I've been on the road for a few days and while shooting we've been roughing in some potential VO's to show the client.
I didn't realize it right away but my iPad doesn't have a built-in timer to time VO's to 60 & 30 seconds.
Here are two FREE timers I found that I dig:
1. Timer Z
Timer Z has an optional alarm when time is up and has a stress-inducing optional visual aid which frankly I love watching. It also has a great history log of times which you can email if you need to.
LabTimer can run 4 timers simultaneously which is more helpful than you'd think. Plus seeing the duration of past attempts is handy.
