Performance improvements and bug fixes

User reviews

Watch for low blood sugars

Good, the machine algorithm gets off tho every time though with no way to adjust leaving the user with severely low blood sugars.

Great app - some serious flaws

I’ve been using the iLet for more than half a year and the pump is wonderful. I use the freestyle cgm as well. It’s a shame that I can no longer view my glucose as a widget or on my Apple Watch now that I use the iLet. There is no option for that. Also, the app disconnects all the time even if I leave the app to run in the background. My circle can never see my glucose unless I have the app open. Of course the iLet is life changing and it’s also pretty new so I won’t give it 3 stars, but life could be so much better with these things s fixed

Life changing

Best app ever

Absolutely Life Changing!

I have had the I-Let Pump for about a month now and has been a night and day difference for my sugar! I’ve had Diabetes for about 9 years now (since i was 10) and I have been very bad with my sugar and taking injections. My A1C stayed above 10 ever since i can remember. Throwing up everyday, sleeping all day, couldn’t keep weight etc. Ever since I have gotten the pump my sugar hasn’t been above 250! I feel so much better, gaining weight again, and feeling like I live my life again without diabetes holding me back. The app works amazing with the Freestyle Libre 3 plus and with my iphone. I do wish i there was an option to silence one or the other alarms so they aren’t both going off from the pump device and my phone. Keep coming out with updates for the app and the pump please, this product has change my life for the better! God bless whoever is still reading this, and happy 4th!!

The most part the pump is great

For the most part this works fairly well I just wish you would let me make dosing decisions or male announcements or the pump had a screen recorder on it for somebody who was blind.
