Enter a goal and AI turns it into a mountain you can climb. Today's step takes 15 minutes, and you tick off each task as you go. No streaks, no nagging. 7 free days.
TRAIL turns your biggest goals into mountains you can actually climb.
"Pass the AWS exam." "Write a novel." "Run a 5K." —
You know what you want, but it feels too big to start.
TRAIL uses AI to break your goal into a single climbing route made of chapters and missions.
Each mission takes as little as 15 minutes. Climb today's step, and the summit gets closer.
■ Your goal becomes your own mountain
- Enter a goal and AI generates a roadmap of chapters and missions
- Every mission states exactly what "done" means, so you never wonder what to do
- The route adapts to your deadline, experience, and pace
■ The scenery changes as you climb
- Clear a mission and the trail extends, the fog lifts, your elevation rises
- From the forest at the foot, past the treeline, up the ridge, to the summit
- Every clear ends with a quiet celebration
■ Bad days are part of the climb
- A mission too big? Split it and redraw the route
- Busy today? Leave a footprint with "enough for today"
- Away for a while? You'll be welcomed back — never scolded
- No streaks. Missing a day never erases your trail
■ Your record becomes an asset
- A climbing calendar, total elevation, and comparisons with real famous peaks
- Weekly review cards and shareable summit certificates
- All records and notes stay on your device
Stack one 15-minute step a day.
One day you'll look up and realize you're standing on the summit.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
■ A guided first climb
The first few minutes now walk you up three real steps, including how to split a step that feels too big.
■ Tick off each task
You can now check off a mission's "done when" items one by one. Checks are saved, so closing the app mid-work is safe. You can also track the time you spend.
■ Photos, straight from the slot
Camera and library now sit side by side from the start.
■ Easier records and notes
Records are grouped by day, and notes now lead with what you wrote. Settings has been tidied up too.
■ Fixes
The progress bar could fail to draw, and larger text sizes could overflow the tab bar.
