One seventy-five
thirty days.
Lock in.
Pick one habit. Log it once a day. Watch the streak compound. A single-focus challenge with photo timelapses, a clean stats dashboard, and a Be Honest recovery flow when life gets in the way.
No checklists. No programs.
Just one thing, every day, for thirty.
75 Hard asks you to do five things at once. The Streaks app gives you fifty things to do at once. LockIn30 asks for one — chosen by you, locked for thirty days, with the room to recover when you stumble.
Built for finishing, not just starting.
How it works
Pick it. Log it. Lock it in.
Three steps to start, then nothing to learn. Choose a habit from the 36-task library — or write your own — and tap once a day for thirty days.
Pick one habit.
Browse 12 categories, 36 templates, or roll your own. Six task types cover anything: checkbox, counter, duration, photo, text, or measurement.
Pick a length & mode.
30 days by default — supported anywhere from 7 to 365. Strict mode summons the Be Honest dialog when you miss. Forgiving lets you skip without breaking the run.
Tap. Once a day.
Log from the bottom sheet on the dashboard. Streak tracks itself. Photo habits stack into a 1080×1920 timelapse you can save and share.
On your phone
The dashboard is the discipline.

One challenge in focus. Always.
The dashboard surfaces a single challenge at a time — its day count, its day grid, its next-tap. When you run multiple, swipe between them with a chip selector. No bottom tab bar. No tabbed graphs. No noise.
A daily affirmation rides above the card. A reminder rides below. That's the whole screen.
Everything
in the box
Built for finishing, not just starting.
A short list, on purpose. Every feature exists to keep you on the streak — or get you back on it after a miss.
30 days, compressed into a 5-second timelapse.

The principles
Focused. Time-boxed. Visible.
Focus.
One habit per challenge. No 75 Hard checklists, no parallel tracks. The challenge is the habit — not a program built around one.
Time-boxed.
30 days by default, anywhere from 7 to 365 if you want. Long enough to feel real. Short enough to start today.
Visible.
The day grid fills in. The streak counts. The timelapse renders. Progress you can see, share, and prove to yourself.
Screens
Every screen, one job.





Thirty days.
One habit.
Starting when you say.
