FNDMobile is a 99-cent iPhone app from bambooapps that lets you track the development times of your favorite films (and all their many variations) using a simple and intuitive interface.

Now you can store, in one convenient package, all your knowledge and experience about film development, complete with times and dilutions.

FND also helps you in the development process, thanks to its built-in timer that suggests when you should agitate your development tank (following your instructions).

You can purchase the app from iTunes.
