What CAN’T you do with your iPhone these days? The phenomenal popularity of Apple’s mobile device and last year’s release of the iPhone developer kit have unleashed a plethora of handy, and some not so handy, applications. Now Israeli company KPL Production Services has released iTC Calc a small, useful application that will help anyone who deals with timecodes in a production or post-production environment.

iTC Calc’s design is clean and simple and looks like your typical Mac calculator, with a few exceptions. Apart from the usual number and mathematical operator keys, in the upper right hand corner of iTC Calc is a dialog box which, when tapped, let’s you choose from 6 standard frame rates of 24, 25, 29.97, 30, 50 and 60 frames per second. So it doesn’t matter if you are working in film or tape, NTSC or PAL, or a combination of both, iTC Calc has you covered.

After choosing your frame rate, you flip back to the calculator screen and are ready to work. To the left of the frame rate dialog you can choose to view your calculations in timecode or frames, very helpful for making quick film to tape or tape to film conversions. A yellow button at the center of the top row of entry keys gives you the ability to make your calculations with an offset.

Tapped the wrong number while entering your code? No problem, iTC Calc has iPhone’s signature “swipe backspace” feature which allows you to erase the last digit entered. More than one wrong number? Just continue swiping until you’ve deleted all the numbers you want removed. It doesn’t end there. Tilt your iPhone into landscape mode (horizontally) and iTC Calc reveals its History and Durations windows.

Entering timecodes can be a mind numbing process so like a paper tape the History window let’s you check and double-check your entries and quickly and clearly view the results. To the right of the History button you’ll find the Durations button. Here, tapping on the TC In, TC Out or Dur buttons transfers the value from the calculator into the respective field. Tap and hold (long tap) one of these buttons and iTC calculates that value. The bottom section of this window calculates TRT, better know as total running time from values in the Dur window. Finally, if you get stuck, there’s a help button to walk you through each of the utility’s functions.

KPL bills iTC Calc as “The perfect companion for any producer, post-production producer, editor, Flame or After Effects artist and anyone else who has to deal with timecodes and frames”. To this I’d add those on set including camera or sound crew, script supervisors or video assist operators. In post, editors and their assistants working in Final Cut Pro, Premiere Pro or any number of other editing packages will find iTC Calc an incredibly helpful addition to their toolkit. You can find iTC Calc and its lighter sibling iTC Light sans History and Durations features in the applications section of the iTunes Store.
