### 1/5 — No f stop

*2015-10-03, version 1.0*

Won't let me click the f/stop option making it completely useless. Waste of money.

### 1/5 — Just calculator!!

*2014-04-15, version 1.0*

Just calculator!!
Don't need this kind of app.
Save your money and time.
Want my money back.

### 1/5 — Horrible

*2013-08-29, version 1.0*

Written with broken English, and it's a bit glitchy. The calculator is stupid and worthless. It doesn't let you go beyond seconds, and it doesn't let you program in a desired shutter speed.... I want my money back 👎

### 4/5 — works well

*2012-06-18, version 1.0*

but man this app is too pricey.it's a math formula after all. 99 cents would have been enough. I hoped to see pics and examples for that price. Slight rip off....

### 5/5 — Seems to work great and simple to use!

*2012-06-10, version 1.0*

Great app!
