No content library
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.
Four weeks. One tap a day.
How FitSphere works.
No tour, no tutorial. See your end date, pick your track, start. Here is every step.
The four onboarding screens
Before you log anything, see the promise.
- 01
See the promise
First screen: “Day 1 of 28 begins when you start.” Your end date is visible before any account is created. No friction, no tour.
- 02
Pick your track
Strength, cardio or mobility. One tap. No “surprise me.” A real choice commits you to a real plan.
- 03
Choose your start date
Today or tomorrow. The app immediately computes and shows your fixed finish date. That date does not move. Ever.
- 04
Land in a squad
Five to eight people who started within 48 hours of you. Anonymous roster. Daily check-in ticks only. No messages, no leaderboard.
The daily loop
Under 30 seconds, open to done.
Open the app
Home screen. Day X of 28. Your current streak. Your fixed finish date. Nothing else fighting for attention.
See one challenge
One card. 140 characters or less. Clear, physical, doable today. No choice, no library, no decision fatigue.
Tap Done
One button. No form, no camera, no notes. The tick lands in your squad's roster. Logged in under 30 seconds.
Miss a 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.
Day 28: Finish Week 4
The final challenge is named “Finish Week 4.” Tap Done. Full screen. Your real numbers: days logged, streak, squad check-ins.
Your finish date
See your finish date right now.
Pick a start date and the calculator shows your fixed day 28. That date is the one that matters.
The trade-off we made deliberately
We give you less, on purpose.
No live classes
Scheduled sessions work for people who already have a routine. We're for people who quit before week four. Asynchronous is essential.
No leaderboard
Competition drives the already motivated. A small squad that notices absence is enough. No rankings needed.
You've quit before. This one has an end.
Start today and see your finish date before you create an account.
