### 2/5 — Desperately needs updating.

*2026-08-14, version 3.5.0*

This app definitely needs an update. It has gotten so it doesn’t upload the readings from my monitor. It was great two YEARS AGO but now not so much. It hasn’t synced with the monitor in over a month. HORRIBLE!

### 3/5 — App froze

*2026-08-11, version 3.5.0*

When confirm access to apple health data, it immediately freezes, and stays frozen after reboot.

### 1/5 — Sign in, Forgot Password no longer works

*2026-08-07, version 3.5.0*

Used to work. Doesn’t anymore. No Testing of the App or has the App been discontinued?

### 1/5 — Need to be better

*2026-08-07, version 3.5.0*

This should either have multiple profiles or the ability to delete data points.

### 2/5 — App works but health sync is hit or miss

*2026-08-06, version 3.5.0*

I like the app for keeping an eye on my blood glucose and have it synced to my apple Health app to keep everything in one place but I alway seem to have issues getting the data from the contour app to Apple health

### 1/5 — App not updated in over a year

*2026-08-03, version 3.5.0*

App throws errors every time I try to sign in. I’ve deleted the app restarted the phone, and reinstalled the app. Same issue. Worthless as it is.

### 1/5 — Requires an account

*2026-07-31, version 3.5.0*

There’s no need for an app like this to require an account. All the data could be easily stored and processed on-device without sharing our data with yet ANOTHER corporation. Aside from that, you can’t paste the password from a password manager into the field when signing up, so two strikes before I even get INTO the app.

### 1/5 — Garbage app

*2026-07-31, version 3.5.0*

How can an app be this bad.  Please just remove from app store and quit wasting people's time.

### 1/5 — Bluetooth does not connect

*2026-07-08, version 3.5.0*

I followed the instructions to connect the device to the app. Despite the simple instructions to connect, it did not locate my device. Will delete this app since there’s no point to use it.

### 2/5 — Poor syncing and tracking

*2026-07-08, version 3.5.0*

I downloaded the app 5 days ago and so far it stopped syncing twice. The first time I had to delete it and reinstall. Today I just give up on it working at all and I’ll track old school with pen and paper!
