You start every 30-day challenge fired up on day one and quietly ghost it by day nine. The app pinging you to "log your workout" is easy to ignore, because nothing happens when you don't. And group challenges somehow always come down to that one person swearing they did their pushups off-camera while everyone else did the work — so nobody trusts the leaderboard, and the whole thing fizzles.
- Motivation evaporates around day four, and there's zero real consequence for skipping — so you skip.
- Streak apps and habit trackers run on the honor system; a tap says you 'did it' whether you moved or not.
- Group challenges collapse the moment someone claims reps nobody saw, and the leaderboard becomes a lie.
- You've spent 30 days getting nowhere before, and you're not sure this attempt ends any differently.
How Cadoo solves it
Real money keeps you honest all 30 days
Bet your own cash with friends on finishing the challenge. When quitting means losing money — and sticking with it means taking home everyone else's stake — day 18 suddenly feels as urgent as day one. It's the accountability a reminder notification will never give you.
Every rep is verified, so a win is a real win
Cadoo counts and form-scores your pushups, squats, situps, pullups, dips, and plank holds straight from your phone camera, and reads your daily steps from Apple Health or Google Health Connect. Half-reps and phantom workouts don't count — which means nobody can cheat their way to your money, and your win is genuinely earned.
A challenge with friends that actually stays fun
Compete on live leaderboards, climb the leagues, and turn your best sets into shareable, skinned highlight clips worth posting. The stakes make it serious; the social side and the trash talk make you want to open the app every single day.
Frequently asked questions
How does the money part of the challenge actually work?
You and your friends each put a stake in before the 30 days start. Everyone who completes their verified workouts through the challenge splits the pot — so the people who show up take home the money from the people who didn't.
How does Cadoo know I really did the workout?
For pushups, squats, situps, pullups, dips, and plank holds, Cadoo uses your phone camera to count reps and score your form with AI. Daily steps are read straight from Apple Health or Google Health Connect. The camera handles reps only — it never counts steps — so every result is verified, not self-reported.
What if I miss a day partway through the 30?
That's the whole point of the stakes — missing your workouts puts your money at risk. Knowing real cash is on the line is exactly what gets most people through the days they'd normally skip, all the way to day 30.
