Trail Tracker

Trail Tracker is the race-day companion built for ultra runners.

Plan your entire race schedule before the start gun fires, then track your progress checkpoint by checkpoint on race day — all without needing an account or an internet connection.

── PLAN YOUR RACE ──
Add as many races as you like. Give each race a name and start date, then build out your checkpoint list from start to finish. For every checkpoint you can record:

• Total distance to that point
• Elevation gain from the previous checkpoint
• Expected arrival time and cut-off time
• Available facilities: water, food & drinks, warm meal, dropbag, sleeping spots, and crew access

── RACE DAY TRACKING ──
Open your race on the day and check off checkpoints as you pass them. Trail Tracker records the exact time you hit each checkpoint and instantly shows you whether you are ahead of or behind your expected pace — in green when you're ahead, red when you're behind.

── FULLY OFFLINE & PRIVATE ──
Trail Tracker stores everything locally on your device. No account, no sign-up, no cloud sync, no internet connection required — ever. Your race data never leaves your phone.

── CLEAN & FOCUSED ──
Built with Jetpack Compose, Trail Tracker has a clean Material 3 interface with full dark mode support. No ads, no trackers, no distractions — just you and your race.

Perfect for ultramarathons, trail races, mountain races, and any multi-checkpoint endurance event.
