Rowly

Rowly turns your iPhone into a rowing tracker for the water. It uses the phone's GPS and motion sensors to measure pace, stroke rate and distance while you row, so you don't need any extra hardware. I built Rowly because there weren't good options for rowers like us. Recording, keeping and sharing your sessions is free, and it will stay that way. FREE • Live pace, stroke rate, distance and time on a large, easy to read display • Pick the fields you want to see, and switch to a high-contrast theme in bright sunlight • Heart rate from a Bluetooth chest strap or your Apple Watch • A logbook with a calendar and your weekly and monthly volume • Fastest 500m and 2k records • Strava upload and GPX export • Back up and restore your whole logbook PREMIUM: UNDERSTAND YOUR ROWING • 500m splits and how even your pacing was • Efficiency: the stroke rate that gives you your best pace, and your distance per stroke • Rhythm and consistency score • Stroke curves from the motion sensors • Technique trends: your distance per stroke at each rate, week by week • All personal records, from 1k to 60 minutes • Replay any session • Stroke and GPS data export (CSV) You can try Premium free for 28 days. Monthly, yearly and lifetime options are available, and every subscription helps me keep improving Rowly. Rowly works for scullers, sweep rowers and coxswains who want a clearer picture of pace, rhythm and efficiency, during and after training. Terms of use: https://rowly.ecvis.nl/terms

Verdict
The clearest difference is iOS requirement: Rowly at 15.0 against Intervals's 18. On price, update cadence, ads and in-app purchases there is nothing between them.
