This app worked really well until I decided to get fancy and create an account so the app would be able to back up my plan. When I did, the app would whir, and whir, and whir...telling me to wait (for hours) while it backed my plans up to the cloud. I contacted customer support, and while they helped me find a work-around (use the app only while in airplane mode) they have not yet released an update to address this bug.
As for ease of use, I find it to be a really intuitive app. Of course I can think of some mods that would make things easier to use (like selecting all of a particular SFG plants on a plan at once to modify configurations), but overall I like the app. It just doesnt get more than 2 stars until they fix this annoying bug!
