## Most critical reviews (5 lowest-rated)

### 1/5 — Uses Too Much Battery and Crashes

*2019-04-03*

Two hour ride, 15% battery use on my phone using background data. 

Crashes every time I look at my RWGPS route list, thus I can't add any routes, Strava routes don't show up at all. Just doesn't work.

### 1/5 — Network Error

*2018-12-05*

I can’t actually use the app is it say “network error” upon launch on both my iPhone and iPad. Pioneer - fix this so the app actually is usable

### 4/5 — Plz, add map data

*2019-05-30*

Using app and ca600 in Korea. But It does not support Korean maps. If you add Korean map, you will be very grateful.

### 5/5 — Amazing Data!!!!

*2019-12-19*

At the end of the day Pioneer give you more accurate data and better analytics than any other power meter out there. This app easily lets you control your computer and upload to any other cycling app out there.

### 5/5 — Hey, Pioneer...

*2019-07-02*

Please could you put some change-log details up that lists what was fixed in each new firmware update?  You used to do that on cyclo-sphere.com, but there is virtually nothing there for the CA600, and neither are you providing any details here in the app updates.  :-(((((
