Beta 4 is open
Every hike you have done, in one place you actually keep.
Trailmark logs the walk, draws the climb, files your photos and hands you a trail card at the end. No subscription during the beta, no leaderboard, no strangers rating your Sunday.
Free for testers, no card needed. iOS 16 and up, Android 12 and up.

It works the way a hike actually goes.
- 1
Tap start at the trailhead
One tap and the phone goes back in your pocket. Trailmark keeps recording with the screen off, in airplane mode, in the rain.
- 2
Take photos like you already do
Shoot with your normal camera. When you finish, Trailmark pulls the hike photos in and pins each one to the mile where you took it.
- 3
Get your trail card
Stop the log and the hike is written up for you: route, climb profile, moving time and your best photo on one card worth keeping.
What is in the app
Six things it does well, instead of forty it does badly.
One-tap hike log
Start the log at the trailhead and put your phone away. Distance, pace and moving time record themselves.
How it worksElevation you can read
A clean climb profile instead of a wall of numbers. See where the grade bit and where you cruised.
How it worksPhoto journal
Photos land on the map where you took them, next to a note you can write in ten seconds.
How it worksShareable trail card
One tidy card with the route, the climb and your best photo. Send it to a friend or keep it private.
How it worksOffline maps
Download the map before you lose signal. The log keeps running whether or not you have bars.
How it worksSeasons and streaks
Your year on the trail in one view. Gentle goals, no leaderboards, no strangers ranking your hikes.
How it worksA look inside
Four screens you will live in.

Pinned to the mile
“We built the offline engine first, because that is the part every other app gets wrong at mile six.”

What testers keep telling us.
These are placeholders. Replace them with real reviews from your own testers or your Google listing.
“I hiked the same loop in June and again in September and the app put the two climb profiles side by side. Never had a reason to look at my old hikes before.”
“Lost signal an hour in and it kept recording the whole way. The map was already downloaded, so I never had that moment of staring at a gray screen.”
“The photo journal is the part I actually use. My notes from a windy day in April are still there with the picture, right at the mile they happened.”
Come test it on your next hike.
