Test Inertia before launch

Before you sign up

Inertia is a companion app, not a standalone tracker. Two things have to be true:

• You already have an intervals.icu account. Inertia reads the training data already sitting in your intervals.icu account — it doesn't record activities or replace it. If you don't have an account there yet, create one first.
• Your activities sync to intervals.icu directly from your device (Garmin, Wahoo, Coros, a head unit, etc.), not relayed through Strava. Activities that reach intervals.icu only via a Strava connection arrive without the underlying data streams Inertia needs, so most of the app's screens won't have anything to show for them.

If either of those isn't the case yet, it's worth fixing before testing — you'll get a lot more out of the beta.
