Common Questions

Does it really work when I have no bars?

Yes. Any info you've looked at recently stays on your phone. You can also change things and save them — MZS holds your changes and sends them when you're back online.

Can I add my race results after the race?

Yeah. Log results anytime. The app just needs to know you finished and where you finished.

How do I cancel my subscription?

Sign in, go to settings, then billing. You can cancel anytime. No penalties. But tell us why — your feedback helps us get better.

Is there a free plan?

Yes. One car, 10 sponsors, full access to results. Upgrade to add more cars or unlock reports and setup sheets.

How do I install it on my phone?

Sign in on your phone, then look for the install prompt at the bottom. Tap it, and it installs just like any other app. No App Store needed.
