About this app

The ultimate home workout challenge. No gym. No equipment. Push-ups, sit-ups, squats and cardio — tracked, ranked, and gamified into a hero progression system.

OPM Challenge is a home workout tracker built around a daily fitness protocol that scales from beginner to elite. Complete the challenge. Rank up. Miss a day — and watch your streak die.

─────────────────────────────────
💪 HOME WORKOUT. ZERO EQUIPMENT.
─────────────────────────────────
No gym membership. No weights. Just your body and a phone.

The daily protocol scales with your hero level:
▸ Push-Ups — auto-counted by proximity sensor
▸ Sit-Ups — tracked by your phone
▸ Squats — rep counter built in
▸ Cardio — run, cycle, swim, skip, stairs, or burpees

Not a 30-day challenge with an expiry date. A daily workout habit for life.

🏆 HERO RANK SYSTEM

Every completed workout advances you along the Hero Odyssey — 100+ mission nodes, boss battles, and instant rank-ups.

N-Class ➜ C-Class ➜ B-Class ➜ A-Class ➜ S-Class

Your rank is earned. Never given.

📡 AUTOMATIC REP COUNTER
─────────────────────────────────
Your phone's proximity sensor counts reps passively — no tapping mid-set. Place the phone on the floor for push-ups. It counts as you move. No smartwatch. No Bluetooth. No extra hardware needed.

Ratings and reviews

Good app. I really would like to see some type of suggested progression. I had to come back to the app store to see the that you suggest at least three days before leveling up. Once there is some suggested progression it should be easily referenced in the app itself. Are you storing the data of users? If so you could data mine the most successful progression routes. Imagine a machine learning model that uses wieght, sex, time to complete X kms, etc to suggest when to level up.

It's awesome. Only thing I hope they can add is a custom setting to add either a pull up or a row as an additional exercise into it. Not the OPM routine, but adding a back pulling movement would be useful. If you don't want it you leave the setting off. If you do you just turn it on in settings.

Looks awesome, but installed and just keeps crashing... Help? Update 1: Upgraded one star because developer reached out to try to help and said they'd keep me posted. Either way, did 100 pushups, situps and squats today with a 10k run :D. Update 2: developer walked me through some troubleshooting steps, I had an incomplete account because I backed out of the sign up to figure out my weight in kg, but once I deleted and reinstalled the app knowing my kg weight instead of pounds it set up nice.

What’s new

• Push-ups, Sit-ups, Squats, and Running now display correctly for all users.
• OPM checks for updates on launch and prompts a restart when one's ready.
• Rate OPM inside the app after a 3- or 7-day streak.
• Workout summary now shows the exercise name on every set card.
• Streak count was stuck at 0 after completing workouts.
• Stopping a run from the notification no longer wipes distance and time.
• Sit-ups and Squats now beep each rep and whistle at each set end.
