I have had Type 1 diabetes for 20 years and this app is a complete life saver. It takes the stress out of working out dosing - all you have to do it enter your current sugar level and how many carbs you’re going to eat and it tells you how much insulin to take.

Since using this app my sugar levels rarely go above 10mmol, it helps me manage hypos (as most diabetics know it’s easy to over indulge when you have a hypo!!).

Thank you to the developers of this app for making it, you’ve changed my life!! 😊

Thank you for your kind review!

Not as good as hoped

I have used this for a week or so but don’t think it is working for me. Predictions are way off, it doesn’t seem to take exercise into consideration during exercise so it is not for me. I also find it far too fiddly when inputting data and it requires a lot of data. Not sure how others says it tells them how much your dose should be as you have to enter carb ratio yourself. Unfortunately I paid for 3 month advanced option but will not be using it.

Thanks for your feedback - there are some incorrect items here.

The onboarding tool helps you set an initial carb ratio if you choose 'I have fixed doses' or 'I have fixed doses plus corrections'. If you have your carb ratio already, that's fine too. PredictBGL will help you refine the ratio either way.

Exercise data **of course** is included in the calculations. Not sure why you're saying this.

All diabetes tools require a lot of data to setup. But after that, entering a BGL (if you don't have a Dexcom or FreeStyle Libre) and Carbs is a pretty low bar.

Please contact for help setting it up properly.

Wouldn't allow sign up

Thought that the app could prove to be useful, so downloaded it, opened it and tried to sign up. Completed all fields, pressed sign up and got what I presume was an iPad generated alert message, which I had to ok. Wasn't sure if it was because I had used the password somewhere else, so changed the password to one that was unique. Tried to sign up again, this time got app generated message stating that the user already exists.
Ok, back to start, went for login this time and used the first set of credentials. Now get the alert box when I press login, can't work out how to get passed this, .... Deleting
