Get in touchBuilt by one developer, tested on real trails.
Longdog Apps Inc. is an independent studio building focused, native software for Apple platforms. Every feature starts as something actually needed on a hike — GPS accuracy in the backcountry, elevation data that means something, and a watch app that keeps up when a phone can't. No shortcuts, no tracking SDKs, no dark patterns — just software built the way a hiking app should be built.
