### 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.

### 4/5 — New IOS

*2024-10-01*

It seems like my app can’t read my pump and display my blood sugar and other info in real time at the moment. Not sure if it’s because of the new OS cause it was fine up until this morning.

### 4/5 — ILet App. Latest update made many improvements!

*2024-07-02, version 2.0.1*

So, this is a review about the app (not the device). The latest update is much more useful than the last version. I love the similar look as the Dexcom app, as well as the added quick look at insulin dosage as well as device battery life and insulin units in a numerical value.

If I could add anything it would be to be able to set more of your x and y numerical values as well as more alerts on your phone (iLet volume is to low). Also I have yet to be able to use or see any history beyond the past 24 hours. It looks like that is more a placeholder for a future version.

In summary, great update! App works well, eagerly anticipating more updates.

*Side note - I love the iLet device so far! Keep pushing this awesome technology ahead guys! And add me a snack button.

### 4/5 — Easy to configure and pair with iPhone

*2024-03-23, version 1.3.1*

I just got the iLet and set up training, thankfully over Zoom so it's only a little over a week away. The trainer called to set the appointment up and to let me know to unbox the device, charge it, download and install the app, and update the firmware. The update gave it Dexcom G7 support, BTW. 

This all just plain worked worked, and having the Qi charger is SO much better than struggling at night with my previous Tandem pumps outdated micro-USB plug that never wanted to fit when I had my glasses off! 

It might be nice if this app came with Apple Watch support, maybe to add meal info. I already get my blood sugar levels on the Dexcom Apple Watch app.

My only criticism is that the text on the screen is pretty dim. I found that you can rather wake up button twice (if it's locked you see three .gt signs showing brightness on the unlock slider) to make it a little brighter, but it's still dim. But it seems to look brighter when you have another light source angled on it. I could not find a way just to set an acceptable brightness setting without an external light source.  
After training I'll update or post a review about the actual results of using the pump. Of course, only after properly following the pumps learning process. 
A friend of mines daughter has been using hers for a month or two now, and he said in a few weeks it made a world of difference for her. And it's still learning. 

Someone criticized the infusion set, saying it got yanked out. Hey, that's not the apps fault, and it happens. The Accusoft infusion sets I used with the Tandem got yanked out if I bumped into something the wrong way, and just plain fell off in hot and humid weather unless I added an extra adhesive around it. So did my CGM.

### 4/5 — Trying it’s hardest.

*2024-02-21*

Hello!!! I’m a pretty young diabetic. I’ve been using the I-Let since october. This has helped SO MUCH. I have been very stressed because of my diabetes, causing my mental health to deteriorate. With the I-Let? I have felt better then ever. 

All I have to say is, it’s very easy to rip out. I ripped it out at school, whole day I was high and my ketones rose to 1.6. I wish there was more measures to keep this from happening. Through out the whole time i’ve used it, it’s ripped out 6 times.

### 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

### 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..

### 1/5 — Stopped working

*2024-10-23*

I haven’t received a reading in the last 2 days, it just clocks

### 1/5 — Not ready for prime time.

*2024-01-01*

The iLet decides when to give insulin based upon your meal announcements and what it has learned about your habits. In theory, you never have to count carbs or worry about how much insulin to give.

The corollary is that you can’t make any decisions. You can’t decide you need more, or less, insulin. There is no way to make this machine work as a standard insulin pump.

After following the instructions, I found the iLet simply wasn’t doing the job. There were many nights when my blood sugar sat above 300 for hours. But you can’t argue with the iLet - if it “thinks” you have enough insulin, you’re expected to simply wait until your body agrees.

Betabionics doesn’t have a backup plan for what to do if this machine doesn’t work for you. At first they told me to wait and be patient while my glucose levels were dangerously high. Allow the iLet to learn. I’ve had Type-1 diabetes for more than 40 years, and have never been under such poor control as with the iLet. 

If pressed enough they’ll advise that you unhook the pump for a while and use syringes or to change your infusion set. But ultimately if the iLet doesn’t work for you, you’re out of luck. 

I wanted the iLet to work. I like the concept. But it’s just not ready. It now sits in my desk drawer, unusable. For anyone considering purchasing an iLet, consider a Tandem or Medtronic or Omnipod instead - something with a track record.

**Developer response:** Hello, 
The iLet is designed to learn each individual user and makes 100% of the dosing decisions so the user doesn’t have to. When following training guidelines, the iLet algorithms will learn to react over time to the user’s highs and lows, based on meal announcements and glucose levels. Because the iLet works so differently from other systems, training from a certified iLet trainer is important so that the user know how best to help the iLet learn their insulin needs. Please give us a call at 1-855-745-3800 and we can help with questions or troubleshooting with the iLet.

### 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.

### 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!

### 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

### 3/5 — Weak app

*2024-08-08*

The Home Screen provides no information about insulin on board (which would be helpful to prepare for potential hypos prior to exercising). This missing info is inconsistent with the app providing average insulin used for meals and basal on the Report screen. Not providing pump users with current insulin on board on the Home Screen makes the iLet difficult to use when exercising. 

The Report Screen frequently crashes: it displays the “spinning sun” entry screen but never advances from there.  The only fix is to quit the app and try again. 

The “overview” graphs the Report screen don’t provide  x-axis labels, so it’s virtually impossible to interpret the times associated with the glucose values provided. 

Scrolling through the daily graphs of glucose levels and making sense of the tiny bar charts that display meal boluses is difficult because a) the graphs don’t show what size of meal was chosen (usual, more than usual, less than usual) and b) the pump algorithm doesn’t give the user any control over managing the size of these boluses anyway. I guess you might get insight about how long prior to a meal to announce it?

In summary, the lack of info in the app makes it difficult for people who want to adjust the timing of their meal announcements and for people to plan how to maintain glucose control while exercising. As currently designed  the app is a missed opportunity to inform users who need more involvement with glucose control other than announcing carb intake.

### 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?

### 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!

### 5/5 — Bionic Pancreas

*2024-09-27*

iLet app is super innovative and helpful! Amazing technology!

### 5/5 — ILet is an incredible device…..

*2024-09-24*

The ILet pump and its app are both incredible and easy to use. I have personally lived with T1D since 1982 and have been using various pumps since August 2000 (Disetronic, Animas, Medtronic, Omnipod, Tandem and now ILet).
This pump is what I have been dreaming about and hoping to have for years. 
It is accurate and so easy to use and benefit from. 
I am looking forward to the future with new options with Beta Bionics and ILet. 
Anyone that wants accuracy and ease of use and not having to think about diabetes all day long, so get with Beta Bionics and ILet.

### 5/5 — Chill Mode

*2024-07-16*

Not sure about some of the bad experiences I’m reading about on here…

My a1c has been low to mid 6’s since I can remember. I’ve always just been on shots. I never wanted to use a pump bc of all the hassle and my numbers were always good. I tried iLet bc I was frustrated with my “rage bolusing” and I was always fighting lows after fighting highs. 

The ilet hasn’t changed my A1c’s (6.0-6.6 since starting in sept 2023), but it’s allowed me to “let go” a little and not worry constantly about my glucose levels.

Again, this is the only pump I’ve ever wanted to try bc it looked so easy to use with not a lot of work. And I’m really glad I took the leap!

The new app is way better than the old one. I can look at my phone to see if/when I announced and what my level is. Nice features.

### 5/5 — iLet is a relief

*2024-07-16*

I have had diabetes for over 35 years and I’ve tried most of the insulin pumps on the market. I have felt a little burned out recently and when I found out about the iLet and how it makes 100% of the insulin dosing decisions for me, I decided I needed to give it a try. This is a game changer for me. Over the last two weeks I’ve been over 80% time in range and have had far less low blood sugars than I have in the past. The iLet app is great. since my desire was to not have to fiddle with my pump as often, the app now allows me to see what my pump is delivering and what my trends are without even looking at my device. It mirrors everything I wanna see. Now I just wish they would come out with a way to announce a meal on the ILET app. Please please please.

### 5/5 — Awesome app

*2024-07-16*

Love the app colors and display screen. Helps to see this so I don’t have to take the pump out from my belt or pocket so I can see what my sugar is and if I announced a meal. It’s great how quick the advancements with this pump happen. Also love that I can just email my report to my provider right from the app!

### 5/5 — Wow that was easy

*2024-07-16*

Diabetes can be hard. ILet makes it a whole lot easier.

### 5/5 — Amazing App!!!

*2024-07-16*

Clear, concise, easy to read with all the data you need to live a healthy life!!!
