Simple elegance & efficiency

Been using this app through its various iterations for a few years now and have been pleased with its performance. Really like not having to deal with a Preferences page and being able to handle that aspect through the icon drop down menu. It does what I need it to do and makes my life easier by eliminating the annoyance of having to deal with screen timeouts.

Works. Good design.

Works well. Doesn’t even need a Preferences page because all of the functionality is in the menu. You can also toggle it on and off by just clicking the icon. However it keeps asking me to leave a review, which is the only reason I am leaving this review. If it doesn’t make it stop reminding me, I’ll soon be using a different app…

Developer Response ,

Dear KevinThr, thanks for you feedback. The ask-for-a-review behaviour was not intended and I fixed this in the current update (Version 2.0.1). It would be great if you could reconsider your review. Kind regards, Martin

Works great

When caffine failed on me in Mojave I was incredibly annoyed but a quick search brought me this and it works perfectly.
