Free. Ad-Free. Built for physique athletes
Your key.
Your data.
Your gains.
APE started as a tool one physique athlete built for himself — and grew into something the community kept shaping. Track macros, log workouts, and get AI coaching — using whichever AI provider you already have. No subscription. No lock-in. No middleman.
Everything lives in your browser's local storage or your own Google Drive. APE has no backend servers. NARBE LLC never touches your data.
APE is the only fitness app that lets you supply your own AI API key. Use Claude, GPT-4o, Gemini, or any OpenRouter model — auto-detected from the key prefix.
No freemium gates. No ad network. No upsell paywalls. APE is and always will be free. If it earns a tip, great. If not, it's still yours.
What's inside
Everything a serious
athlete needs
Built feature-by-feature for physique athletes — not casual step counters. Every tool is designed around the way bodybuilders actually train and eat.
Log food with USDA FoodData Central search, Open Food Facts fallback, barcode scanning, AI food photo recognition, voice entry, and a full recipe builder.
Built-in program library, fully custom program creator, auto-progression tracking, rest timers, and complete workout history.
Point your camera at any meal and get instant macro estimates. Powered by your own API key — no subscription required.
Weekly training and nutrition suggestions generated from your actual logged data. Real context, not generic advice.
Share your data with a real coach via Google Drive. Coaches can push macro targets and training programs directly into your app.
Body measurements, progress photos with pose tagging, time-lapse comparisons, and trend charts across every metric that matters.
All your data syncs to your personal Google Drive. Switch devices seamlessly. NARBE LLC never touches it.
APE is a PWA — install it from your browser on any phone, tablet, or desktop. No app store. Works fully offline.
Built honestly
Not a startup.
Just a tool.
APE isn't trying to compete with Cronometer, MyFitnessPal, or any mainstream fitness tracker. It's an experimental app the APE community founder built because he wanted it for himself — and kept building because the community kept asking for more. Features get added based on what members actually request. Development moves fast because we use AI to write the code. There's no roadmap committee, no investors to answer to. Just one builder, a Discord full of athletes, and a shared goal of making something genuinely useful.
Bring your own AI
The only fitness app
that puts your AI
in your hands
Paste any API key from a supported provider. APE auto-detects who it's from — no dropdown, no config. Your key is stored only on your device and never included in sync data. AI calls go directly from your browser to the provider. We never see them.
