Hi everyone,
Since there's actually a lack of cinematography apps on Android, I developed my on, called quite basically "Cine Tool". You can download it for free here : http://goo.gl/EgF6m
And you can see it on the application website.
For now, it's actually mor for assistant camera : you can calculate the depth of fiel, the shutter, the time-lapse and how much memory space or film length you'll need for a given duration, but there's still not a sun position function or an exposition adjustement one, though it will come in future versions.
Don't hesite to send me your opinion !
