### 1/5 — Not working for IPhone 11

*2023-01-15, version 1.5.7*

Not working for iPhone 11 , update not available

### 2/5 — Ct-fit

*2022-05-20*

I can not change theCelsius to Fahrenheit in settings and I have it set to imperial settings

### 2/5 — I don’t get notifications for all my apps

*2021-04-16*

I have two WhatsApp on my phone and I only receive notifications on only whatsapp business. I don’t receive notifications for all my apps. Please upgrade the app so I can get notifications for all my apps on my iPhone.

### 3/5 — Sleep

*2021-03-08, version 1.5.5*

Doesn’t work for broken up sleep patterns

### 2/5 — Add weight?

*2021-03-03, version 1.5.5*

Add A WEIGHT ONE

### 1/5 — Inaccurate and frustrating

*2020-12-29, version 1.5.3*

If you’re interested in tracking your steps forget this app. I did a 5km walk and after looking at my step count it vanished and went back to zero. This has happened over the last 3 days. The date also spontaneously reset itself. Terrible functionality and this reflects badly on the watch suppliers who rely on this app for their customers. Not worth the effort, not worthy of your time.

### 1/5 — Vitals not accurate

*2020-12-28, version 1.5.3*

This watch doesn’t monitor vitals very accurately, I am usually around ~100/60 and the watch had me regularly at ~130/80. I had it on while getting my blood pressure taken in a cuff and I was measured at 109/66 and the watch had me at 129/78. It seems to be accurate with steps but not the rest. But I like that it measures my sleep and reminds me to be active etc... the sleep measurement does not appear to be accurate either, it seems to be a glorified pedometer that shows you your texts and calls and reminds you to stay active. All in all, it is good for me when I’m working at a desk, but I don’t think its worth the money it costs.

### 2/5 — Fair

*2020-12-28, version 1.5.3*

Really disappointing that you cannot add weight lifting as an exercise. It does not give an accurate calorie burn. Very glad this was a gift and I didn’t spend money on it. 
It does make me want a legitimate watch that can accurately monitor heart rate and calorie burn.

### 3/5 — CT FIT SMART WATCH

*2020-12-12*

So far it’s a cool device. I was hoping to a call&text option on here. I figured it was more than just a Fitbit, but it’s just that.

### 5/5 — Great value

*2020-11-06*

This app and the watch are great value. Battery life is good and all the measurements seem to be accurate for this type of device.
The sleep, heart rate and O2 indications update quickly. For BP you have to stop your activity and manually start the process which takes 30 secs +/-. The charger connects via a magnetic contact pad which grabs the cable and orients it with no effort.
