The story

Sixteen years chasing hundredths

Henrique Rodrigues swam the 200 individual medley for Brazil at two Olympic Games. He is a Pan American champion: gold in Toronto 2015 with a Games record of 1:57.06, the third fastest time in the world that year, and a World Championship finalist in Kazan.

Sixteen years of high performance taught him where speed really comes from. Technique is the part of the sport that matters most, and the part almost no swimmer gets honest feedback on. SwimLytic is that experience turned into software: film a lap, and the kind of frame-by-frame analysis he relied on as a professional runs right on your phone, pointing out exactly what to fix.

“Races are won in technique.”

FAQ

Common questions

How does SwimLytic analyze my swimming?

It maps 33 body landmarks in every sampled frame of your video and scores 8 technique metrics: entry, catch, pull, recovery, rotation, kick, head position and breathing. The analysis runs entirely on your phone.

Does my video get uploaded anywhere?

No. Your video never leaves your device. Analysis runs on-device and only the resulting numbers, the scores and angles, are saved to your account.

What do I need to film a good analysis?

A phone, a side view of the swimmer, and 8 to 20 seconds of swimming with the full body in frame. Film in landscape, at about waist height, and follow the swimmer with a smooth pan.

Which strokes are supported?

Freestyle is the calibrated stroke today. Backstroke, breaststroke, butterfly and underwater are available in the app and are being calibrated with real footage.

Do I need any extra hardware or sensors?

No. A regular phone camera is enough. There are no wearables, no waterproof case requirements beyond your own filming setup, and no subscription hardware.

What does the score mean?

Scores run 0 to 100 across 8 metrics, combined into an overall score and a tier: Bronze, Silver from 60, Gold from 75 and Diamond from 90. The report shows which metrics cost you the most and the drills that fix them.

How much does SwimLytic cost?

SwimLytic is free while in beta. Paid plans will come later, and beta testers will be told before anything changes.

Who built SwimLytic?

Henrique Rodrigues, a two-time Olympian and Pan American champion in the 200 individual medley, built it after sixteen years in high performance swimming.
