Trailhead
Workout-programme tracker for Android — the companion to Cairn

Pick a programme. Keep showing up.

Trailhead lines up your next session, reminds you on your training days, and counts progress in sessions, not dates — so a missed day loses nothing. No account, no analytics, no adverts — your progress and measurements never leave your phone.

What it does

A real programme library

Abs, Arms, Legs, military conditioning and more, in Easy/Tough/Extreme and 4- or 8-week lengths. A few ship in the app; the rest are an opt-in download.

A Today card that remembers your place

Next session, its steps and form cues, Done or Not today. Undo is exact, and you choose whether to move on or repeat a week at the end of each phase.

Guided workouts

A timer for each exercise, a rest countdown with beeps, pause or end any time. Optionally saves the finished workout to Health Connect — off by default.

Reminders that stay quiet when earned

A daily notification on your training days, silent if you've already trained. Mark a session done straight from the notification.

Progress without guilt

Weekly consistency and streaks — a week still in progress never breaks one — plus weight, body fat and height trends read from Health Connect.

Your own backup

Save progress to a file you choose and restore it after reinstalling or switching phones. There is deliberately no cloud backup.

Private by design

Trailhead has no account, no adverts and no analytics. Your progress and measurements stay on your phone. The only thing it uses the internet for is an optional, off-by-default check for new programmes, which sends nothing about you.
