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. FEATURES: - 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 - Guided workout mode with exercise animations, rest timers, and full warmup/cooldown phases - XP system that rewards consistency and punishes excuses - Sarcastic encouragement that somehow works ("bert sees you. bert is impressed. mildly.") - Hand-drawn notebook aesthetic that looks like nothing else on the App Store - A stick figure whose emotional wellbeing depends entirely on you Don't let them down. They're already warming up. Free to download. Full access requires a subscription or lifetime purchase. Weekly, monthly & yearly subscriptions are available. Subscription unlocks full AI workout plans and all 12 levels. Payment will be charged to your Apple ID account at confirmation of purchase. Subscriptions automatically renew unless canceled at least 24 hours before the end of the current period. Manage subscriptions in your Account Settings.
