I checked today this app and found cheaper in Japanese app store. Instead of 1200yen it was 850yen. I didnt think long and purchased. It is very easy to use and the most important is, it has multilingual release agreement. In my case I needed in Japanese. It would be good to add assignment release for assistant photographers.
