Android:
- Nexdns.io^1 - Open source DNS provider with DNSSEC and over TLS. Then can also block ads at the DNS level. I don't actually use the app, I apply it at the system level with the "private DNS" settings.
- Bitwarden^2 - Open Source password manager with Yubikey auth and stores TOTP.
- Imagepipe^3 - Quickly and easily strip exif data from image (open source too).
- Markor^4 - Used to make local notes of things I don't want shared over a cloud or google connection. Just a .md note.
- Wireguard^5 - Have my own VPN setup for when i'm on public wifi, also allows me to access my server/applications remotely.
- URLCheck^6 - This app is fantastic, intercepts links to remove tracking parameters, unshorten them or even scan them with a virustotal API. I also use it to redirect twitter to nitter or apply a paywall remover.
