Great alternative to Caffeine! - I’ve been using the Caffeine app for a few years now to keep my computer awake, but I’ve noticed for quite some time now that it gets a little buggy displaying in the menu bar. I went to go check when it was last updated only to realize that the developer pulled it from the App Store. I was disappointed because Caffeine treated me so well for so long. I came across Amphetamine and, skeptic that it would be as good as Caffeine, decided to try it out. To my surprise, it does exacty what I want and even more. Admittedly, I was extremely disappointed with the default menu bar icon, but there is an option to change it to one of several other icons, including one that looks similar to Caffeine’s coffee cup icon (empty when inactive and full when active). Another nice touch is that you can have the icon dimmed to gray when Amphetamine is inactive. If you are a Caffeine user looking for a much-needed update, definitely give Amphetamine a try.
Doesn - I want to be able to close the lid and carry my mac to a different room or close it to talk to someone for a few minutes without having anything stop. Similar to windows 7 and "When the lid is closed: Do Nothing". The app description says that it cannot handle the use case of keeping the mac alive when closing the lid, so what's the point of even using it? InsomniaX allows you to disable lid sleep.

Simply Amazing - I’m one of those people who like to keep old apps running as long as they run properly. That was the case with Caffeine, an app I found years ago to do exactly what Amphetamine does, except without the preferences. Things have changed since; there’s an app store, and good UI doesn’t mean its lack thereof anymore Amphetamine does exactly what it promises to do. It lets you customize (but on temporary basis!) when your Mac will fall alseep. I was actually a bit worried when I had to right click it to manually activate it. Amazingly enough, the developers gave up an option to switch things around, even the icons. What else could I possibly ask from this app? All I can is this: stunning, a job well done.
Fantastic! - This program is awesome! The triggers feature is incredibly powerful and has all sorts of use cases. I am totally blind and Apple's VoiceOver screen reader compatibility with the app is excellent! Nearly all the elements are clearly labeled and easy to understand. The only problem I've discovered is an unlabeled button at the bottom of each preference screen. It is right next to the help button. VoiceOver simply says the word "button" with no description of its function. I think it's the close button since it seems to dismiss the window when I activate it. If this could be labeled with a useful description like close, it would be even better. Having said that, this is a very minor issue that doesn't impact the usability of the app and would take a minute or two to fix. Keep up the great work.
An essential utility done right - Amphetamine for the Mac is an essential utility done right. It has a clean, straightforward interface. It allows you to use your Mac for live performances, or encoding video, or a jukebox with iTunes, or any other task for which you don’t want the Mac to go to sleep. It offers a good selection of options (stay away indefinately or for a specific amount of time or while a particular application is running) and works flawlessly. I would have happily paid for it, and yet it’s a free utility. I appreciate how with this utility I can have my Mac ordinarily go to sleep quickly when I’m not doing a task that requires the Mac to stay awake, and when I need it to stay awake, I’ll launch Amphetamine. The user forum associated with the App is quite useful. I’m very pleased with Amphetamine.
Almost 5 stars - What is lacking as far as I’m concerned is the ability to customize a start and stop time, even thought it says that it does. The application gives you sets amount of time to be active or it will let you set a custom hours and minutes to be active. What it won’t do is allow you to set a time to become active and a time to shut down. There is a link on the developer’s web site that lets you pull in a version that will all you to do just that, but if you load it and use it, the first time it updates from the app store the ability to set custom start and stop ends. Whenever the developer makes this a standard item in the application I will rerate this program and give it 5 stars.
Great Application and Developer! - Thank you for your hard work and dedication towards the development of this useful App! I can’t imagine working on my MacBook without it now!
