The Twiist pump is pretty incredible, with new technology and a clear focus on actually helping type 1 diabetics. However, there are still several issues that need to be addressed, and I hope they do so quickly. For one, I agree with other reviewers about the alarm sounds. They are SO excessively loud and obnoxious and cause real problems in a professional setting with no option to mute or at least turn to vibrate. The pump connection to tide pool is abysmal. I can’t believe they allowed the pump to go to market without ensuring that tide pool was ready to support this system. Even the mobile website doesn’t work, and the desktop is constantly missing data. The issue with the Cleo not adhering to your skin without the use of skintac is another big one. If this is ongoing, they need to include skintac with the refill kits. And finally, the clip. It is completely worthless and doesn’t stay clipped to ANYTHING. It makes wearing the pump pretty obnoxious.

Pros:-I love the pre-meal and workout presets.-I love the option to indicate what glycemic index you’ll be eating. It takes the guesswork out of extended boluses.-I really appreciate being able to adjust the amount of carbs entered into the system after finishing my meal.-The time feature on the bolus screen is awesome!BG target ranges are amazing. I think this will be a game changer, especially for fasting vs. fed BG targets.-I like that you can bolus from your watch.-The weight of the pump is so light compared to the t:slim X2 pump. I love it. The height is comparable to the t:slim X2, and the diameter is about 2/3 the size of the t:slim screen. It fits in my pocket without weighing down my pants. I can also wear it in my bra without there being a visible rectangle like the t:slim.Cons:-Alerts sound like fire alarms; please let us choose the tone, volume, etc.-I wish I could see my glucose reading on my watch without clicking into the Loop icon.-Twiist is not supported on Apple Watch if you want to customize the interface color to anything other than the default colors.-Please create a widget for Twiist on the phone.-The follow app, “Insiight,” does not allow family members to receive glucose alerts for their loved ones.-Would be nice to have time in range reports on app/widget

The app itself works great, my issues arise from the sound when you have urgent lows. It sounds like a fire alarm in your pocket and there is no changing it. It makes being diabetic much more obvious to everyone around you. Additionally, we need a different sensor as the freestyle libre alerts you as low (below 59) but hours later when you check, the actual value at the report time is in the 70s. If these two things can be fixed, then this is an elite system

App works great with the twiist pump, phone and Apple Watch. Incredibly intuitive interface and very reliable. No superfluous clicks like other pump apps. For the first release it’s unbelievably good. Of course, there are lots of ways it could be improved in time. 1. Allow realtime export to Nightscout (so we can use bedside monitors, etc). 2. More customization with alarms… need to be able to snooze, and get additional alerts like “going low soon”. 3. Add widgets, Dynamic Island, and live activities… Those are my top 3 feature requests. I’d love to join a beta for this app. :-) given how early in the development this app is, it’s totally worth a 5 star rating. Hoping it improves in time to be even better.
