## What is iLet App?

The iLet App is part of the iLet Bionic Pancreas system, an automated insulin delivery system that reduces the need to make decisions about your diabetes management – because it makes the decisions for you. The iLet needs only one number – your weight.

After startup, the iLet learns about YOU – your basal insulin needs, how to correct you to target, and how much insulin you need for your meals. The goal of the iLet is to reduce the burden of diabetes management.

The iLet Bionic Pancreas is the only insulin delivery system that makes 100% of your dosing decisions – so you don’t have to.

-No carb counting*
Instead of carb counting everything on your plate, the iLet just needs an estimate of the carbs in your meal — Usual for me, More or Less.

-No corrections
The iLet makes the corrections for you. If you’re trending high, it will automatically give you more insulin to bring you back in range. If you’re trending low, it will reduce your current insulin dosage.

-Dosing decisions made for you
The “Bionic” part of the iLet that communicates with your CGM and makes all of the insulin dosing decisions—no carb counting, no correction factors, no adjustments.

-No pre-set basal rate
iLet learns your needs and automatically adjusts your basal rate on the go.

-Simple setup
No settings are required to be entered or adjusted—the iLet system only needs your weight to get started.

-Small but mighty
Small (1.9” x 3.6” x 0.6”), lightweight and easy to put in your pocket or clip to your clothing.

-Talks to your CGM
Your iLet device communicates directly with your Dexcom CGM or FreeStyle Libre 3 Plus sensor to know where your glucose is headed.

-Water resistant
If you drop your iLet in water—no problem! It’s protected in up to 12 feet of water for up to 30 minutes.

-iLet App
The iLet App displays data from your iLet home screen in real time so you can view your current glucose, trend, notifications, and other important information directly on your phone. It also supports data synchronization, reports and updates for your iLet and allows you to share your data with your healthcare provider.

-Create your Bionic Circle
With the Bionic Circle App, up to 10 friends and family can remotely monitor you to see CGM values, meal announcements, and insulin doses and to receive alerts (Urgent Low / Urgent / Low Soon / Low/High / No Data).

Please note that any changes made to your iLet therapy settings should be done under the guidance and supervision of a qualified healthcare professional. Before making any adjustments, it is important to consult with your doctor to ensure that the changes are appropriate for your individual needs and health status.

### 1/5 — Pairing Issues

*2026-02-05*

Terrible Pump. I cant lie it never connects to the dexcom and when it does. It never brings my sugar down I definitely recommend NOT getting this

### 5/5 — A HUGE Mental Relief for Diabetes Management

*2026-01-30*

The ILet has been a great solution for me. It truly relieves the mental pressure that comes with diabetes management. No more constant carb counting, injecting, waiting for highs, adjusting insulin, or fighting lows. Since using it, my blood sugar levels have been much more stable, and day-to-day management feels significantly easier and less stressful.

One area of opportunity would be reporting. As a pilot, I need to generate monthly glucose reports for FAA medical certification, and it would be extremely helpful if the app allowed downloading or exporting reports by selected month to share directly with medical examiners.

Overall, this is an excellent system that has made a meaningful difference in my quality of life.

### 5/5 — I love this pump!

*2026-01-17*

I have been using iLet for a month & love it and the app!  I love that I can call Customer Support, the nurse educator can see my data remotely, they have been very helpful in pointing out where I made decisions that are good and not the best way to do things!  My Endo can also access my data remotely!

### 3/5 — New

*2026-01-01*

Too new for a full review. Seems to be doing its job after 2 days. App needs to have the “fork” as most people manipulate their phones. Super inconvenient to do this one very important task on the pump!

### 2/5 — Worst insulin pump

*2025-10-07*

iLet pretends that you can return this terrible pump but then when you try they evade your calls and say you need to try it for a few months.  It is so slow to correct high blood sugars in the 280’s but this trashy company wants me to just let the pump learn and eventually the blood sugars might come down. I’m not interested in being the test dummy for this garbage pump while it jacks up my A1c. And because they refuse to let me return it and I live in America, now I won’t be able to get a different insulin pump for years. Well hopefully the Twiist insulin pump comes out and is covered by pharmacy benefits instead of DME benefits.

### 4/5 — Update app

*2025-06-25*

Update the app more so have new things to see

### 4/5 — Update

*2025-04-23*

Why is my app saying “update firmware” but when I click on it, it says it’s already updated?

### 3/5 — I’ve got some small problems

*2025-03-30*

Since updating this application of the phone goes idle for any period of time, the application seems to stop, other phones connected to the circle no longer receive updates unless the main phone is unlocked and the application is opened again, I cannot seem to find a correction for this, and I’m assuming that it’s just part of the update

### 1/5 — Do more please

*2025-02-03*

Would like to have some control of the pump. Like meal announcements from the app . Maybe I’m doing it wrong. Pump works great..

### 4/5 — Nice application with room for improvement

*2024-12-12*

very clean interface and functioning application. No complaints. Only a desire for a future update that allows meal announcements to be made from the phone. Please make this a reality.
