@dewey looks interesting! I'm a Swarm user since many years and always wanted a selfhosted, #OSM based alternative. It's life logging for me. I like the return of badges. Wondering how an Foursquare import would match the OSM POIs...

@pr3d I was actually surprised how well the matching worked. I've only had to manually review ~15 uncertain matches out of 2000 or so. The name + coordinates work really well with some naive implementation of text similarity. I can't say if 100% are correctly matched, but so far it seems like it.

@jj_3 Thanks for checking it out, there's no links yet besides the blog post. I'm still working on it. I'll post updates on the blog or here if I have something public to share.

@dewey i am interested! have a look at altstore, maybe you can publish it over there instead of testflight/app store? i deleted my 4sq acc in 2020 and only used the app again in 2025 for a short period of time, but i'm looking forward to a nice and simple alternative. bonus points if i could find my check-in-archive and then import it to a new app 🤤

@pzumk Good idea, I'll take a look at that soon. My next priority is to open source the code for backend + swift app so others can take a look or improve it.

I'd probably make the "instance" configurable in the iOS app so people can just self-host the backend.
