WHAT YOU GET
ββββββββββββββββββββ
β’ Strength score β your lifts are scored against real strength standards for your bodyweight and gender. One 0β100 score for overall strength, plus a level for every exercise from Beginner to Elite.
β’ Fast workout logging β tap, type, done. No friction between you and the bar.
β’ Personal record tracking β automatic PR detection for every lift, every rep range. See exactly when you broke a record and by how much.
β’ Post-workout summary β after every session, see your score move, the records you set, and which muscle groups you hit.
β’ Progress charts β visualize strength gains over weeks and months. Track top-set weight, estimated 1RM, and total volume per exercise. The 30-day view is free; 90-day and all-time graphs are part of Pro.
β’ Muscle heatmap β a full-body map showing which muscle groups you train the most, by strength level and training volume. Bodyweight exercises count toward volume too. Part of Pro.
β’ Challenges & medals β arm a challenge before your workout, complete it in a single session, and earn its medal. Collect every one to unlock a bonus card.
β’ Achievement cards β unlock cards as you hit milestones, then equip one as your dashboard background.
β’ Body weight log β record bodyweight over time and see how your strength scales with it.
β’ Workout history β every session saved. Filter by week, date range, or view everything, then tap any workout to review every set and rep.
β’ Custom exercises β add your own movements. Barbell, dumbbell, machine, bodyweight β track anything.
β’ Metric or imperial β switch units anytime. Your data stays consistent.
β’ Export & backup β your data, your control. Export everything to a single file.

PRIVACY-FIRST DESIGN
ββββββββββββββββββββ
Monolith is offline-first. Your workouts, body stats, and profile are stored only on your device. We don't run analytics, advertising, tracking, or crash-reporting SDKs. We don't have servers. We can't see your data because we never receive it.
The only network call the app makes is to validate the optional one-time premium upgrade through Google Play Billing and RevenueCat. Nothing else leaves your phone.
