It's not motivation. It's the gym — the mirrors, the locker room, the wondering if your form is wrong. Take all of that out and what's left is the part that actually works: 20 minutes, your body, a room you already feel at home in.
Same workout. Different room. No spectators.
The form companion
We'll count.
We'll watch quietly.
You won't notice.
Lean your phone on a backpack. Pose detection runs entirely on your phone — no video, no cloud, no upload. Ever.
Rolling out in v1.5
Phone at hip height
Lean it on a chair or backpack. No tripod required.
100% on-device
No video uploaded. Not to us, not to anyone.
Full body in frame
Toes to head, side angle. The app tells you when you're set.
Inside the app, this is one button. Outside the workout, it isn't on at all.

Programs, not prescriptions
Pick a path.
Or build your own.
Curated 4-week paths for Beginner, Intermediate, and Advanced. Each is bodyweight-first; add dumbbells if you've got them, a band if you don't. Switch programs without losing your streak — the app remembers where you were.
Beginner
4-Week Foundation
16 sessions · bodyweight only
Intermediate
Push Pull Legs
4 weeks · dumbbells optional
Advanced
Starting Strength
5×5 progression · barbell-friendly
Past programs stay in your history with their actual ending — including the day you switched to Beginner. We don't pretend.
The kindest difficulty knob
How was that?
Hard. Just right. Easy.
After every workout, three buttons. That's the whole feedback loop. The next workout adjusts itself — no Garmin watch, no 1-rep-max protocol, no asterisks.
Goldilocks, applied to push-ups.
Streaks that forgive you
Miss a day?
The streak waits.
Rest days auto-freeze your streak — Sunday, sick week, vacation. You can't break it by living your life. The flame just pauses.
"Recovery day. We auto-froze your streak. Rest is how you get stronger."
Inspired by James Clear's "never miss twice." Built so you can miss thrice and still come back.
60+ moves, no mystery
Every move, demoed cleanly.
Push, pull, legs, core — sorted by what you're working, not by what's trendy. Tap any exercise to see the figure in motion. No 12-minute YouTube intro.
Don't see what you need? Suggest it. We read every one.
Why it stays out of your way
Built like a tool,
not a coach.
Bodyweight by default
Start with what you have. Most programs run 4 weeks without a single dumbbell.
On-device pose detect
Form watching runs entirely on your phone. No video uploaded. Ever. (v1.5)
20 minutes, every time
Calibrated to fit between meetings, before kids wake up, after dinner.
No shame, ever
Skip days. Switch programs. Start over. The app never punishes you for being human.
FAQ
Honest answers.
- Do I need a gym or any equipment?
- No, by design. The default is bodyweight. Programs that use dumbbells, bands, or a bench show that up front so you can pick what fits your living room.
- I'm starting from zero — is this for me?
- Literally yes. "I'm starting from zero" is one of the goal options on Day 1, and the Beginner path is built around it. No assumed knowledge, no implied gear, no shame.
- What is the AI Form Companion and is it watching me?
- It's a feature that counts your reps and quietly flags obvious form issues using pose-detection running entirely on your phone. No video leaves your device. Ever. You can also leave it off — workouts run fine without it. The companion ships in v1.5; the bodyweight programs and library are live from day one.
- What if I have an injury?
- Day-1 onboarding asks about knees, lower back, shoulders, neck, and pregnancy. Programs adapt automatically. If you're between flare-ups, you can switch to a gentler path anytime without losing your streak.
- Does it work offline?
- Yes. Workouts, the exercise library, and the form companion all run offline. Streak sync needs a connection once a day; it'll catch up when you're back.
- What if I miss a week?
- Your streak auto-freezes on rest days. You also have 2 freezes per month for any day. If you miss more than that, we'll quietly offer a 50% restart — no shame, no penalty.
- Who builds Simple Gym?
- Simple Gym is built and maintained by SimpleApps — the same one-person team behind Simple Reminder and Simple Photographer 101. Indie, no investors, no dark patterns. simpleapps.ai.
