Accessibility Comments

VoiceOver appears to read all the interface elements perfectly. The only issues I have noticed are a few unlabeled buttons in the tutorial and in some setting screens.


The app is fully accessible with VoiceOver and is easy to navigate and use.

Other Comments

I've been searching for an application to override the default sleep behavior in Mac OS X. This program appears to be the best and most customizable.

Amphetamine is best and most customizable.

This appears to be a very significant update. While my triggers migrated successfully, I am having trouble making new triggers and activating them. For example, it appears now that you can only choose one type of criterion for a trigger--so I couldn't say, while this wifi network is connected and this app is running, for example. Please, someone prove me wrong!

Also, when you select the "While file is downloading" option from the menu bar, you are presented with a standard file open dialog, but the dialog is not clear as to why it is there. If anyone else is confused by this as I first was, please respond and I'll add that to the list of things to email the developer about.

Thanks for any further commenting on this topic,

You can specify multiple conditions for a trigger. Select the item you want from the menu button and check the checkbox to enable it. If necessary, customize the settings to your liking. Now go back to the list of conditions and select something else. Check the checkbox and customize the second condition. Repeat until you're satisfied. Your trigger will now fire when all conditions you've specified are met.

I'm not sure about the while downloading option. I'll write to the developer about that as well.

I just stumbled upon this app in the Mac App Store yesterday. I'm really impressed with it's features and the level of VoiceOver accessibility. I once tried caffeine but quickly got rid of it. I simply wasn't happy with it. This is far superior to what Caffeine was. Perhaps Caffeine has been updated since I last tried it, but Amphetamine far exceeds my expectations so I have no need to look further.
