- Audile: offline, trackerless music recognition.
- Keepassdx + Heliboard: both excellent apps in their own right that create a smoother experience of mundane phone use, but they also integrate rather well together and Heliboard will often pop Keepassdx in to its suggestion bar when you enter a log in page. It's been really nice for me.
- FUTO voice input: speech to text for those who don't want to use Google speech services. Frankly, the FUTO app works better than googles app anyways, it always handles grammar correctly as long as you speak relatively clearly, and integrates with Heliboard nicely.
- Tailscale: for those who need VPN access to their other devices.
- Thunder : a Lemmy client with compatibility with Lemmy's recent server side changes and also has a decent UI/UX tasks.org: fantastic, customizable to do app with various syncing options. Magic Earth: privacy respecting maps/directions for those who don't want google maps.
- Myne: e-book downloader.
- Markdownr: convert webpages to markdown. Great option for mobile, if I'm on desktop I use the Joplin web clipper plug in for Firefox.
Seconding Newpipe, excellent app.
