Four weeks. One tap a day.

No tour, no tutorial. See your end date, pick your track, start. Here is every step.

The four onboarding screens

Before you log anything, you see the promise. No signup wall, no tour.

First screen: "Day 1 of 28 begins when you start." Your end date is visible before any account is created. No friction, no tour.

Strength, cardio or mobility. One tap. No "surprise me." A real choice commits you to a real plan. Continue lights up after selection.

Today or tomorrow. The app immediately computes and shows your fixed finish date. That date does not move. Ever.

Five to eight people who started within 48 hours of you. Anonymous roster. Daily check-in ticks only. No messages, no leaderboard.

Under 30 seconds from open to done. That's the design.

Home screen. Day X of 28. Your current streak. Your fixed finish date. Nothing else fighting for attention.

One card. 140 characters or less. Clear, physical, doable today. No choice, no library, no decision fatigue.

One button. No form, no camera, no notes. The tick lands in your squad's roster. Logged in under 30 seconds. Back to your day.

Your streak breaks. The end date stays the same. Miss two in a row and you'll get a quiet nudge, not a shame message. Start again tomorrow.

The final challenge is named "Finish Week 4." Tap Done. Full screen. Your real numbers: days logged, streak, squad check-ins. That's the finish.

Pick a start date and the calculator shows your fixed day 28. That date is the one that matters.

Every paid fitness app gives you more. We give you less, on purpose.

Hundreds of workouts give you choice. Choice creates paralysis. One challenge removes it. You come back because it's simple, not because it's big.

Scheduled sessions work for people who already have a routine. We're for people who quit before week four. Asynchronous is essential.

Competition drives the already motivated. We're for the person who dropped out. A small squad that notices absence is enough. No rankings needed.

Start today and see your finish date before you create an account.
