Velolytica

Serious cycling analytics that stay on your phone. Import your rides, see power, training load, zones, and fitness — no account, no upload, no subscription.

Velolytica is serious cycling analytics that runs entirely on your iPhone. Import the rides you already have, and see the training numbers competitive cyclists actually look for — no account, no upload, no subscription.

BRING THE RIDES YOU ALREADY HAVE Drop in files from a head unit, Apple Health, or a Strava bulk export. Velolytica keeps your ride names, detects sport types, dedupes repeats, and turns the archive into useful history. • FIT, GPX, TCX, ZIP, GZ, and Apple Health • Import a whole bulk export at once

THE TRAINING NUMBERS SERIOUS CYCLISTS LOOK FOR • Normalized Power, TSS, Intensity Factor, and W′ balance on every ride • Power curve from five-second sprints to hour-long efforts, tracked against your own best rides • Personal-record detection for key durations, with FTP and CP context when your history supports it • Seven power zones and five heart-rate zones, with zone balance across your training week • Climb detection, splits, and pedaling dynamics when your sensors provide them • A plain-language verdict for every ride

FITNESS OVER TIME Fitness, fatigue, and form are built automatically from your ride history, so you can see whether you are getting fresher or digging a hole.

EFFORT ON THE MAP See exactly where the watts, speed, gradient, or heart rate changed along your route, painted by effort.

RECORD WHEN YOU NEED TO Use Velolytica as a phone-based ride recorder with GPS and Bluetooth power, heart-rate, and cadence sensors, then finish straight into the same analysis as your imported rides.

YOUR RIDES STAY YOURS Ride files are imported and analyzed on-device. There is no login and no server round trip, your original files can be exported again, and the App Store privacy posture is simple: Data Not Collected. Velolytica reads workouts, heart rate, VO₂max, and weight from Apple Health only to enrich imported rides, and writes nothing back.

Works fully offline. The brain, not the feed.
