Frequently asked questions
Why is CarFlow not public on Google Play?
CarFlow ships through a closed test. After buying a key you open 48-hour download access for your Gmail on Get download access.
What if I change phones?
Tap Log out in the app on the old phone, then activate on the new one. Each key can move 2 times in 365 days. Customers moving from CarTube get one extra free move.
Is the app removed after 48 hours?
No. 48 hours is the window to install from Google Play. The installed app keeps working; open access again to reinstall.
Do CarTube keys work?
Yes. CarTube keys move to CarFlow; enter your old key in the CarFlow app.
Can I get a refund?
Keys are digital and activate instantly, so there is no refund after activation. Contact support before activating if your car does not work.
Will it work in my car?
Any car with Android Auto (wired or wireless) and an Android 9+ phone. If unsure, ask support before buying.
