ErgIntzThe interval app for your Concept2 erg.
Plan the session, and your phone sends it straight to the monitor. Then just row. Every stroke is saved, every personal best is marked — and next time, you'll know if you got faster.
01 — PLAN
Plan it in seconds
Repeats, targets, rests — or let ErgIntz surprise you with a session you haven't done before. Targets come from your own 5 km, so it's always the right effort for you.
02 — ROW
Let the monitor run it
One tap sends it to the PM5. The erg counts you down and times your rests, while your phone shows what matters: pace, watts, rate, and how far ahead of target you are.
03 — BEAT IT
Beat last time
Do the same session again and see it rep by rep against your best. Try to find the sections of the workout where you can improve most.
Progress you can see
Get faster. Watch it happen.
One good session feels great. The same session, month after month, with the line going the right way — that's what keeps you coming back. ErgIntz marks every personal best the moment you set it, and keeps it until you beat it.
4 × 500 m · nine attempts
Every session
Saved properly. Not just a total.
Every rep against your best, how the whole piece compared, the numbers you actually care about, and a mark when it was a best. And underneath, the whole thing stroke by stroke — pace, watts, rate, heart rate.
Head to head
Race your old self.
Pick any two attempts at the same piece and watch them side by side. Drag along the graph to see exactly where you pulled ahead — or where you faded. Heart rate too, if you wear a strap.
Switching?
Bring your history with you.
Already on the Concept2 Logbook? Your workouts and results come straight across, so your historical results follow you and you can compare against old data. Two separate things, both optional: your ErgIntz account backs everything up, and connecting the Logbook afterwards sends every new session back there — and on to Garmin and Strava.
Which ergs
Works with every Concept2 erg.
ErgIntz talks to the PM5 monitor, so it works across the whole Concept2 range — SkiErg, RowErg and BikeErg. Same app, same workouts, whichever machine you're on today. Your 5 km benchmark is kept separately for each, so targets are right on all of them.
Free. All of it.
