### 1/5 — App feels incomplete. I expected more from HKS.

*2018-09-01*

This app needs to be finished, lots of data (big and only plus), but no customization, runs slow, sample rate needs smoothing (10-15fps feels like), not user friendly or intuitive at all. 

I would gladly give this 5 stars if they just updated the app to run with 2018 expectations, this isn’t the quality I’ve come to except from HKS. Other wise everything else works as advertised.

Aug 29th 2018: Six months later and still no updates. Really upset with this terrible support. This could have been an amazing product. I feel like HKS has given up on this project, and given up on its customers that have pod for it (300$ for the OB-link device!). Starting to lose my faith in HKS’s products. 

Also Changing to two stars because I do appreciate how much information this app can display. I believe it has potential.

ALSO IT DOESNT EVEN FIT THE IPHONE X YET ITS BEEN ALMOST A YEAR
