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.

Obsessed

Obsessed is not a wellness app. It does not celebrate you for showing up. It takes the goal you claim, turns it into a standard, and checks every day whether your actions matched it. YOU BRING YOUR OWN TRAINING Type in the split you already run, import it from Strong, Hevy or FitNotes, paste a written program, or copy a friend's with an eight-character code. If you would rather we wrote one, we will. Either way it becomes the standard you are held to - and it learns: finish a session we never prescribed and that weekday becomes part of your week. PROGRESSIVE OVERLOAD, DECIDED BY THE WORK Top your rep range on every set and the weight goes up. Come up short and it holds. Leave early and it holds too - no easier target for doing less. Drop sets, back-offs, warm-ups and sets to failure are each judged on their own terms. FOOD, CHECKED AGAINST THE GOAL YOU CLAIMED Type what you ate in your own words, or enter the barcode and get the numbers off the box. We do not recommend a diet. We check whether what you logged aligns with the goal you set - calories and protein, two-sided and asymmetric, with the tolerance your goal actually implies. A GRADE EVERY DAY, AND A RECEIPT EVERY WEEK Training and nutrition fold into one letter, S to F. Monday morning brings a receipt: sessions trained, aligned days, what moved on the bar, what it cost you. CONSEQUENCES THAT MEAN SOMETHING Three bad days and you are on The Bench for seven - locked out, history kept. Injury, sickness and emergencies are answered honestly, and you get one waiver a month. Travel is declared in advance, not used as an excuse afterwards. Two clean weeks at an A clears a strike. THREE VOICES Locked In is direct. Obsessed is sharper. Possessed does not let anything go. The voice changes; the standard never does. Obsessed attacks the behaviour, never the person. Obsessed is $14.99/month or $89.99/year, starting with a 14-day free trial. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel any time in your App Store account settings.

Verdict
The clearest difference is in-app purchases: Obsessed at none against Bigbert's 6. Obsessed also leads on ads (none vs shown). On price, update cadence, device support and iOS requirement there is nothing between them.
