### 3/5 — Constant feedback but not accurate

*2026-08-18, version 1.11.0*

I bought this because it’s a continuous glucose monitor, which is helpful but it’s not completely accurate and its readings as compared to the Polk contest method. Also, when the day changes over, it doesn’t recognize that it’s a new day and you have to shut the app and reopen it before it recognizes. It’s a new day. Although it’s not that accurate in the readings, you can still compare your morning glucose test from the usual method and have an idea of how well you’re doing.

### 3/5 — Sort of disappointed

*2026-08-18, version 1.11.0*

Recently i bought it, back to back sensor is failing. Of course they sent replacement, still not reaching the full 14 days.

### 1/5 — Biosensors fall off very easily

*2026-08-17, version 1.11.0*

I have used 6 biosensors, 2 have fallen off.  The last one fell off about six hours after putting it on.  The quality of the adhesive is very poor.   Will switch to different brand.

### 2/5 — App = Good, Sensor = Bad

*2026-08-17, version 1.11.0*

I started off with a good run, first few sensors did well, and love the app and information that this CGM offers BUT…

This is my first sensor back after a few months of swearing that I would not buy another one after having 3 consecutive sensors fail or fall off after only a week or less. Lingo replaced the first one but after the next two, it wasnt even worth dealing with the hassle and slow replacement turnaround so I just quit using them. 

Well here I am again, and will update this review after my second attempt to use this system so… more to come!

### 5/5 — Easy guide

*2026-08-16, version 1.11.0*

I’ve been using Lingo to help me watch my blood sugar numbers better.  It’s been a game changer in keeping my numbers low!

### 5/5 — Great Buy

*2026-08-16, version 1.11.0*

I really enjoy using the Lingo biosensor. It has helped me learn what foods I should eat and what foods affect my glucose in a negative way.

### 4/5 — Accurate readings when it stays attached.

*2026-08-16, version 1.11.0*

I’ve now used 8 of the 2week sensors. They have been consistently accurate (close match to OneTouch glucose blood testing.) However 3 of the 6 fell off before the sensor expired. Two occurrences were after about a week. One was 2nd day after installation. I’ve now added adhesive CGM covers to hold the sensor in place with better success.

### 4/5 — Change requests

*2026-08-16, version 1.11.0*

The font is too small. The older user needs larger fonts. It could be an option. Also there is a bug in the date display when you’re scrolling left and right in the chart. The date isn’t updating. The log info should be ordered by daytime and the user should have an option to see the data for the whole day at once or filter the log data down so that it shows only the events that pertain to what’s currently visible on the chart. If the scope is 6 hours only show those 6 hours of logs.

### 2/5 — Pretty to look at, but…

*2026-08-16, version 1.11.0*

While it’s colorful eye candy, there isn’t much useful information. Exporting your data just gives you a bunch of dates, times, and numbers - no useful info such as GMI, graphs, average daily glucose, and no associated log entries.  Graph is hard to read and numbers you thought you saw earlier disappear.  The only thing I liked was how easy it was to apply the device; however, the device would disconnect whenever I left the room where my phone was located.  Had to toggle Bluetooth off/on and close/relaunch app to get it to reconnect (sometimes more than once). Plus, because it gives readings every minute, it eats up the phone battery.  Not a fan.

### 3/5 — Weak connections

*2026-08-15, version 1.11.0*

The device consistently looses bluetooth connectivity.  This happens several times a day.  I have my phone with me all the time . So it’s not distance related.  Just bad connectivity.
