I downloaded the iOS version, but couldn't proceed with the settings as it was asking for my insulin intake and doesn't allow you to skip. It looks like this is for people on insulin injections
I used to use 'Easy Diabetes' on my phone, and logged everything. Took over my life!
Now I have a pump I use my pump handset to do all my working out, and it stores the data, so I'm not tempted by a separate app any more.
I did like the Easy Diabetes app, but it did rather fuel my obsession for meticulous logging.... which I suspect would have applied whichever app I had gone for!
