Owly - Display Sleep Prevention


Open the Mac App Store to buy and download apps.


Say hello to Owly, a cute little fellow who lives in your Mac’s menu bar and does its best to prevent your Mac from automatically sleeping. What this means is that Owly ensures your Mac’s screen never goes dim, no screen savers appear and that your Mac doesn’t enter sleep mode.

By right clicking the Owly icon on the menubar, the app can toggle on/off. When the icon is red, Owly is active and will keep your Mac wide awake. When the icon is black, the app is no longer actively ensuring your Mac doesn’t enter sleep.

Owly is useful for when you want to keep certain information showing on your screen whilst whilst you may not be using the keyboard/mouse actively.

Some examples are:

- Watching a video (non fullscreen mode) and you don’t want your Mac to sleep
- If you are using your screen to view live updating stats
- If you are downloading files and want to be able to monitor the status whilst you may be sat at a distance from your Mac

To access Owly’s Preferences, simply click on the menubar icon. Owly can be customized as follows:

- Set it to launch at login
- The app can be made to appear in the dock
- Adjust the duration for which you want Owly to be active
- Toggle on/off a countdown timer on your menubar for how long Owly will remain active
- Adjust the app to allow your Mac to sleep after a selected battery percentage threshold

We've spent a great deal of time thinking about the details and after using this app for a few days, you'll begin to notice our small yet creative touches. We plan on a very active development cycle, so please spread the word and keep sending us your feedback!

One of my 100% apps — Excellent!

This is one of the few apps that I have running 100% of the time. I find it so convenient to be able to keep my screen on all the time when I am around it, but then click it to screen saver if I leave my office. I used to use the “hot corners” feature of the screen saver for this, but I would unintentionally turn on screen saver, so turned that feature off.

My Mac is my “planner” at work, so it’s helpful to have the screen visible all the time, even if I am not typing or clicking for a while.

I also like that I can have Owly in the bar at the top of the screen without having it take up a spot in the dock.

Excellent App

This app does exactly what it purports to do. My only quibble is that I wish I had full control over the time window - set a time when the app will disable, for example. Otherwise 100% excellent.

Use this all day, every day

Five stars to a great little app that does one thing and does it perfectly. Has more useful features than other similar apps. No conflicts with other OS or other apps I use..
