Great Application

it’s easy to use. Right to the point and uncomplicated. I have been looking for an app like this that’s quick and easy for my busy life style . Had a Doctor appointment and was able to show him my progress. I love it . The Only change I would suggest is the graphing of the data should be displayed horizontally not gust vertically because it compresses the data to much over time and hard to read. I check my A1c
4 Times a day; X 30 days =120 data points. Vertical room on my screen is about 2.5 inches , horizontally it’s about 8.5 inches . Thanks ! Richard

Hi there,

Thank you for taking the time to write your detailed review. We're glad you found the reports useful for your doctor–it's a feature that many users find useful. We're working on some updates soon that should make the graph easier to read with more data.

Needs a little work

Coming from Android’s BG Monitor, I was looking for something equivalent in simplicity but still had the features I was used to and this was the closest I could find. For the most part it works fine but a few minor but deal killers for me.. First is the blood sugar is REQUIRED for an entry, sometimes a BG is not necessary if you are bolusing after a check/bolus/correction. I end up using the previous blood sugar and it messes with the averages displayed on the home screen. Second is the graph, when selecting a blood sugar it only displays the number and date, the time is not included which makes it difficult to target the exact time frame of a high/low trend. Third the contact information doesn’t work, it always displays “Cannot connect to server” at the top every time. There is also no feature for diet other than a notes section on each entry.

Perhaps once the bug with the contact method is fixed and I can get in touch I will change my review. This app has great potential but for me it’s not quite there yet.

So beautifully designed without all the other distractions from other glucose apps

Learning to help navigate a Type 1 diagnosis, and this app is by far the easiest to navigate and see the full picture at a glance. We’ve downloaded and tried several of the top apps to see which is easiest and has all the features we need. Once the developer releases med update (see notes below), we will update to 5 stars. Highly recommend this app for anyone tracking blood glucose, but especially for those newly diagnosed with diabetes.

- all features are free and no annoying ads that take up half the screen
- easy to make entries and tag them for time of day, before/after meals, etc.
- filters make it easy to see trends, and emailed reports have every detail you could want to share with your dr.
- estimates A1C at top of the screen (also free feature)
- can make suggestions to developer within the app...and we got almost an instant response back! :)
- can set reminders throughout the day
- graph option gives clear picture of glucose trends

- can’t specify type of meds unless make a note on the feature (developer says this is coming soon)
- have to click on each entry to see the notes, so no way to see from overview screen which med was taken (hopefully med notes won’t be necessary with update)
- Apple Watch app isn’t functioning
