I haven’t gotten around to setting it up myself yet, but I have immich-public-proxy pinned. Could solve exactly your problem. Keep your main immich behind your vpn but expose some public galleries of your choosing.

I hadn’t heard of opennutritracker before but it seems cool. Cleanslate is also good, and you can even self host it (although tbf I haven’t tried). Seems like people are working on the calorie tracking side of things!

Organic Map’s voice turning instructions were just recently updated to include the street name (at least in the iOS TestFlight, not sure if it’s in the official release yet). This was something that was preventing me from fully switching over but since this change it is much more usable imo

Unless you’re setting it up for a business, the free tier should be enough. They have options for both self-hosting and hosted versions

Zulip is pretty nice
