Awesome  E90dread  5 star

It's money well spent!


Great tool  Sanchezable  5 star

Love using the app. Updates I hope to see. A gauge for fuel economy (miles per gallon). Add more of the steering wheel controls in the app for easier control. Also a eco map to maximize fuel economy, similar to eco and sport on modern BMWs.


App needs updating  msafar95  2 star

This app needs an overhaul from top to bottom. The UI is very unfriendly. For the price of the app, it'd be nice fnthe developers atleast made the app look good

AMAZING  Ruben casas  5 star

Best option out there. Everyone loves it, except all the v8 guys (mustang)i blow pass! This defines, on the fly tuning


Fraud  Shh73  1 star

This app is a joke. Charged me over $30. Already called my credit card company and for a non payment and fraud by the app creator. Don't buy it!!!!


Major flaw  leCarbone  1 star

Needs security. There is nothing to stop someone else from connecting to your car and changing crucial settings causing damage.


Plug and play out of the box  GT640  5 star

As with everything BMS makes, this is amazing. Works perfectly after a five minute install. Updated firmware on first login. This would have cost thousands a few years ago! Love you guys!


Good app, some flaws  Tr1p13a  4 star

Good app for data logging. No longer need computer jb4 app after. Yet there are some bugs and the 0-60 and 1/4 mile are no longer a feature. If they fix those then I would give it 5 stars.

If you run JB4 this is a no brainer.


Great app  FreshRal1art  5 star
