### 1/5 — Common problem with Bluetooth not working

*2023-02-02, version 1.31*

App does not work at all can’t find the sensor or connect to it or anything 
Common problem with these kits it looks like on bluetooth no problems with Cobb but I have seen lots of issues with the bluetooth not connecting or not downloading on some kinds of iPhones can’t look for the sensor and the people that can find the sensor can’t connect to it or it just doesn’t show anything

### 2/5 — Not working iOS 13.4.1

*2020-05-12, version 1.3*

Takes absolutely forever for the app to pull up my flex fuel kit through bluetooth and when it does no matter how many times I hit live data it won’t ever show anything. It worked before but not anymore.

### 1/5 — It won’t dowload or work

*2017-12-17, version 1.0*

On here, the download circle just freezes. Eventually, it pops up on my home screen. When I turned on the car, nothing happened. I followed the same steps as I would on a Samsung & nothing. It’s such a bummer. If I wanted to invest in my own Delicious Tuning, I’d have to give up my iPhone 8 and spend extra for a phone. Come on Delicious Tuning! We need you on the iPhones!
