[Android Apps and Games] Devo7v:
I had a Mi Band and used the MiFit app for the last couple months, but I lost the device. I've ordered a new one and I'm going to start using Gliderun mostly because of the Google Fit integration. While I'm waiting for my package I've been messing around with your app and trying to figure some things out so I'll be ready to go when my new band arrives. Here's some feedback:

The headphone icon opens up the music controls and the audio notifications; music controls/library only works with music stored on the phone, is there any way to integrate this with Google Music? There's only a couple of apps that I've seen do this (specifically GMusicFS), but it would be nice.

On the user screen: for any user input requiring a number (weight, height, goals, etc.) you have a scrolling number which is nice from a UI perspective, but when I have to enter any of these values for the first time, scrolling is very tedious. This is particularly brutal when I'm trying to set up a goal for the first time, I have to scroll all the way from 0 to 8,000. There should be a way to manually input a number using an on-screen keyboard as well. It also looks like the goal is limited to 20,000 steps, theoretically this should be unlimited.

User profile: I have my units set to imperial. When inputting my height for the major intervals you might want to make the height max out at 7-ft just in case. For the minor intervals, you should put the unit next to the number (inches) and I would limit the user to discrete numbers 1 through 12. I'm not sure how you're calculating height, but the way you have it set up it is very hard for a user to input their height in imperial units. For example: I am 6-ft 2-inches, in order to input my height I have to calculate how many hundredths of a foot 2-inches is. So in my case 2/12=.16666. The average person isn't going to do this and is going to give up when you can't just enter 6-ft 2-inches.

The compass UI needs a little work, it isn't quickly evident where north is. I would prefer a more traditional looking compass (maybe something similar to this). Also, for some reason my altitude is always blank.

Synchronize: I have the first three options enabled for Google Fit integration. The app always says disconnected, when I press the synchronize button it changes to connected, but I don't think anything is actually being synced. There should be some sort of progress bar when synchronizing with Google Fit so the user knows it's actually working. In my case I don't think it's working at all. I've enabled the option to download tracked activities from GFit, but nothing ever shows up in the stats.

In the settings, General: I would make an expert section to the settings menu that has to be manually activated and move Optimize track points and Recalculate calories there. Also for any option where you could be deleting or modifying data (everything under the "Other" section) I would have a confirmation dialog box pop up. That way if somebody accidentally presses one of those options they don't completely wipe out all there data.

In the settings, Audio: I would either explain the difference between Audio engine A and B or give the user an option to play example audio. Similar to how you have the option to "Listen to an example" of text-to-speech output in the main android settings.

In the settings, Notification: I think there needs to be a little more configuration for notifications. I really like the way the Notification version of the MiFit app allowed you to set the colors for the LEDs on the Mi Band as well as the number of times it vibrated and the number of times the LED blinked. I know this is a beta version, but I think a little more work needs to be done in this particular area if you want users to switch from the MiFit app. Being able to tell what app I'm getting a notification from just by looking at the band is extremely useful and it's going to make switching hard without it. I don't want to say you should copy the Notification settings screen from the MiFit app, but it has been implemented very well.

Settings: somewhere you need to provide Help information. For most of the options I'm not sure exactly what they're supposed to do, maybe have a ?-button next to the option that the user can press that will pop up a longer description of exactly what the option does.

Any thoughts on providing a dark theme as well? Just something simple where you change the background to black and the text to white, the green color should look good with both a dark and light background.

I saw you have sleep tracking on the list of things to improve upon, really looking forward to that. The MiFit app and Sleep as Android app provide a very clean UI for visualizing your sleep. I would try to implement something similar. I'm sure you've seen it, but this thread might have some hints on how to better pull the sleep data from the MiBand.

I know I wrote a lot, but you have done great work with this app in the short amount of time you've been developing it. I can't wait to see how this app progresses because I think you've got a really good app here. The design looks very good and polished it just needs a few tweaks here and there. Once I get my new Mi Band I'll provide some more feedback.

Keep up the great work. If you want to discuss any of this more I would be more than happy to do so.
