This is a test build. It is not on Google Play, it talks to the test server rather than the real one, and the sessions you row on it stay there — they are not sent to your Concept2 Logbook.

Installing it
- Tap Download above, on the phone itself.
- Open the downloaded file. Android will say it cannot install apps from this source — that is normal for anything not from Play. Tap Settings on that prompt and allow it for your browser, then go back and tap install.
- Open ErgIntz next. It will ask for Nearby devices so it can find your PM5 over Bluetooth. On older Android it asks for Location instead — that is the same permission wearing a different name, and the app never looks at where you are.
- Sign in with your email. You get a six-digit code by mail; there is no password.
It installs beside anything else called ErgIntz rather than replacing it, so a real one on the same phone is left alone.
If something goes wrong
The app keeps a technical log of what it does with the erg, and on this build it sends that log so it can be read without the phone in the room. It holds no heart rate, no email address and no sign-in code. You can turn it off under Settings → Diagnostics; it is on to begin with because that is the whole reason for a test build.
