Right; it's nice that it works out fine for you. The Kindle app would be a good example for me, though, at least back in 2012 (before Marvin release) when I was still attempting to use it. I found the Kindle app on Android distinctly inferior compared to Kindle on iOS. In fact, Kindle was unusable on my previous Android tablet of those days (running 4.0 ICS): the settings buttons were inaccessible. A number of us had the same issue on a variety of Android tablets, but nothing could be done about it. Several support tickets were lodged with Amazon, and a thread on the issue was opened in their support forum, but the issue remained unresolved for many months across a number of Kindle for Android updates. The issue was not so much as
acknowledged by Amazon. After Marvin for iOS appeared, I got p****d off at Amazon for good, gave away all my hardware Kindle devices, deleted the Kindle app from both my iPad and Android tablets, and switched over to Marvin full-time.
I am intensely missing Marvin on Android, as I'm missing the Mailbox app there, the Toodledo app (both essential for me), etc. etc.
