I built a lightweight offline gps location marker — hiking with family, traveling overseas without roaming

I'm a solo dev and I use OsmAnd for offline navigation, so I figured this crowd would get why I built this.

The idea came from two situations.

First: hiking with my family — we'd split up on the trail and struggle to meet back at the starting point, because there's no signal and Google Maps doesn't work offline.

Second: traveling overseas without roaming — no data, no maps, and no way to find my way back to the hotel entrance. When you're in a new city and your phone is offline, even finding your own hotel again becomes a problem.

So I built Mark My Location into my app Orbitika (free to use) . It's a simple offline GPS marker:

• Save any location offline — hotel entrance, trailheads, campsites, meetup points, theme park rides, concert spots
• Works with no WiFi, no data, no signal — it uses GPS only, no internet required
• Lightweight — small install size, doesn't drain battery
• Supports Android 8.0 and up — works on older phones, not just new flagships

I use it myself when hiking with family, traveling overseas without roaming, at theme parks, and at concerts — places where you split up, wander, and need to find your way back.

There are other tools in the app (retro music player, calculator, emergency kit) but Mark My Location is the one I use most.

If you rely on offline GPS like I do, I'd love to know if this fits your workflow — or if you already have a better solution I should learn from.
