The SmartRow App (together with the SmartRow-conversion) will turn your WaterRower into a lab grade ergometer. It will not only show you power, distance, work-per-stroke, calories etc., it will show you each force-curve, heart rate graph and much, much more! It keeps track of your workouts, and even shows you well-known fitness metrics like 'Watts-per-Beat' and 'Watts-per-Kilogram'. It even syncs your workout data with Apple Health. This is the best training tool you can invest in—after hiring a coach, of course!

You do not see your own body change. You look at it every day, and every day it looks the same. HYM fixes that with one habit: one photo a day, your weight beside it. WHAT YOU DO Open the app. Take today's photo. Enter your weight, one tap per half pound, no keyboard. That is the whole thing, and it takes fifteen seconds. WHAT YOU GET • A wall of every day you tracked, newest first • Your weight over time, next to the goal you set • Before and after, side by side, from your own photos • Day count, days tracked, weeks left on your target WHAT IT IS NOT There is no streak to break. No six rules to check off. No community feed. HYM asks for one photo and nothing else, if you miss a day, nothing is lost and nothing scolds you. YOUR PHOTOS They live on your phone first, and the app works without an account. Sign in and they are backed up to a private EU bucket that refuses unsigned access. Delete a photo and the copy is erased too. Delete your account and everything goes, server, storage and phone. HYM PRO Free shows the last 15 days. HYM Pro shows everything you have tracked. Nothing is ever deleted: if you subscribe six months from now, every older day comes back intact. • Weekly = $8.99 • Yearly = $59.99 Payment is charged to your Apple Account at confirmation of purchase. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the period. Manage or cancel in your Apple Account settings.
