Does anyone have experience with these devices?
I got one as a gift and it presents quite a bit of data. I'm sure that the physiometrics that the device collects is not that intensive. It does collect body temp and heart rate, and it must have an accelerometer to collect motion data. Somehow it figures out my sleep patterns (rem, deep, light, awakes) and plots that. Anyway, the data seems to match pretty good with reality, I'm, especially impressed with its accuracy in detecting sleep stages - it will capture an afternoon nap, for example. It also syncs data to the mfgs servers where you can configure your data and plots of everything and see trends and all that good stuff.
Now, I have an issue with data usage because the first month the app used 570MB of data. I find it hard to believe the little device sent that much data over its Bluetooth connection, so I am suspicious that the app is either very poorly designed and sends processed data to the servers (although they say it sends raw data), or they are sending other data that they shouldn't. Does that sound like a reasonable amount of data for this application and purpose?
I tried to send them a message about this in their app and after pressing the chevron paper airplane icon, the keyboard went away, but the message seemed to still be sitting there with the chevron at the bottom still. Pressing again does nothing and pressing the text brings up the keyboard to edit again, so I guess they don't want feedback. :rant:

I just bought myself a Fitbit (Charge 3 model) and absolutely love it. The reason I bought that particular model was because it *doesn't* have an in-built GPS receiver. This lack of a feature is seen as a negative by many people but I look at it as a huge positive. Instead it uses the phone's location settings, which can be disabled/fabricated.
Fitbit knows basic details about me (such as age) but that's it. Other than that, all it does is track my activity levels, heart rate, oxygen levels and diet. I don't use it to track my location or collaborate with other users.
It's a small amount of information to give away (which is not personally attributed to me) in order to help maintain my fitness levels.
Over the past month, it has used 30MB of background data and 21MB of foreground data (presumably when the application is active and I'm looking up calorific values of foods, syncing my data etc...).

I set Android to block background data on this app, and since Christmas it still sent 100MB background and 300MB foreground.
Can one set Android to block all mobile data on a single app?
If I go over 500MB data in a billing period I get charged $15 for another block of data. I'm not paying my cell carrier $15/mo for a silly device, especially when I'm not using any of its cloud services.
This is an amazing amount of data. It's 10 times more than all of my other apps combined! email, youtube, etc. 10x more! :scared:
I hope this can be explained and fixed because this is a small company that I was hopeful for. Maybe they just have a bug. Otherwise, I don't trust them. And how does an app get around being blocked?
I was looking at the app manager and it reports this app used 1.9GB memory in the last 3 hours. It also reports almost 8GB mobile data since Nov 3. >:(
