Ive been using this app for a few years now and it has been perfect for what I need. I have tried similar apps in the past, but all have paled in comparison. That said, I upgraded my phone in Nov 2015 and lost all of my data (maintenance history, gas log, notes, everything). Perhaps I am naive, but it didnt even occur to me that this wasnt backing up to the cloud, which seems to be a standard practice for most apps these days. Unfortunately, Ill have to find a different maintenance app that can withstand the test of time...I simply cannot afford to re-enter my maintenance history every 2-3 years.
