When it wouldn’t work

I was going crazy? I thought the United States made you go away because you were a Canadian app. you’re so simple and easy to use. I’ve loved you for years.

Want It For Multiple Users

I think this App is great!! Makes simple Bolus calculations easy. I just wish I could save multiple users all at the same time. (Please add this into your next update!)

Nice but a pain

Every time it updates it resets everything to zero and to the Canadian standard! Please find away so the settings carry over!

Response from developer

Hi there, I think I have finally fixed this glitch that some users have experienced, so sorry that's happened, but we should be good now with 2.5.1.

What happened?

Was working fine, then, my stored numbers were gone. Also, now it won’t let me put USA for home. Stuck on Canada? I updated the app and reset and the bugs they said were fixed were def not fixed. Same issue.
