ErgSpeed is the training log built for indoor rowers. Log every row in seconds, see exactly how you paced it, and watch your fitness grow week by week. SCAN THE MONITOR Take a photo of your Concept2 PM3, PM4, or PM5 results screen and ErgSpeed fills in the rest: distance, time, split, stroke rate, every split, every interval, and every rest. Long workout? Photograph each screen in any order. The scanner tells you when it has them all and asks for another photo if a split is missing. Your photos are saved with the session. LOG IT YOUR WAY Prefer to type? The rowing keypad formats times as you go, so 7124 becomes 7:12.4. Log single-distance, single-time, and Just Row pieces, or distance, time, and variable intervals. Split and watts are calculated for you, and ErgSpeed checks that your splits add up. Record the machine you used, whether it is a RowErg, a WaterRower, or one of your own. SEE HOW YOU REALLY ROWED Every session shows your average split front and center, a pace strip of every split and rest, and a table showing which splits were faster than average. Compare against every past row of the same workout, see your personal best, and jump to your most recent attempt with one tap. YOUR TRAINING AT A GLANCE Home shows this week's meters against your weekly goal, your latest row, and twelve weeks of training as a color grid. Your goal syncs across your devices with iCloud. HISTORY AND FILTERS Every row, grouped by month, with a mini pace strip on each one. Filter by workout type, distance, time piece, split range, stroke rate, machine, and date to find any session fast. CHARTS AND STREAKS Weekly meters, your best 2K over time, and your yearly totals. Keep your streak going week after week. YEAR IN PIXELS Your whole training year in one grid, with each day shaded based on how far you rowed. Share it as an image. POWER PROFILE Your best watts from 1 minute to 1 hour and from 500 meters to 6K, so you know where you are strong and where to focus. RACE PLANNER Pick a distance or time, set a target, and shape your pace: go out hard, settle in, then sprint. See the plan as a chart, save it, and row it live with a segment-by-segment race screen. CALCULATORS Calculate time, split, distance, or watts for any piece. Premium adds training paces, heart rate zones, calories, boat class conversion, and drive ratio. SHARE Turn a session, your Year in Pixels, your Power Profile, or a calculation into a clean image to share. PREMIUM ErgSpeed is free to use.
