iPhone
Trailmark Journal quietly remembers where your days take you.
It records your movement automatically in the background — no buttons to press, no check-ins. Whenever you're curious, open the app and replay any past day as an animated trail on the map, at your own pace.
WHAT YOU CAN DO
• Replay any day — watch your route draw itself across the map; scrub the timeline and change speed.
• Heatmap — see everywhere you've ever been, layered into the paths you travel most.
• Stay points — spots where you lingered 10+ minutes are marked automatically; save the good ones to Places.
• Places — keep your favorite spots, search for new ones, and see how far they are from where you are now.
• Daily dashboard — distance, time, and how you moved (on foot, bike, car, train), plus steps and active calories from Health.
• On this day — revisit what you were doing on this date in past years.
PRIVATE BY DESIGN
Everything stays on your device. Your location, steps, and history are never sent to any server, and there is no account to create. Your past is yours alone.
FREE & PREMIUM
Recording is always on, free forever. The free version lets you look back over the last 7 days. Unlock your entire history with a monthly or yearly plan, or a one-time Lifetime purchase — same full access either way.
Trailmark Journal isn't about sharing where you are. It's a quiet place to look back on where you've been.
