Captio by boonbits. It sends email using the user's own SMTP credentials. It's been way more useful than the $0.99 I paid.

DarkSky

The Apple weather app is janky, slow, and doesn’t do the one thing Dark Sky did well (is it going to rain in the next hour)

I want an app on Android to record phone conversations as MP3 files in the background. My old OnePlus 3 dialer used to handle this perfectly, not anymore.

Unfortunately it seems the Android APIs are getting locked down for this kind of usage.

If the IP is not the app, yes many. - Regional content (foreign language books) - DJI Fly - Uber in some particular locations - Phone hardware camera (iPhone, Google pixel, etc.)

CodeNavigator for iOS was a great app for cloning repos and reading the code offline. It had support for bookmarking and making annotations as well as syntax highlighting for many different languages.

DigiKam is a very poor substitute.

Barrier KVM, I have been on x11 forever because of this app. Wayland is still fumbling around with copy and paste ill be on x11 for the next decade.

The Timely clock app. It was bought by Google and then never updated so it doesn't work on newer Android versions. Sad.

anki + ankidroid maybe? UI feels old but I haven't found anything else that just works for my spaced repetition needs.

Evernote.

I’m migrating to Simplenote, but it has much much less features.
