Spotter: AI Workout Companion

Spotter is the gym tracker built for lifters who care about the benefits of rest time between sets and workout progressive overload. Just a clean, focused tool that lives offline, logs your sets accurately, and turns your training history into useful information.

WHAT'S IN THE APP
• AI workout plans and sessions generator
• 873-exercise catalog covering every major movement
• Warmup and working sets tracked separately — PRs only count from working sets
• Real PR charts: tap any exercise from history to see your top set per session
• Rest timer with notifications
• Apple Watch / Wear support is iOS-only at the moment (Wear OS planned)

AI WORKOUT PLANNER
Answer seven quick questions about your goal, experience level, schedule, equipment, and any injuries — Google Gemini drafts a complete plan with sessions and exercises in seconds. Generous weekly cap (around ten plans per device per rolling 7 days) means casual planning is free; the cap exists only to keep API costs sustainable.

AI PERFORMANCE INSIGHTS
After every workout, get a short AI-generated feedback note tuned to your recent trends — streak, weekly volume, recent PRs, and overload suggestions accepted. No subscription, no Premium tier — it's there for every user from the first session.

SHARE YOUR WINS
Generate Instagram-story-ready images of your personal records or session recaps. Five bold templates: PR Hero, Recap, Today's Workout, plus a Photo template that uses your own gym photo as backdrop. Posted in one tap.

WHY OFFLINE-FIRST MATTERS
Spotter logs every set instantly using a local Room database — with or without signal. Your gym's basement Wi-Fi blackspot, an airplane workout, a holiday cabin: it all just works. Backup is handled by Android Auto Backup to your Google Drive (system-managed; we cannot read or write your backup), so a fresh phone restores Spotter with everything intact.

PROGRESSIVE OVERLOAD, ACTUALLY
Most gym apps treat warmup and working sets the same. Spotter doesn't. Every exercise has a warmup count and a working count. Rest timers run separately. PRs and weekly volume are computed from working sets only — your numbers are real.

REPLACE OR REORDER MID-SESSION
Find that the cable station is taken? Tap Replace on any exercise card in Today's Workout to swap in a different movement from the catalog. Add or drop sets inline. Apply weight and reps to every set with one tap.

PRIVACY
We collect nothing about you beyond what's needed to render the app — no email, no name, no location, no ad IDs. The only network calls Spotter makes are: (a) Google Gemini for AI plan generation and post-workout insights, and (b) Firebase Remote Config to read one integer (the AI Planner weekly cap value).
