You put in the work this week. Now you can see it. MammothFit weighs everything you lift and stacks it into a herd — a gorilla, a sumo, a mammoth. Every kilo counts: kettlebell swings, a heavy squat, ten seconds of front lever, the last kilometer. One glance tells you whether the week added up or slipped. No spreadsheet to decode. Just the herd you earned. YOUR HOME SCREEN IS THE TROPHY Every session adds animals to your home screen. The wall starts empty on Monday and fills with exactly what you earn — the silhouettes on it weigh what you lifted, to the kilo. Cross six tonnes in a week and a mammoth walks in. Open gallery mode, save the wall, and your week becomes your lock screen. That's the point of proof — you don't have to argue it. A big week is two mammoths. A lighter one is a gorilla: still real, still yours. The picture reads the same for everyone — women and men, first week or tenth year, beginner or beast. Earned pride, not a participation badge. And the flex finishes where the work does. The moment you log your last set, the trophy is already made — a clean black-and-gold card, good enough to send to the group chat without a caption. The memo and the flex are one act. THE HERD IS REAL WORK - Kettlebell complexes, done right. Build the complex, set work / rest / rounds — EMOM style if you want — and run a full-screen circuit timer with an arena buzzer that cuts through music and earphones. A live countdown stays on your lock screen. - Calisthenics holds that count. Front lever, planche, L-sit — timed to the second, with hold PRs to chase. - Bodyweight becomes real volume. Biomechanical factors convert pull-ups, dips and push-ups into honest kilos, so the herd is never a guess. The formulas are public. - Cardio in the same log. Pace and distance sit next to your lifts, not in another app. BUILT FOR HYBRID ATHLETES If you swing, hold, lift and run in the same week, half of that work usually goes unseen. MammothFit is built for all of it — one log, one herd. SEE THE PROGRESS UNDER THE PRIDE A dashboard per modality: estimated 1RM, kettlebell density, running pace, longest hold. PR milestones mark the moments the work moved. YOUR AI COACH, YOUR TERMS Export a clean prompt to the ChatGPT or Claude you already use, then paste the plan back as a checklist you can train from. No monthly AI fee. Your data never leaves the device. NO CATCH - No ads. No subscription. - One-time Pro unlocks unlimited AI imports, themes, and future animal packs. - Local-first and private. No account required. Log the work. Earn the herd. Show what a hard week looks like.
