MTB, hike, run & gym.
Your private personal trainer.
The private GPS tracker with a coach built in: week-by-week training plans, a strength trainer that talks you through every session, and every stat, kept on your phone and never uploaded. Free from subscriptions, ads and tracking.
Real screens from the TrailFree app. Pick a tab, and try light or dark.

Free from the things that get in the way.
Free from subscriptions
The whole tracker is free. Pro is a single one-time purchase for the depth, with no monthly bill to keep it working.
Free from ads
No banners, no promos, no interruptions. Just you, your outing, and the map in front of you.
Free from tracking
No account, no analytics, no trackers. Your outings, routes and records stay on your phone, and yours to export.
Satellite, with the trails drawn on top.
Aerial imagery shows the ground as it actually is: the firebreak, the treeline, the bend in the river. Over it sits the trail network, so a path that disappears under canopy is still a path you can follow. Shaded relief underneath tells you which way the hill goes before you are standing on it.
- Satellite with trails, plain satellite, or topographic
- Shaded relief, so the terrain reads at a glance
- Download an area and leave the signal behind
- Your route drawn as you go, and kept when you are done
Map styles and fonts from OpenFreeMap, built on data by OpenStreetMap contributors. Satellite imagery by Esri, Maxar, Earthstar Geographics, and the GIS User Community. Terrain tiles by Mapzen, hosted on AWS Open Data. Rendered with MapLibre. All of it is keyless, so none of these sources is ever told who is asking.
Train for something. It plans the way there.
Name a goal, like a 100 km ride or a first 20 km walk, and get a week-by-week plan built on the same principles good coaches use. It watches the outings you record and adapts. All on your phone, no monthly subscription.
Built the way coaches build
Base, Build, Peak and Taper, with the load capped at a safe +10% a week and a recovery week every fourth.
It reads your log
Recorded outings tick off your sessions automatically. Miss a week and it rebuilds the rest from what you did.
Optional heart rate monitoring
Pair a Bluetooth strap and sessions gain heart-rate zone briefings, so you can see which efforts are easy and which are hard.
See exactly how the trainer works, every rule and formula
Free tools and guides: calculators, plans and training know-how
A gym log that trains you back.
First it asks what you're training for, and what you've got to train with. Then it hands you the routines to match: 12 routines and 43 exercises, from bodyweight to a barbell, with form cues, a rest timer, quiet records, and weights in kilograms or pounds.
Built around your kit
Set a focus and your equipment, from bodyweight and bands to dumbbells, a bench and a barbell, and every routine resolves to the best lift you can do with what you have.
Adaptive prescriptions
Hit every rep and it moves you on: “last time 3×8 at 40 kg, today try 42.5.” Fell short? It holds where you are.
Counts toward the plan
Log a strength session and your training plan's strength day ticks itself off. Your best lifts are recorded without any fanfare.
A trainer that talks you through every set.
Pick a routine and how long you've got, 30, 45 or 60 minutes, and TrailFree runs the session out loud. Get ready. The lift, and the weight to load. Do the set. Rest. Next. Hands-free, screen off, like a coach standing next to you.
- Fits the routine to your time and the kit you own
- Calls each lift, weight and rest, with on-device speech
- Nudges the weight next time, read from what you logged
- Writes the session up when you're done
Set your own mark.
Private challenges, measured only against yourself. Take one on, or build your own from any metric, target and window.
Everesting, gently
Climb 8,848 m, the height of Everest, inside a month.
Century month
Cover 100 km inside a month, any way you like.
Seven days outside
An outing every single day for a week.
The depth of a paid app. None of the spying.
Splits, gradient, climbs, terrain, personal records, trends over weeks and years, and a private heat map of everywhere you've been. All computed on your phone, and all yours to keep.
Most fitness apps
- Your deepest stats sit behind a monthly subscription
- An account and the cloud, whether you want them or not
- Your routes and habits become someone else's data
- One look, take it or leave it

- No account needed, no trackers, no ads
- Your data stays with you, export anytime as GPX
- 16 themes, a studio, and boldness, to make it yours
One app. Sixteen ways to look at it.
The same screen, four of the sixteen packs. Each one carries its own colours through your route, your charts and every corner of the app. Pick a photo backdrop, set how loudly it renders, and pair a theme for daylight with one for the dark.
Choose your coach's personality.
Set a weekly goal: distance, outings, time, climbing, steps or days out. Then choose a voice, or silence. On-device speech, off by default.
Enjoy. The trail is all yours.
Off we go. Settle into your rhythm early.
Adventure time. Let's go.
Quit negotiating. Shoes. Outside.
Real silence, just you and the trail.
