The charge thing isn't that hard to beat. Just plug in your IOS device, it doesn't have to sit on top of the amp, and besides, the slot is angled straight up and down, when it should be angled back to reach the bottom. I use a stand on top of the amp, the slot is poorly designed.
The manual? agreed, it's more of a quick start manual, and includes zero information on using the AMPLIFI app. It's centers only on the unit itself.
