HOW IT WORKS
THE WORKOUT ENGINE
This is the core loop. Everything else supports it.
One tap. FORGE picks muscles, session length, and builds your workout. Zero thinking.
Your last 4 sessions + recovery → AI returns exercises, weights, reps, and cues.
Hit top of rep range → add weight. FORGE tells you when to progress.
Per-muscle freshness. Only recommends what your body is ready for.
Volume PRs auto-detected. Trophy banners. Streak messages.
Auto-starts per exercise type. 3/2/1.5 min by compound/accessory/isolation.
Rate Easy/Med/Hard per set. FORGE auto-adjusts next workout.
Replace, reorder, or remove exercises mid-workout. Your rules.
THE ECOSYSTEM
Meals, supplements, cardio, weight, and more — all feeding into one system.
Photo or label → exact macros. One-tap re-log saved meals.
Calorie ring. Macro bars. Quick log. AI macro goals by body type.
Build your stack. One-tap TAKE ALL. Daily compliance.
Ask anything. One AI brain sees workouts, meals, supps, weight.
Tap ? for AI form cues, target muscles, common mistakes.
One number (0–100) across training, nutrition, recovery, and more.
Stairmaster HIIT, intervals, incline walks, Zone 2. Structured sessions.
Daily tracking. Trends. Feeds into AI context and FORGE Score.
YOUR AI, YOUR RULES
FORGE doesn't lock you into one provider. Pick Claude, ChatGPT, or Gemini. You bring the key, pay the provider directly, and FORGE never sees your billing. Your key stays AES-256 encrypted on your device.
$5 loaded lasts weeks. Most people barely notice the cost. FORGE encrypts your key locally — we never see it.
SEE IT IN ACTION
Every screen designed for dark gyms, one-hand use, and zero wasted taps.

TESTFLIGHT BETA
Welcome to the FORGE beta. Here's everything you need to get set up and start training.
You'll receive an email invite from Apple TestFlight. Open it on your iPhone → tap "View in TestFlight" → install the TestFlight app if you don't have it → then install FORGE. That's it — the app icon appears on your home screen.
First launch walks you through: name, gender, body weight, goal (build muscle, lose fat, physique, etc.), training experience, equipment access, schedule, meal philosophy, and macro goal. This shapes everything — workout bias, exercise selection, calorie targets, and AI recommendations. Takes 2 minutes.
FORGE needs an AI API key to power smart features. You bring your own — pick one provider, sign up (free), create a key, and paste it in Settings. Load $5 of credit and it'll last weeks. FORGE encrypts your key on-device and never sees your billing.
Here's everything in the beta. Try them all and tell us what works and what doesn't.
We're looking for real-use feedback from actual training sessions. Here's what helps most:

YOUR DATA. YOUR DEVICE.
FORGE is built on a simple principle: your fitness data belongs to you. It stays on your device. We don't collect it, store it, or sell it.
All workout history, meal logs, body weight, supplements, cardio sessions, step counts, profile data, FORGE Score, and coach chat history are stored locally on your device. FORGE does not transmit this data to any server we operate.
FORGE allows you to connect your own AI provider (OpenAI, Anthropic, or Google) using an API key you provide. Your key is stored locally on your device only, never sent to FORGE servers, and used exclusively for direct communication between your device and your chosen provider.
DISCLAIMER: Ledesma Enterprises LLC and FORGE Workout OS are not responsible for any charges, costs, overages, or fees incurred through your AI provider account. You are solely responsible for managing your API key, usage limits, billing alerts, and spending caps. If your key is compromised, leaked, or misused for any reason — including device theft, shared access, or third-party exploitation — FORGE bears no liability for resulting charges or damages. Set spending limits directly with your AI provider.
FORGE requests camera access solely for meal scanning and barcode scanning. Camera data is processed locally or sent directly to your AI provider. FORGE does not store, transmit, or retain camera images on any server.
We collect minimal data only when you voluntarily submit it: beta application forms and waitlist signups (name, email, training info). Processed via Formspree. Used solely to communicate with you about FORGE. We do not sell, rent, or share this data with third parties.
FORGE does not use cookies for tracking, analytics services, advertising SDKs, tracking pixels, fingerprinting, or device identification of any kind.
Formspree (form submissions), Open Food Facts (barcode lookup — only barcode numbers sent), AI providers (OpenAI, Anthropic, Google — direct device-to-provider when you provide a key), and Google Fonts. Each has its own privacy policy.
Your data is yours. Export via Settings, or delete everything through Settings → Clear All Data. Deleting the app removes all FORGE data permanently.
FORGE is not intended for individuals under 13. We do not knowingly collect personal information from children under 13.
