Too bad the sound quality of the voice messages sucks. You'd think Apple would use a higher quality sound file since the message gets deleted in 2 minutes anyway. I'm still using Voxer until it improves.
I want an app that lets me easily edit the data that has already been input into the Health app. For some reason it mistakenly shows that I ran 21 miles in 3 hours while I was actually asleep! So far the only method I have seen that let me edit this is in the health app itself, but I would have to tediously delete hundreds of points of data to do this. I need an app that lets me select a range of data to delete.
I think Reachability was probably designed with the 6 Plus in mind and they just gave it to the 6 too while they were at it. As a 6 Plus user, I find myself using it quite a bit. I can do most things one handed while using it.
Besides optical image stabilization, there's also some pretty big differences in battery life. 24 hours of 3G talk time and 16 days of standby time on the iPhone 6 Plus versus 14 hours of 3G talk time and 10 days of standby time on the iPhone 6 is worth noting.
Apple is planning on making Photos the solution for both consumers and pros. Photography is becoming increasingly important to Apple every year as they improve the quality of their cameras and the software that supports them. The Photos app will incorporate the same type of technology seen in iOS 8 where there is an easy way to make automatic adjustments to photos but also give you access to the finer controls if you want to use them. I don't think we'll lose functionality...
