For indoor rowing
Walk the line of rowing machines and rate any athlete from behind. Strokes Per Minute times strokes the same way on an erg as on the water, and speaks the result so nobody has to stop.

An erg session with a squad is a dozen monitors facing a dozen athletes and none of them facing you. The rate drill is at 20, then 24, then 28, and you want to know who is holding it and who is drifting up on the recovery.
Strokes Per Minute lets you rate any machine from wherever you are standing. Watch the handle, tap as it reaches the catch, count the strokes, tap again. The rate is on the screen, and with spoken results on it is in your ear before you have turned to the next erg.
It is the same app rowers and coaches use on the water, so the number means the same thing indoors as it does in the boat. That makes it easy to carry a rate target from the gym to the river and back.
You do not need to see the monitor or stand beside the machine. Watch the handle, tap at the catch, and you have the rate from across the gym.
Turn on spoken results and hold the phone near your ear. The rating is read out the moment it is calculated, so the session keeps moving.
Monitors average over the last stroke. Timing three or more full strokes shows the rhythm the athlete is actually holding, including the rushed recovery they cannot see.
Large numbers in light or dark mode, whichever suits the room at six in the morning.
Concept2, water rowers, slides, or a dynamic erg with no monitor at all. The app only needs you and a tap.
Measurements stay on your device and are never sent to analytics. The only person who sees the number is you.
A rate ladder or a pyramid on the erg, checked without stopping anyone.
Three strokes for quick checks. Raise it to five or six in Settings when you want a longer, steadier sample at low rates.
Behind the machine works best. Tap as the handle reaches the catch position.
Tap on the final catch. Read the rate on the screen or let the app speak it. Continuous mode starts the next reading at the same tap.
Each athlete takes about ten seconds. Twelve ergs, two minutes, no one has stopped rowing.
