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.
I'm not convinced using rust is all that useful for web development. There are already plenty of other mature well optimized solutions for backend web development that includes a lot of security and qol feature ootb.
Yeah, theoretically rust can be faster than ruby/python/node, but it's harder to optimize it enough to get to that point and you will have a much harder time finding devs to work on such a project because the amount of backend devs that have enough rust experience is so small, they're like on the opposite sides of the ven diagram of languages for web developers.
On top of all that, languages which are heavily used for web development often get low level optimizations baked into the frameworks/languages so you can get pretty amazing performance uplifts over time to bring it to the level of lower level languages.
