Try the brand new viral body scan feature! Bert will draw you as a stick figure, give you a rating (if you want), and show what your transformation could look like!
You could download another fitness app. One with fancy graphs and motivational quotes and a voice that says "great job!" when you do a single squat.
But you didn't. You found Bigbert.
Bert is a stick figure. (Berta too, if that's more your vibe.) They live in your phone. When you work out, they get bigger, stronger, and evolve into something beautiful. When you skip a day? They shrink. They lose XP. They look at you with their little circle head and you just know they're disappointed.
That's it. That's the app.
HOW IT WORKS:
- Tell Bert (or Berta) about yourself — experience, goals, equipment, injuries. They actually listen.
- Send Bert a photo of yourself. He'll turn you into a stick figure. It's brutally honest.
- Their AI builds you a real workout plan in seconds. Not cookie-cutter nonsense. YOUR plan.
- Do the workout. They walk you through every exercise with animated demos, rest timers, and guided warmups.
- Earn XP. Watch them evolve from a sad little doodle into an absolute unit.
- Skip a day. Watch them shrink. Feel things.
BODY SCAN:
Upload a mirror selfie. Bert's AI turns you into a stick figure version of yourself — same pose, same outfit, same vibe. Then he shows you a transformation of what your stick figure could become. It's weird. It's fun. You'll send it to everyone you know.
12 LEVELS OF EVOLUTION:
Your stick figure starts pathetic and ends legendary. Every workout pushes them forward. Every skipped day drags them back. 12 stages of evolution, from barely-a-doodle to full gym bro (or gym sis). You'll care more about this little drawing than you expected. That's by design.

- Bertify body scan that turns your photo into a stick figure
- Before/after transformation preview — see your stick figure's potential
- AI-powered workout plans tailored to your body, goals, and equipment

- A stick figure whose emotional wellbeing depends entirely on you
Don't let them down. They're already warming up.
