas of North Carolina without cell coverage, so I took advantage of that to try out this new feature.

Prerequisites

  • iPhone 14 or 14 Pro (or later, presumably)
  • iOS 16.1 or later
  • Friend(s) previously added to “Share my Location” in Find My
  • Be away from cell and WiFi coverage
  • Be outdoors with a clear view of the sky

Sharing your location via Satellite in Find My doesn’t send your location to anyone in particular. It just makes your location available so that friends who already have access to your location can access it. It never asked me who I wanted to send it to. Sending your location is a one-way transmission. You do not receive anyone else’s location, or any other data, except a confirmation that your location was sent.

You start off by pressing Me at the bottom of the Find My app.

You will then see an option to Send My Location under My Location via Satellite.

In Progress. Note Satellite tracking icon at top.

Note the little green satellite tracking icon at the top.

Tapping the tracking icon brought up this screen. You turn to face left and right to keep the white dot centered in the green arc. The iPhone acquired the satellite and sent my location quickly and easily. It seemed like it would have worked without me doing anything special to aim my phone.

I hope this little preview gives you some idea of what to expect if you ever need to send your location via satellite. The most important thing is that you must set up sharing your location with friend(s) in the Find My app before leaving on your trip to a remote location.

Cables Galore: Charging and More

90% of all Problems are Cables”

MacMAD Meeting Topic Oct. 18, 2022

Cables are the unwanted stepchildren of our digital lives. More things are becoming wireless, but, we can’t get away from cables entirely. There are a bewildering variety of cable types, which are ever-changing. I’m sure many of you have a box of obsolete Apple cables like this one:

Rat’s nest of obsolete white cables

USB – Universal Serial Bus

USB (Universal Serial Bus) is probably the most-used cable and interface type you will come across. The secret to understanding USB naming is that, generally, USB numbers have to do with speed, but USB letters tell you the connector type. So, USB 3 is faster than USB 2, which is faster than USB 1.

The ABCs of USB

The Familiar USB A Plugs and Jacks – Blue Indicates USB 3 Compatibility

If you bought an iPhone in the last 10 years, it came with a lightning connector, and a lightning-to-USB cable. These were USB A cables for older iPhones, and USB C since (about iPhone 11?).

USB B was mostly for Printers – Rarely Used Now

USB B Jack and Plug for Printers

USB C is the Most Common Connector for New Devices

An Apple USB C to Lightning Cable

USB C has two popular features: The connector is very compact, and the connector is symmetrical, meaning that it will connect in either orientation. The USB C connector also carries the high-speed Thunderbolt hardware interface which used to require a separate cable and connector. Thunderbolt is used primarily for display devices and high-speed mass storage. The complex USB and Thunderbolt standards appear to be merging such that USB 4 is the same protocol as Thunderbolt 3.

The 1,2,3s of USB Speed

USB Speeds Increase Dramatically with Recent Versions

Choose Your Power

Recent iPhones and iPads may not have come with a power adapter, so it is up to you to make sure you have an appropriate one. Apple currently sells a bewildering variety of power adapters. Considering only the USB power adapters, there are are adapters with power ratings of 5W, 12W, 20W, 30W, 35W (dual), 67W, 96W, and 140 Watts. These are all USB-C, except for the older 5 and 12 Watt models. These are all for household plug-in use and do not include adapters for use in the car. A similar range of compatible adapters are also available from other companies.

Your device will not be harmed by a higher-wattage adapter. It will only draw the amount of current it actually needs. If you connect your device to a lower powered adapter, it may charge slowly, or not at all. If you connect your device to a higher powered adapter, it will charge faster, up to the device’s maximum charge rate.

USB is a complex standard which includes multiple data and multiple power standards within the one USB name.

You may “know” that USB provides 5 volt power. However, for adapters providing more than 15 Watts, USB adjusts to 20 Volts. For power above 100 Watts, USB uses 48 Volts. This is all while maintaining compatibility with older 5 Volt devices.

If you still have the power adapter from a phone you got 10 years ago, even if it is “perfectly good”, it is probably not sufficient for your newer devices.

Recommended Power Estimates

Use an Adapter Appropriate to Your Device
Apple Brand USB Chargers 5 Watts, 18 Watts and 30 Watts

Which MagSafe Do You Mean?

Incompatible MagSafe 3 and MagSafe 2 Power Connectors (MagSafe 1 not shown)

Apple has had five different, incompatible things all called MagSafe: three cable types and two wireless chargers.

MagSafe and Qi Wireless Charging Pucks (Notice they all have wires)

Don’t Let Junky Power Damage Your Device

Flea Market Bargain Bin Chargers

Choose reputable cables and power adapters. Apple offers the “MFi” (Made for iPhone/iPad) certification to other vendors. These products have been tested and are up to standards.

Not all cables that look alike work alike. Older or cheaper cables may work with low power devices, but may perform poorly or not at all for higher power modern devices.

Reputable brands include, in alphabetical order: Ainope, Anker, Amazon Basics, Apple, Belkin and MonoPrice. Look for emphasis on safety and clean power. Look for “MFi”. Look for USB C and USB 3.x compatibility. Beware cheap deals that come in a six-pack.

Having Problems? Clean Your Lightning Port

Beware of Heat

Your device may get hot when charging. Keep it out of the direct sun, especially on your car dashboard. In the car, positioning your phone in front of an air conditioning vent can keep it cool. A hot battery may charge more slowly, if at all.

iPhone Overheating Warning Screen

Fire Safety

Don’t charge your device on the bed or upholstery, especially overnight.

Throw away old, frayed, melted or intermittent cords.

Throw away power adapters that have overheated.

Charging in the Car

Modern cars probably have USB ports for charging and for Car Play or for playing audio. Cars tend to lag behind in technology. Many still have USB A ports. It pays to check your owner’s manual to find out which USB ports in your car will charge more quickly. My Honda has low-powered ports in the front, and higher-powered (12.5 Watt) ports behind the center console. Devices can charge twice as fast plugged into those ports.

Most cars have a 12 V accessory outlet somewhere (aka, the old cigarette lighter outlet). These can supply plenty of power. You can find modern adapters to get the USB power you need from these. They are much cheaper than a new car!

The World is Moving Toward USB C

But, USB A will be around for a long while. You should get yourself some USB A to C adapters ( both directions) to make the transition easier. They are cheap.

The Best of the App Store

This post is part of the MacMAD presentation meeting for Tuesday, March 15, 2022. See also iPhone Super Powers.

The Best of the App Store for iOS

Many iOS/iPadOS Apps are free. Most Apps that are not free are less than $3.00. Some are more expensive, or have in-App purchases or subscriptions.

Many people consider that one of the best decisions made by Apple was to allow 3rd party apps on the iPhone. It’s hard to believe that when the iPhone was introduced in 2007, Apple wasn’t initially sure Apps would be supported. The App Store was only introduced in 2008.

There are now about 2 million Apps in the iOS App store. Because it is so easy to buy and install Apps, even the most technophobic of iPhone users have typically installed several favorite Apps. Many iPhone users have so many Apps installed that they have trouble keeping track of them all.

You Must Setup a Credit Card

Because it is a store, and you might buy things, you need to setup a credit card under

Settings ->Apple ID

Once you have done this, you are ready to shop for Apps.

There are three categories of Apps with different information in the “Price” button.

Apps can have a price, or the word “GET”, or a cloud download symbol.

In the App Store, you will see some apps with the word GET instead of a price. Those apps are free. If you see In-App Purchases, then there are aspects of the App you will be asked to pay for later, while using the App.

If you see the cloud download symbol, that means that you already own that App, but it is not currently installed on your device. Maybe you bought or downloaded it on a different device, or maybe you previously had it installed but deleted it. In any case, you can click the icon to download it now for free.

In the figure above, you will see how to spot a reputable app. An App with the Editor’s Choice notation is highly recommended. An App that has hundreds of thousands or millions of downloads and four or five stars is also a very reputable App. Be a bit suspicious if an App only has a small number of downloads, or is “Too new to rate”, or has a low star rating.

Check the Developer/Seller’s Name

If you are expecting the App to be something specific, make sure that the Seller and Copyright fields are what you are expecting. Some Apps have similar names or icons to other, more popular Apps.

Popular App Categories

  • Social Media
  • Games
  • Shopping
  • Audio, Video and Books
  • Travel and Navigation
  • Office Apps – Microsoft ‘s Office, Apple’s Apps

Consider Getting Apps for…

  • Favorite Stores & Restaurants
  • Local News, Weather and Information
  • Your Car and Home

Some car brands have their own apps. For your home, some devices such as locks, cameras and energy monitors have their own Apps. Of course, there is also Apple’s own Home App for all your HomeKit devices.

Some Favorite Apps

  • Next Spaceflight – Always know the next rocket launch
  • Mactracker – Guide to the many versions of Apple hardware
  • AnyList – Handy Family Shopping Lists and Checklists. iOS and Mac

Password Managers

I recommend you use some sort of password manager. Apple’s built-in Keychain feature is improving, but if that isn’t good enough for you, try these. No particular order:

Books and Reading

  • Apple Books – Apple’s own, pre-installed Book reader and Store
  • Libby, by Overdrive – Free eBooks from Brevard Libraries
  • Audible – Purchased and Subscription Audio Books, High Quality

iPhone Super Powers

A day of acquaintance,
And then the longer span of custom.
But first —
The hour of astonishment.

– Bill Atkinson, c. 1987

This post is from MacMAD’s presentation meeting for Tuesday, March 15, 2022. See also The Best of the App Store.

These are some capabilities of the iPhone that typically make people’s jaw drop in amazement and say “It does what?” the first time they hear of them.

Your iPhone Receives Signals from Russian Satellites

It also receives signals from US military satellites, and those of the European Space Agency, and Japanese and Chinese governments. These are all part of the navigation features usually lumped together as “GPS”.

  • GPS – United States Global Positioning System, originally military only
  • GLONASS – Russian Navigation Satellites
  • Galileo – European Space Agency Global Navigation System
  • QZSS – Japanese Satellite Positioning System
  • BeiDou – Chinese Navigation Satellite System

iPhone uses all these systems as required to determine your position as quickly and precisely as possible.

What is that thing?

Your iPhone / iPad can often answer questions of the “What is that thing?” variety. Sometimes an App is required, and sometimes you already have what you need.

What is that Airplane?

“Hey Siri, What Airplanes are overhead?”

The response comes back in tabular form from Wolfram Alpha, listing nearby flights and their positions in the sky.

List of nearby aircraft in flight

Siri automatically invoked Wolfram Alpha in this instance, but Wolfram Alpha is a website which can answer many types of questions. It is primarily oriented towards mathematics and engineering, but can respond to a fantastic variety of queries about factual information. There is also the Wolfram Alpha App ($2.99 + extras), and the free Wolfram Alpha Viewer App.

What is that Song?

“Hey, Siri, What Song is Playing?”

Siri can identify a song playing on your device, or a song playing nearby from another source. For music in the room, Siri invokes Shazam. Or, you can Shazam a song from the control center. Or, you can use the dedicated Shazam App.

Song identified as “You’re Still on My Mind” by The Byrds

What is That Plant or Animal?

You can identify plants and animals with the free Seek App. Seek is from iNaturalist. There is also an iNaturalist web site and iNaturalist App, where you can submit your observations to a crowd-sourced body of observations, where the species will be confirmed or identified by other human observers.

Seek uses artificial intelligence to quickly identify a plant or animal through your camera. You don’t even need to take a photo to get the ID — just viewing the specimen through Seek will produce a likely identification.

What Bird is Making that Sound?

The free Merlin Bird ID app from Cornell Labs can identify many bird species from their songs or calls. You can record the bird call from right within the app. You can then select a part of the recording that is the bird you want, free of background sounds. The App will then suggest a species. This is basically Shazam for birds.

Which iPhone Should I Buy?

Variations of this question are some of the most common questions we get here at MacMAD. “What Mac should I buy?”, “Which iPad is the best?”, etc.

There is a great new site for this called Apple Buying Advice. It’s one of those sites that does one thing and does it well. I hope it withstands the test of time and avoids the temptations of click-bait headlines and over-complicated analysis. Right now, it is very simple and straight forward. Try it!

Use iPhone as Web Cam with Detail

I have a MacMini which has no built-in camera. During the pandemic, I have been doing more on-line teleconferencing (mostly Zoom and Facetime meetings). I have used various cameras and various software to connect them to my computer.

I recently came across Detail, from Detail.co . This application allows you to use your iPhone or iPad as a web camera for your Mac. This is the best solution I have seen yet, and the iPhone has a good-quality camera, so my video looks good.

The Mac application does much more than that, which is both an advantage and disadvantage. It is a disadvantage in that it makes it harder to learn to use. There is a video tutorial on the site. The quick summary is to download the Detail app from the iOS or iPad OS App store on your iPhone or iPad, and also download the app for Macintosh from the web site. The app can work wirelessly, or via a USB cable (recommended).

You may want a tripod adapter for your phone. I bought this one and it seems like a good one. You might want to use that with a small desktop tripod like this, if you don’t have one.

Detail is not free, and they are kind of cagey about the price. I actually don’t know how much or how often they charge. There is a 14 day free trial period. I discovered and got access to Detail through my Setapp subscription, which is excellent for just-in-time discovery of useful, curated apps.

iPhone Pricing 2021

Here is an overview of iPhone prices. These are the prices from Apple’s on-line store in June, 2021. There are 13 different models available as new and refurbished. Apple’s refurbished products are excellent, and usually can’t be distinguished from new.

All prices are subject to change, and availability of any specific model on the refurb store, especially, can change from day to day.

At this writing, there were 13 different iPhone models ranging from a refurbished $339 iPhone 8, up to a brand new iPhone 12 Pro Max, with 512 GB at $1399.

In the chart, the blue bars indicate the price of the base model and the green bars the price of the same model with the maximum amount of storage. There is often an intermediate model between those two.

Apple has probably never had so many different models of iPhone available simultaneously before. Choice is good.

March Meeting Notes

In our March virtual meeting, we talked about Continuity Camera and on-line user guides for Apple devices.

With Continuity Camera, you can use your iPhone to scan documents directly into apps on your Macintosh. It is particularly useful in Mail, Notes and Preview. If you scan paper documents into Notes in this way, they become searchable in the Notes app.

The answers to many questions about your device are contained in the user guide for your particular device, e.g. iPhone, iMac, or iPad. Apple has the user’s guides online. Apple doesn’t keep the user’s guides for older versions handy, so if you are planning to keep a device into vintage or obsolete status, download the applicable user guide before it goes out of date.

I will give you some links, but they are likely to go out of date. The consistent way to find the user’s guides is:

  1. Open https://support.apple.com/
  2. Click on your device at the top
  3. Scroll down. Near the bottom of the page, you will see something similar to this. Click on the User Guide link.
