Hi… Just a couple of suggestions for you:
1. I would love the look and feel to match the OS GUI. I appreciate your designers will throw their coloured pencils in the air at the suggestion, but it would look so much more professional. Just to add insult to injury; I have to be honest that the iOS app really does look horrible, especially the opening nine icons.
2. iOS: Driving the app takes quite a bit of practice to know where you are, where you want to go, and how to get back again. There’s got to be a simpler way? For example: Put the EQ together with the profile selection so all settings are together in one place (icon top-left). Move home key/browser to bottom-left. Move album browser to bottom-right. Move help to settings or home screen.
3. Mac: Rather than a separate Profiles and Settings tabs, have all profiles available for selection in Settings. It’s clunky to install the profile then go over to Settings to select and tweak. Merge About and Activation into one tab – once I’ve activated I don’t really need to see that ever again.
4. Mac: From the Menu Bar drop-down, have the Top 5 or most recent profiles available to select when you mouse-over Built-In, Desktop or Headphones (like Output Device already does). Or better still, your favourite saved profile+EQ settings.
I’m sure I can think of more 😉
