### 1/5 — No luck

*2022-07-27*

Paid for the app to try to use for Zwift running. Drops the connection within 30 seconds every time. Tried troubleshooting, no luck.

### 2/5 — Mr

*2021-05-06, version 1.1*

Tried the free version for the 5 mins it allows then had to buy . Worked fine for five ( free ) mins and worked once only since . I’m using the Apple TV 4K for the zwift run app , says it’s connected but doesn’t work when I set the speed . Load of rubbish that doesn’t work consistently....... shame as it could have been just what I needed .

### 1/5 — Spend as much time off the elliptical as on

*2020-06-11*

Even though I purchased the app it drops every few minutes.  I didn’t have to get off the elliptical and try and get things reconnected. In the meantime it took me seven minutes to go .18 miles as I was trying to finish up a 3 mile run.I turned off all the other Bluetooth devices around me to make sure there was no interference. The app has no built in way to contact anyone for any troubleshooting advice.

**Developer response:** Hi, there may be multiple reasons for disconnection. Did you tried to switch off then switch on Bluetooth before start? If you need some help, you can contact us per mail 'contact@bipr.fr'

### 3/5 — Having some issues

*2019-12-16, version 1.0*

I downloaded this app on my iPhone, paid to unlock and all works well.
On my iPad though, it works in limited free mode. When it reaches the limit, it stops and when I proceed to pay (again) to remove the time limit I receive an on screen display that says “we’ve received your request, please wait a moment” but nothing happens and I am returned to the previous screen.
