Don’t bother, always crashes

Open the app, it crashes. When it does stay open longer that 30 seconds, it’ll crash again as soon as you go into planner.

Literally one of the worst apps I’ve seen in a very long time.

Waste

Crashes all the time. Waste of money

Crashes each time

Great maps if you can access them. Very unreliable.
RCreport a concern

Always crashing

I downloaded it on an iPhone 16 and the app won’t stay open. It crashes constantly. I’ve restarted my phone several times, uninstalled and reinstalled the app a few times as well. It’s totally useless on my phone. It even crashes, just not as frequently, on my tablet. I paid for the app and can’t use it.
