Osmand - I use this along Google maps, but it's nice to have entire regions downloaded and it shows more information than Google maps, specifically for back country stuff where you need to see every type of trail

Home Assistant

Wireguard - I love that the protocol is lightweight and secure, makes it really easy to access my home network without needing to expose self hosted stuff to the internet

Bitwarden - self hosted with vaultwarden/SQLite, changed my life and it's really easy to share logins with my partner

Immich - self hosted, the first real replacement for Google photos I've found. It has autobackup and it's really easy to share albums.

Kiss Launcher - I like how simple it is. My home screen ends up disorganized anyway so it's honestly just faster to have a recents list and a quick search feature.
