One tap
No blank page. No form to fill. You touch the pulse and it's already saved — before the feeling has a chance to pass.
Mark — by Elva Lab
Mark this moment.
A living pulse breathes on a black screen. Tap it, and this moment is yours — the exact time, the place, and whatever you want to say about it.
Free to start. No account, ever. Everything stays on your phone.
One idea, done well
The shortest distance between a moment and keeping it.
Time and place
Every mark remembers the exact minute and where you were standing. Later, that's often all it takes to bring the whole moment back.
Yours alone
No feeds. No streaks. No one watching. Your moments live on your phone and nowhere else — for you to find again, quietly.
The pulse
Tap the light.
At the center of Mark, a point of light breathes on pure black — slow and alive, like something with a heartbeat. Touch it once, and the moment is kept: the exact time and where you're standing, held in an instant. No sign-in, no setup, no thinking about it.
Marking a moment is always free.
Add as much or as little
Say more. Or say nothing.
A bare tap is already a whole moment. When you want to, add a line of text — a word, a sentence, a paragraph. Speak it aloud as a voice note, or take a photo right there in the light. Tag it — morning, evening, walk, idea, feeling, todo — or make tags of your own.
Voice notes, camera photos, and custom tags are Mark Plus. Photos are taken live in the moment — Mark never opens your library.
Look back
Some days deserve to be found again.
Your latest marks wait for you in a quiet stack on the Home screen. Below them, a calm History gathers your days, grouped one by one. Nothing to keep up with — just the moments, in the order you lived them.
Always free
Every place you've been
Your life, glowing on a map.
Open the map and see every moment you've ever marked, each one placed exactly where it happened. Points of light scattered across a dark canvas — a walk home, a trip, an ordinary Tuesday. Your own quiet constellation.
Mark Plus
Return to one
Step back inside a moment.
Open any mark and it comes back whole — the minute it happened, the spot on a small map, and whatever you added: your words, your voice, your photo. Small things you'd have lost, kept exactly as you left them.
The time, place, and text note are free. Voice and photos are Mark Plus.
Make it yours
Make it beat like you do.
Choose from four pulse styles — a lotus breath, a rippling wave, quiet rings, a slow spiral — and four accent colors in violet, gold, red, or blue. Your pulse and color follow you everywhere: the app, the app icon, the Home Screen widget, and the face of your Apple Watch.
Violet
Gold
Red
Blue
All styles & colors are Mark Plus
By design
Yours. Only yours.
Everything you mark is stored on your device and nowhere else. No account to make, no cloud, no tracking, no analytics. Your moments are never shared. And if you like, you can seal the whole app behind Face ID.
On-device storage is standard. Face ID lock is Mark Plus.
Mark Plus
Go a little deeper, when you want to.
Marking a moment is complete on its own. Mark Plus is for the days you want to hold more of it — a voice, a photo, a map of everywhere you've been, and a pulse made entirely yours. It only ever adds to the moment; it never locks the basics away.
