Clean app and free so far

This is the 4th app I’ve tried, so far and by a landslide it’s far far better than the other top apps. I deleted the others as a total waste of time.
This is clean looking, easy to use, easy to add glucose and food. Only thing I would change is the graph, I would have a line rather than dots.

Would’ve given 5 stars a few months ago

I’ve been using this app for the best part of a year. It’s fantastic. I love how I can keep track of everything via my iPhone and then create reports for my consultant to see.

Here’s why I’ve given it three stars. Before you used to be able to log your glucose, insulin, and carb intake in one go. Now, I have to enter each one individually creating three times the work as before - which is essentially a step backwards in the user interface.

Before I had a black/dark grey background as the white was too bright with the different colours used to represent the glucose, exercise, insulin and carb circles. Now it’s white without the option to change it.

I loved the notifications that would prompt me to take a reading if it had been a while. It’s a shame I no longer get these.

The big downside for me is that I just noticed that the recent update deleted my HBA1C history, cheers!

This App was at its best around May this year, it’s changed for the worst.

Easy to use, annoying bugs, support lacking

I have a subscription to a One Drop meter and testing strips so use this app extensively. It’s easy enough to use and is helping me to get my diabetes back under control, but the most recent changes are baffling and frustrating.

Goals have been added which cannot apparently be customised by the user. This displays an estimated A1C score which is completely different to the estimated A1C in my app health profile. The goal A1C is also changing wildly on a daily basis. Why?

Writing Apple Health data, a fundamental part of this app on an iPhone is hit and miss. Days worth of data will regularly vanish, only to (possibly) reappear a few days later.

The available reports only display in US units so are useless to a UK user as the numbers shown are meaningless to me. As the rest of the app can cope with UK units that seems a poor omission.

I have emailed OneDrop support about all of this several weeks ago yet they haven’t even bothered to reply. As a subscriber to their service I think this is poor.
