About ErgIntz
ErgIntz turns a Concept2 erg into a proper interval machine. Build a workout on your phone, send it to the PM5 over Bluetooth, and row it with live targets, countdowns, and spoken cues — no button-pressing on the monitor mid-piece. BUILD REAL WORKOUTS • Distance, time, and calorie intervals, with fixed or open-ended rest • Repeats and variable structures — 6×500m with 1:00 rest, pyramids, tabatas • Targets as a pace, as watts, or as a percentage of your 5 km power • Import a workout straight from a screenshot ROW WITH THE NUMBERS THAT MATTER • Live pace, power, stroke rate, and heart rate from the PM5 and your heart-rate monitor • Work and rest countdowns, with audio cues so the phone can stay on the floor • Pace or watts everywhere — your choice, applied across the whole app • Every colour graded against your 5 km best, so intensity reads at a glance KEEP EVERY SESSION • Full history with splits, laps, and per-interval averages • Personal bests per workout • A share card for the sessions worth showing CONNECTED, IF YOU WANT • An account is just an email address — no password, and the app works without one • Connect your Concept2 Logbook and every session lands there automatically — and Concept2 forwards it on to Garmin Connect and Strava • Join a club to row shared workouts and see who turned up on the boards ErgIntz works with the Concept2 Performance Monitor 5 (PM5) on RowErg, SkiErg, and BikeErg, connecting over Bluetooth. Bluetooth heart-rate monitors are supported.
What’s new
Version 1.5.0 · Updated October 27, 2026
A club's live screen can now show several figures for each rower at once: distance, watts, watts per kilo, smart average watts, pace and time. You choose which to show and which one the list leads by, and the lead's unit is set on the club workout and when you share a result link. Watts per kilo are shown for every rider who has a weight set. A rower who dropped out, stopped or finished stays on the live screen with their result, also after the live window has closed. A finish that was not saved says so. The live graph keeps its zero line with whoever is still rowing, and stays one size on every screen. A rest longer than 9:55 now works: the erg times it as an interval of its own, and the app moves on to it on time, shows your power while you row through it and records it as a rest. If iOS ends the app while you row, the session is offered back for two hours, an open warm-up included. The app also no longer works in the background for a screen nobody can see, which is what got it ended. The screen only stays awake while a session runs. START and its warm-up options are one green button, always on one line. An erg that answers Offline is loaded again once you sit still, and a stop is no longer counted as the end of a segment. An open group goes to the erg 25 intervals at a time, and no two rests can sit side by side in the builder. A new workout starts with an empty name. Results from a Logbook import and the comparison screens are more careful about what counts as a best.
