Features
Six things it does well, and a short list of things it will never do.
Trailmark is a log book, not a social network. Every screen below is in the current beta build, on both phones, with nothing locked behind a plan.
One-tap hike log
Start the log at the trailhead and put your phone away. Distance, pace and moving time record themselves.
- Starts recording from the lock screen
- Auto pause when you stop for a snack
- Works with the screen off and the phone in a pocket
- Edit the start and end points afterward
Elevation you can read
A clean climb profile instead of a wall of numbers. See where the grade bit and where you cruised.
- Barometer and GPS blended for a steady reading
- Total gain, biggest sustained climb, high point
- Grade shading so steep sections stand out
- Compare today against the last time you hiked it

Photo journal
Photos land on the map where you took them, next to a note you can write in ten seconds.
- Pulls the hike photos out of your camera roll
- Pin a photo to the exact mile marker
- Short notes, weather and trail conditions
- Nothing leaves your phone until you say so
Shareable trail card
One tidy card with the route, the climb and your best photo. Send it to a friend or keep it private.
- Route, distance, gain and time on one card
- Pick the photo and the color theme
- Share as an image or a private link
- Location can be blurred for sensitive spots

Offline maps
Download the map before you lose signal. The log keeps running whether or not you have bars.
- Download a region in about a minute
- Topo lines, water sources and junctions
- Battery saver mode for long days
- Everything syncs when you get service back
Seasons and streaks
Your year on the trail in one view. Gentle goals, no leaderboards, no strangers ranking your hikes.
- Monthly mileage and elevation totals
- Peak lists you can build yourself
- Set a season goal and track it quietly
- Export a year summary any time

Just as important
What Trailmark will not do.
Written down here so you can hold us to it, and so you know what you are signing up for.
- No ads, ever, in any build
- No follower counts and no public feed
- No selling your location history to anyone
- No holding your hikes hostage: GPX export is always free
