As you're all more than likely aware, the Massive Dev Chart is an invaluable collection of development combinations and timings for literally hundreds of films and developers.
It's been a while coming, but we now have a portable offline mobile application specifically designed for Android devices, which allows smart-searching of films and developers, results displayed for small, medium and large formats and extended information all at your finger tips.
It's available now in the Android marketplace, just search for "Massive Dev Chart". All feedback welcome.
