The app does not work as advertised

I've had at least 3 instances where the application fails to keep the computer awake. In all instances I configured iMovie to generate a movie which it stated would take 1 hour. I had configured the time duration to stay awake for 2 hours just to be safe.
I left the macbook pro plugged into the power cord to more than 4 hours. After returning to my macBook, I discovered the laptop had definitely gone to sleep and iMovie still reported 1 hour remaining. I looked at the meter for the sleep no more app & it showed 2 hours.
I was shocked & thought that I misconfigured something. So I repeated the test 2 more times as sure enough I had the same results.

I'm not sure if it's a conflict with iMovie, but it's a repeatable issue.

postpone sleep computer only option not available.

Cant seem to find support page, eitherway wanted to postpone sleep computer only and not postpone display sleep, however if i do that i cant prevent computer from sleeping. Please fix this bug Thanks. otherwise great app :)

Does not work

I have a MacBook Pro running iOS 10.9.4. I am running statistical simulations that take hours to run and therefore need my machine to not sleep. I installed this app to improve my throughput. Unfortunately, the app did not work and I am back to constantly monitoring my Mac so it doesn’t go to sleep.

Can’t explain why it has worked for some and not others. My experience is that this app does not work.
