Taper: Muscle & Fat Tracker

Most trackers just store your numbers. Taper tells you what they mean.

Is your bulk building muscle or fat? Is your cut costing you strength? Taper reads your bodyweight, your lifts, and your waist together and gives you a straight answer.

KNOW IF IT'S WORKING • Body-composition verdict: Building muscle, losing fat, or spinning your wheels, graded from your data • Works from your weight and lifts alone: A waist measurement sharpens it, but it's never required • Per-muscle progression on a live body map: What's growing, what's stalling • Fair matchups: Only compares lifts done the same way, so your PRs are real • Anomaly detection: Flags outlier sessions so a fluke day doesn't skew your trends

SET A GOAL, SEE THE FINISH LINE • Set a weight or waist goal and get a real ETA; a live countdown to the day you'll hit it, based on your recent pace • Trends for weight, waist, and every lift, charted over time • Progress photos with side-by-side before/after compare

LOG FAST, PROGRESS AUTOMATICALLY • Quick set logger: Supersets, tags, rest timer, plate calculator • Auto-progression: Always know your next target • Templates, consistency streaks, and deload tracking • Log weight, waist, and soreness; auto-import weigh-ins from Apple Health • Live Activity + Home Screen widgets: Your verdict, goal, and streak at a glance

YOURS, AND PRIVATE • Local-first. No account required, your data stays on your device • Optional iCloud or Google Drive sync • Free export and import. Your data is never locked in
