Why Mark is different
📵
No Account
Start tracking immediately. No signup, no password, no email required.
☁️
No Cloud
Your data lives on your phone. Not our servers. Not anyone's servers.
🚫
No Ads
We don't sell your attention. We sell a product. That's the whole business model.
📱
Yours Forever
Everything stays on your phone. No subscription required to access your own habits.
Built different
01
Streak Engine
One tap check-off. Auto-break if you miss a day. Best streak tracked per habit. That's the whole mechanic. Nothing else competes for your attention.
02
Streak Note
Optional 280-char note on every check-off. Not a journal — just a trace. A lightweight record of why you showed up today.
03
Tally Mark View
Your streak visualized as actual tally marks — the oldest counting system humans have ever used. You can see the shape of your consistency.
04
Smart Notifications
Custom reminder per streak. Timezone auto-detected from your device. Morning summary. Streak-at-risk alert. All local. No server.
05
4 Screens. One Mechanic. Nothing Extra.
Home — Add Streak — Streak Detail — Settings. That's the whole app. We deliberately chose to build less so every part of what exists is excellent. Simplicity is the feature.
