hiker. records your hike, tags what you find, and cuts a cinematic recap of the mountain — GPS, elevation, and a real texture-mapped 3D terrain, all bundled to the device before you lose reception. No signal required until you're ready to share.
Free · Android · built and field-tested on Gunung Gede–Pangrango
Real device screenshot. Native Kotlin/OpenGL renderer, true per-pixel satellite texture — rendered on-device, fully offline.
Ink-dark, media-first, glass over photos and recaps — the part of hiker. you open on the couch, planning the next trip or reliving the last one.
Flat paper, no blur, no gradients — every GPU cycle and every photon saved for a battery that has to last the whole climb, in direct sun.
GPS logs the whole route with the screen off. Elevation, satellite imagery, and trail vectors for the region are already on the device — nothing to download mid-hike, nothing lost if the OS kills the app.
Photos and clips are pinned to the exact point on the trail. Tag a shot as a viewpoint, a landmark, a hazard, or something that needs fixing — real trail intelligence, not just a pretty feed.
The moment you finish, your GPS track, elevation profile, and photos are auto-cut into a short film — 3D terrain flyover, music, real stats — the kind of edit other apps charge a subscription for.
Share the recap and captures to the community feed — liked and commented on like any social app — or leave them private. Either way, the hazard and viewpoint tags stay visible on the map for the next hiker.
The 3D terrain is a hand-written Kotlin/OpenGL renderer with real per-pixel satellite texture mapping — not a third-party map SDK. Same visual bar as Google Earth or Strava's flyover, built in-house.
Hike mode never requests a network tile — a hard rule in the codebase, not a fallback. Recording survives the screen turning off and the OS killing the app mid-hike.
Hazards, viewpoints, and fix-needed reports are visible to everyone by default — the app is useful even to someone who never posts a single photo.
Tuned and field-tested on budget, 32-bit Android Go hardware — not just the newest flagship — because that's what shows up on the trail.
Sideloaded APK for now — this is a proof-of-concept build, not a Play Store release yet. Pick the ABI that matches your device.
hiker. doesn't charge hikers to use it. The feed is the commercial surface — the same place a friend's recap or a trail hazard report already shows up.
Placed like any other post — boots, jackets, poles, packs — surfaced by what someone actually does in the app: which trail, which season, how far they hike. Not a banner bolted on top.
Purchase without leaving hiker., or redirect straight to the advertiser's own storefront — whichever a partner's existing setup prefers. Both paths stay open.
This is an MVP — a working, field-tested proof of concept covering one region (Gede–Pangrango, Indonesia), not a finished business. The recording, offline terrain, capture/tagging, recap, and social layer are all built and running on real devices; the monetization above is the validated next step, not yet switched on. If that's an interesting stage to get involved at, we'd like to talk.
