### 1/5 — Worst software !!!

*2025-06-09*

Keeps losing connection to device - the software feels like it was written by a child with no concept of UX or UI design. 

No Apple Health integration. 

Spams you after starting and after detection with a pop-up to buy the product that you are using (hence, obviously already purchased)

Questionable accuracy, since the quality of the software leaves you questioning the quality of the hardware. 

I’d rather buy a similarly priced or more expensive product.

**Developer response:** We’re sorry to hear about your experience. For issues related to wireless connectivity, please reach out to us directly at service@reflexwireless.com — our support team is happy to assist.

Regarding Apple Health and Google Fit integration, these features are indeed part of our development roadmap, and we are working to include them in future updates.

As for the in-app advertising, we currently display a single popup banner at app startup. That said, we understand your concerns and will explore ways to make the experience less disruptive.

We appreciate your comments and are committed to improving both the hardware and software experience. Thank you again for your feedback.

### 1/5 — Terrible App

*2025-04-19*

This is a terribly designed app. Probably amongst the worst I’ve ever used. 

Yes, it will pair with the ketone breath meter. Yes it will show you ketone concentration in ppm or mmol/L … but it constantly spams you with ads … for the product you are already using! It must be force -quit everytine as it doesn’t maintain Bluetooth connectivity. 

It lacks Apple Health connectivity, which is the biggest flaw. 

I’m considering buying the $350 Lumen breath analyzer instead of this $40 one just because the software is so terrible (par for the course for Asian developers, it seems) and I couldn’t find an alternate software. 

If you’re serious about keto, look elsewhere.
