## Most critical reviews (3 lowest-rated)

### 1/5 — great until iOS 9

*2015-09-29, version 1.6.3*

Do NOT upgrade to iOS 9.  This app used to work great until then.  Now it just crashes upon launch.

### 1/5 — Waste of time

*2013-09-11, version 1.6.2*

Bought the accessory needed for my Canon camera. Once attached the app recognized it and I can confirm the shutter functions do work. However 2 different yet compatible cameras to the accessory do not receive GPS info; what I ultimately purchased it for. Several emails to support have gone unanswered. So the accessory is going back and the app deleted.

### 4/5 — As advertised

*2013-03-19, version 1.1*

Functions as advertised. I was somewhat hesitant to purchase the hardware because of the poor grammar in the product description and the fact that no one has reviewed it. The device arrive promptly from Japan and it was a breeze to setup. It works reliably and has more features and is cheaper then blueSLR. I would recommend it to others. I give it four stars instead of 5 because I wished the connection to the camera was more flexible and therefore less likely to break, but no problems so far.
