The cat takes up residence in your Mac's menu bar, and he just keeps running!

The cat will run at a speed that depends on the CPU usage on your Mac.
You can see how much the current CPU usage is by looking at the running of the cat.
How about looking at a cat while waiting for a video to be exported or a program to be built?

Back to being a great app

Previous version was sweet — lots of animations to pick from and they looked great in the menu bar. Version 3.0 comes with only 3 animations and on my iMac running High Sierra with 2 monitors it’s just a white box on a black menu bar. Worthless. Hopefully the developer will address the issue. If you have a previous version, I suggest you don’t update.

UPDATE: I wrote the above review on 1/24 and the developer quicky fixed the issue. And a running human was added. Loving this app again.

I love this app, BUT battery notification is needed

Imagine sending out super cute cat-related battery state notifications.
All the other apps of this kind have low/high battery notification, so I hope the developer can find the time and energy to do this. I would definitely consider paying once the functionality side of the app becomes on par with its competitiors.
I already have istat but ould love to keeo this app just for the cats alone...LOVE!

Love it, but lost my purchases

This is one of my favorite apps, very cute, but I lost access to the special runners I paid for with one of the updates. My favorite runner was the octopus and now I'd have to pay a second time in order to get access to it. :( Doesn't seem to be any real way to contact the developer either.

Developer Response ,

Thank you for using my app.
Did you push the restore button bottom of the Runners Store page?
