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.

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.

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.

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.

Self Help: How to Find a Lost File

You had an important file, but now you can’t find it anywhere. In this article, we’ll look at tips for finding that lost file. First, for MacOS, and then for iOS/iPadOS.

Finding a file on MacOS

Searching with Spotlight

You might be tempted to search with Spotlight (the magnifying glass icon in your menu bar). Spotlight might find your file, but by default, it returns a lot of results other than files and folders. You might not be able to see the tree for the forest in your Spotlight results. If you visit Spotlight in System Preferences, you will see that Spotlight returns results in up to 20 selectable categories, many of which are not relevant. For instance if you had a file related to a jacket in size 42 long, you might search with Spotlight for 42L. Spotlight will unhelpfully inform you that 42L = 1.48 cubic feet.

Finder Search

You can perform a search in any Finder window by clicking the magnifying glass icon in the upper right of the window, and typing your search term. This is different than Spotlight, and it searches only files.

Beginning a Finder Search for 42L

In the example above, you have typed “42L”. You will see that it has found two files, neither of which actually have 42L in the filename. However, there are two clickable options here that you should consider. If you click the dimmed word Filenames, the search is restricted to only filenames. Otherwise it will find any file that contains the search term. To start with, the search only includes the folder you happened to start in. In this case, that is the Documents folder. If you click “This Mac”, then it will expand the search to your entire computer.

Also, if you click the + to the right side, next to Save, you will get the option to further restrict your search by Kind, Last Opened Date, Last Modified Date, and a great many other attributes. For example, you could select documents whose Kind is Image. That would find only photographs or drawings.

Searching This Mac for all Image files.

By clicking the column headers in the Finder you can sort by Name, Size, Kind, Date Last Opened, etc. This can help bring likely files to the top. Consider searching by Kind, Date, Size, etc., without using a search term. You may have forgotten what the file was named exactly, or it may have been accidentally renamed. By doing this, you may find a file whose name was mangled somehow. If the file is fairly recent, it pays to look at the Recents icon in the Finder sidebar. Maybe you will recognize your file in that list. Again, you might want to sort the list.

Don’t forget to check the Trash. Files in Trash should show up when searching This Mac, but it’s worth a look.

Check the Desktop. Don’t just look at your desktop on the screen. MacOS has a feature called Stacks, which tends to hide things on your desktop. You either need to expand each of those stacks by clicking on them, or else open a Finder window, and visit your Desktop folder directly.

Plan B: Other Places to Search

Maybe the file isn’t actually on your computer, but it exists somewhere else. For example, a lot of Apps like to save files on Cloud Storage of some kind. Here are some ideas of places to look:

  • iCloud Drive
  • Microsoft OneDrive
  • Google Drive
  • Evernote
  • Dropbox
  • Network-Attached-Storage (NAS)
  • USB Stick/Flash Drive
  • Your other computer or phone or tablet
  • Camera Memory Cards
  • Virtual Machines (files in a Virtual Machine won’t be found when searching outside that machine.)

The cloud storage services are often mirrored to your local system, but not always. So, you may need to sign into their web interface and browse the files there.

Plan C: Files in Transit

Think about where your file originated in the first place. Most of the files on your computer, you didn’t create. They came from somewhere else. If someone sent you that file, it may still be available. If it’s not too embarrassing, you can always ask the sender to send it to you again. Otherwise, check your messaging apps and services:

  • e-Mail Inbox(es)
  • Apple Messages App
  • Facebook Messages
  • What’s App
  • Hangouts
  • We Chat
  • Signal

The file may still be in the message by which it originally arrived. If you originally downloaded the file from the internet, it’s probably easiest to just find it again with Google and re-download it.

If you created the file locally, did you ever send it to anyone else? If so, a copy of the file may exist in your outbox on one of the above services. Or, you can ask a recipient to send you back a copy.

Searching for a lost email is another topic in itself to be covered in a later post.

Plan D: Recover from Backup

Maybe the lost file used to be on your computer, but it was accidentally deleted. This is the scenario where backups come in handy, especially Time Machine backups. You have been performing regular backups, right?? Well, even if you haven’t, there is a good chance that Time Machine has saved your bacon. By default, Time Machine keeps some backup versions of files on your local computer even if you have never performed a Time Machine backup to an external drive (like you should!).

To recover files from Time Machine, it helps if you have some idea where in your file system the file was located. If you’re not sure, you can start with the usual suspects like the Documents folder, the Desktop or the Downloads folder. Open that folder now, in the Finder. Attach your Time Machine backup drive if you have one. Make sure that your folder of interest is the active Finder Window.

Click the Time Machine icon in the menu bar (it looks like a clock). Select Enter Time Machine. This will open sort of a time-tunnel view of that particular Finder window.

You can navigate back to some older version(s) of that folder and look for your file. If you haven’t backed up to an external drive, there may be very few snapshots available for viewing.

Finding a File on iOS or iPadOS

The key place to look for files on iOS is the Files App. It has a blue folder icon. Like MacOS, it has a Recents view which can be helpful. It can show files stored directly on your device as well as files stored on iCloud Drive. You may also have various other cloud services folders under Files. There are also the Shared, Recently Deleted (Trash), and Downloads folders. These are all worth checking.

In iOS or iPadOS, you can search for a file by swiping down from the center of the home screen. This will bring a search text box onto the screen as well as an on-screen keyboard. You can then search by typing or by voice.

I hope you were able to find your lost file, or at least to find some hints useful for next time.

Controlling Your Device with Gestures

These are the Keynote slides from MacMAD’s February 2020 (updated 2022) meeting on using Gestures on iOS and Macintosh. Note: this presentation contains some short videos so is rather large (~160 MB). The link is to a Keynote presentation file shared in iCloud.

How to Upload Images Right-Side-Up

A frequently asked question on the Internet is:

“My photo appears correct on my computer, but when I uploaded it to [website], it is sideways. How can I make my image upload in the correct orientation?”

This problem is surprisingly universal, it affects many different web sites and users of Windows, Macintosh, tablets and smartphones are all affected. It most often affects photos that were taken in portrait orientation.

Local Image Correct Orientation
Uploaded Image Sideways

The problem is caused by the varying interpretations of the image rotation tags in the EXIF data accompanying digital photos. This problem is not likely to go away anytime soon because the meaning of the rotation tags is somewhat ambiguous, and there is disagreement about what the correct way to handle them ought to be. Some software thinks it should apply the tags, other programs or sites think they should ignore the tags or remove the tags.

There is an easy solution for users: Edit the photo in your photo editor of choice (with the possible exception of Windows Picture Viewer). Rotate it to be right-side-up if necessary. Then make some other change that affects the image. Tweak the contrast or the color. Crop the image slightly. Almost any change will work. Then, save it.

The saved image will have its pixels oriented properly and have no Orientation tag, or have the default Horizontal tag. Everybody agrees on how to display an image like that. When you upload it, it will display the same as you saw it on your computer.

If you edit an image, but only rotate it, your editor will probably just change the Orientation tag without changing the image pixels. Unfortunately, not every program or site will interpret the Orientation tag the same way as your image editor.

If you make a change to the actual image, it forces the program to completely re-write the image from scratch, which results in an image with the default orientation.
