Catastrophic data loss during phone upgrades with no cloud backup despite paid 'Pro' version
"I love the function of this app but hate that every time I upgrade my phone all my data is lost; even with the pro version"
"When I upgraded to a new phone all my data was absolutely gone. No recover options, nothing"
Severely degraded iOS version compared to Android, missing maintenance tracking and other core features
"The Android version is far better and has way more functionality. It is only useful on iOS as an mpg/cost tracker for gas with none of the maintenance records/costs that are on the android"
"The Android version is 7.13 the ios is 1.31. If i cant track maintenance the app us worthless"
