I've been working on a crowdsourced guidebook app and it quickly became popular on the PCT last season. I just added beta support for the AT. You can download the app here:
https://play.google.com/store/apps/d...m.hikerbot.app
The way it works is:
- App has a database of trails, waypoints (on-trail and in-town) and towns.
- You can download everything to your phone, including topo maps. The app works perfectly fine off-line.
- Anybody can add or edit the data (think wiki). You can edit offline too.
- The app shows photos of waypoints, and hikers can add current reports for things like water sources. You can also easily confirm other people's reports as accurate.
- You can see a feed of edits other people are making.
- The app already contains thousands of waypoints and hundreds of photos, and this will grow quickly.
Let me know what you think! The app is free - I'm just trying to build something useful.
(iOS version is not available yet but will be soon).
