Maybe no one does this by hand anymore…but once in a while, I REALLY need to just do a quick addition of some various final times of VO files for invoicing purposes, and I don’t add so well in Base-6 (remember HS math?).

My search led me to an online site called that has a handy online calculator right there on the screen, or you can download it for your desktop.

But even handier (if you have an iPhone — not sure if there’s an Android version) is the .99-cent app called TimeAdder. I couldn’t seem to find a ready link for this online, but just do a search from your phone for TimeAdder (no space) and you’ll fiind it.  Very simple, easy-to-use interface.

Calc-Zero is another calculator that does the time-addition thing, but it seemed to me to be a bit more complicated app.  TimeAdder does one thing and well.
