A free program for Android, by Concept2 Inc.

ErgData For PM3 PM4 allows you to connect to older Concept2 PM3/PM4 monitors and view performance data from your device.

The intuitive interface of the app makes it easy to use.

It’s now possible to create and manage an unlimited number of workouts with your own personal data and share them with your friends.

In addition, the ergonomic design of the app allows you to view your data in real time and in more detail than before.

With the performance monitor, you can see more data on your screen, such as the current pace, the number of completed reps, and more.
