### 2/5 — Bought brand new 9 and it tells me a watch 8 or newer not detected.

*2024-07-07*

Bought brand new 9 and it tells me a watch 8 or newer not detected.

**Developer response:** Hi,

To fix your issue, please ensure you are wearing your watch to bed while sleeping to make sure the watch is able to take an accurate temperature measurement. In addition please make sure you have a sleep schedule set up, as this is the only way the watch is able to take a temperature reading. You can find out how to do that by looking at the screenshots in the App Store for this app. You can also locate it in the Health App or the Clock app.

Please reach out to us if you have any other questions as our number one priority is customer satisfaction.

### 1/5 — Waste of money

*2024-07-05*

I have an Apple 8 Watch and this app doesn’t recognize that there is one connected to the app. I have tried 10-15 tips submitted by other Apple Watch users to get it working but nothing changes. No support on the app side of the equation, either

**Developer response:** Hi Phillipa,

We always respond to customer requests in a timely matter. Unfortunately we don’t have any emails or requests from you.

### 2/5 — Doesn’t fully work

*2024-06-04*

Doesn’t detect my Apple Watch Ultra 2 so I don’t get wrist temperature data

**Developer response:** Hello, please ensure that you are utilizing the “bedtime” feature found inside the Clock app or Health app. All it will take is one nights sleep for Temperature readings to take place. For more information please see the screenshots above. 
If this works please consider revising your review or email us at Info@EngineeredEssentials.com for more help.

### 5/5 — Simple but useful

*2024-06-02*

Easy to use, simple but insightful information on one screen.

### 5/5 — Awesome Alert

*2023-11-23*

It gave me an alert that I was showing signs of being sick, giving me the ample time needed to get rest and get hydrated.

### 5/5 — Pretty accurate

*2023-11-23*

Pretty accurate and useful

### 5/5 — Amazing

*2023-11-11*

Extremely accurate, got a notification and alert that vitals were trending high and got sick a few days later, this was super impressive to me as I’ve tried other apps and none have even come close to impressing me as this one, 10/10 would recommend 👌🏼👍🏼

### 5/5 — New update is nice

*2023-09-24*

New update added lots of nice features. Developer seems responsive.

### 2/5 — Could be so much better with small changes.

*2023-07-31*

Bought this app on a whim as I saw someone recommend it online.

The premise is good however the UI needs some work. We should be able to review the heart rate and heat data on the same graph and correlate the measurements. I should also not have to turn my phone sideways to see the date properly, it’s only showing the month. Not being able to change to Celsius or dd/mm is also a big let down.

A few small changes and this app would be well worth the money. Right now however it needs some work.

**Developer response:** Hi, as of 1.1.5 we have implemented a toggle inside of the apps settings screen. The toggle will convert all values into Celsius. We are also implementing new features that take your other suggestions into account, and will soon be releasing them. 

We hope you like the conversion feature! 
Please email us through the contact form also in the settings screen for any future questions you may have. 

Thanks!

### 1/5 — Does not work with Series 8

*2023-07-30*

Does not recognize version of Apple Watch for some reason.

**Developer response:** Hi, please make sure you wear your watch to sleep and have a sleep schedule set up. This is so that the watch knows to measure your temperature. Apple has designed the Watch only take readings at night when there are no outside influences that can influence the accuracy of readings. Please follow up once you’ve worn the watch for a few nights with a sleep schedule set up and report back! Looking forward to hear how it went.

And please consider updating your review once you have done that. 

Thanks
