Hi HN! This is a trail companion web app (think AllTrails) I hacked together in a couple weeks time. I was inspired to create this project while training for an extended backpacking trip. My motivation was to create a UI tailored exactly to my liking, and to be able to track my progress along the trail without draining my battery. I also wanted to experiment with PWA technologies. I successfully used it on my five day adventure along the Knobstone Trail in southern Indiana, and even though it's web-based it hardly consumed any battery life on my old first-gen Pixel XL. It's set up currently…

Hey HN, I built MBCompass, a lightweight, privacy-friendly compass app for Android. It works fully offline, doesn’t ask for unnecessary permissions (no GPS, no internet), and is open source. Most compass apps out there are bloated or ad-heavy. I wanted something clean, fast, and featurish. So I made this! It’s only ~1.7 in size and uses a low-pass filter to smooth sensor readings. I’d love feedback or thoughts – especially from others building simple, privacy-first apps! https://f-droid.org/packages/com.mubarak.mbcompass/…

Dear HN, My wife and I both love nature and have always wanted a Pokémon go style app, to collect and learn about different species we find. All the usual species identifying apps were didn’t feel fun enough, so we designed and built one together! Would love for you guys to give it a try and share any thoughts you have.

I've recently been working with real-time geoJSON data at a rate of 50+ queries per second. SaaS solutions can be prohibitively expensive at this rate, thus, I created go-reverse-geo. Data is pulled from geonames.org and is stored in MongoDB (a requirement of my current project). It is very much a work-in-progress (I wrote it this morning). Hope someone finds it useful. https://paranoia.dev/vivi/go-reverse-geo
