Especially for those of us with no coding background, who can’t just build/edit an app.
For example, I like using Gadgetbridge to replace my fitness tracker app: https://gadgetbridge.org/
It’s not nearly as full-featured as a regular fitness app, but it literally can’t connect to the internet so there’s no way anyone can get my health info.
Forest is a simple step counter that shows you the steps you did today, with a little extra info.
Doable is a tasks/reminders app. It’s not the most feature rich, and notifications are only in beta, but I love the design and it does what I need well.
Data Monitor shows you how much data you’ve used in your current plan, and you can see which apps use the most data (or wifi).
Quillpad for notes.
LibreOffice Viewer lets you open word documents and the like.
Squawker lets you open Twitter links more privately, and even follow users to see all of their posts, but requires you log in with an account.
Breezy Weather is a really nice weather app.
Love seeing Forest get the love it deserves. Beautiful UI.
