have been using Jolt for years, both personally and professionally. I would constantly run into an issue with needing my computer to stay awake and working on a task, but I would also need to divide my attention to complete something else. I would come back from my other task to find my work and progress halted or restarted completely. This was a problem I needed a solution to because I am not someone who wants to sit by idly to watch my computer finish a task. Enter Jolt. Ever since downloading this, I am able confidently allow my computer to complete tasks without having to monitor. I can turn on Jolt for an hour or two (however long is needed) and leave the house to run an errand or even for the day and know that my computer will be completing the task for the designated amount of time and then sill sleep and rest once the timeframe has expired. I have recommended this to friends, family, and colleagues whenever I have had the opportunity. This app is a must have!

I once used another app named simply Caffeine that worked excellent. After I excepted this last update that apple had on the mac book pro, the older app stopped working properly. I was kind of hesitant to down load this one at first, but after reading a few reviews, I figured I had nothing to lose. I have only used it today, but so far it's just like the previous one that I used. I open the app and select a drop down for how ever long I want to have the computer open without going into sleep mode. It actually gives me an option for longer periods of time, than the previous app I used to use. So far it's a five star in my opinion. Def worth downloading and giving it a try. Works great!! No problems so far and I've had it open for more than 4 hours at a time. Hope my review helps others that also may have been hesitant as I once was.

There are no ads in this product. After your first use, the developers of this free tool show you their other tools, as part of a screen that thanks you for downloading. That’s not an “ad” in my book (NO 3rd parties paying for placement, NO tracking, etc). Thats just the dev saying, “Hey, I took time to build this useful tool, and you got it for free. I also make other software.” If you don’t want to check it out, you close the window, and that’s literally it. Never pops up again. Never “shows ads” while running. People just don’t pay attention to whats actually on their screen.Thank you for the fantastic tool, devs. Works great, has robust options, and does NOT have ads :)

First annoyance is that it takes 3 clicks/taps to turn it on (i.e., tap menu bar icon, tap "start jolt for" then tap then time, which is always forever in my case). How about tap the icon in the menu bar once to turn it on or off with the current time setting?Second annoyance is this weird dialog that comes up every time I turn it off (only takes 2 taps/clicks to turn it off). The dialog says omething like, "are you still having troubles with your Mac sleeping? if so, we are here to support you...". So clicking the "No" (or yes) button on that dialog makes the 3rd tap/click to shut it off.Other than those minor things it works as expected. I would prefer the "on" icon to just be a full cup, without the BIG BRIGHT RED bit, but meh. No big deal.
