A fast, private, offline workout tracker for Android. Log every set, build and schedule routines, and watch your strength and BMI trend over time — no account, no cloud, no ads. Your training lives on your phone.
- Download the APK (Android 7.0+)
- Visit the site for an overview and install steps
Open the downloaded file on your phone, allow installing from unknown sources if prompted, and tap Install. Updates install right over an older version — your routines, history and custom exercises are kept.
-
Section-based live logger — your workout flows one section at a time (warm-up first), keeping focus on the exercise you're on while the rest stay tucked into a clean list. Move between sections with Forward / Back. Starting a workout while one's in progress lets you resume it or start fresh.
-
Log workouts fast — track weight × reps, bodyweight, time, and distance. Each set shows your previous session's numbers for reference, with a traffic-light cue (green = beating last time, amber = matching, red = below). Quick-step weight buttons (+1.25 / +2.5 / +5 kg) build on the weight you already lifted, plus an inline plate calculator. A W / N / D / F set-type guide (Warmup / Normal / Drop / Failure) sits right where you log.
-
1000+ exercises — a built-in library of over a thousand movements, including 120+ stretching and mobility exercises. Filter by muscle group, search by name, and add your own custom moves anytime.
-
Routines & schedule — build reusable routines organised into sections (Warm Up / Mobility / Primary / Secondary / Static Stretch) and pin them to weekdays. Start a planned session in one tap from the home screen.
-
Rest timer that buzzes — auto-starts after a logged set with sensible defaults, and vibrates and notifies you when it's time for the next set — even with the phone locked.
-
Strength progress — estimated-1RM trend lines per exercise, automatic personal records (heaviest weight and best est. 1RM), and a fractional muscle-balance breakdown that surfaces neglected areas.
-
BMI tracking — add your height and weight and plot your BMI over time against the healthy range, updated whenever you log a new weight.
-
Streaks & badges — a forgiving weekly-target streak (you pick 1–7 workouts/week) plus milestone and consistency badges to keep momentum.
-
History — a chronological session log with a contribution heatmap.
-
Share routines — export all your data to a file, and import a friend's routines — merged in safely without touching your own.
-
Private & offline — no login, no servers, no tracking. Everything is stored on your device, and you own a one-tap backup file (Profile → Export data). Units are kilograms.
Kasrat collects no personal information beyond a display name and optional height/weight, and never connects to a server. To move your data to another device, use Profile → Export data and import the JSON backup on the new device.
It's a self-contained app built with Capacitor — all data lives on-device. The full product and design notes are in design.md.
