TrailSplits on your phone
Plan a trip on the website, then take it outside: the map, the route and each day's GPX on your phone, and offline once you have downloaded it. No app store, no sign-up.
Open a trip or route you were sent
Paste the link. TrailSplits checks it, shows the trip's name and days, and offers to prepare every day on this phone for offline use.
Your trips and saved hikes
Downloaded trips show whether they are ready offline on this phone, and which day is next.
Find a trail or plan a route
Guides with day plans and nights, or your own route in the Planner.
Going offline for more than a day
- Add TrailSplits to your home screen first (below). On an iPhone, then download inside the Home Screen app: Safari and the app keep separate storage, and Safari may clear a website's data after a while without use. On Android the browser and the app share their downloads.
- With signal, open the trip and tap Download whole tour (or Prepare all days in the app).
- Wait for "All days are ready offline on this phone". That is a check on this phone, not a guess: if something is missing it says so and offers a repair.
Works with no signal
The trip's map along the route, the route and each day's GPX, navigation with GPS, the trip page with its nights and the notices saved with it.
Needs a connection
Search, planning new routes, weather and new notices. Photos you take wait on the phone and upload when you next open Record with signal, signed in.
