Countdown Timer Pro
“Create highly customizable countdown timer overlays with ease using Countdown Timer Pro, a completely free macOS app.” There are several other apps like Countdown Timer Pro available for macOS, but it is very well executed and free. What more could one wish for? Mac App Store Countdown Timer Pro
BookPlayer
“A wonderful player for your M4B/M4A/MP3 based audiobooks.” In addition to an eBook Reader I was looking for a dedicated audiobook player. I think, I've found it. BookPlayer leaves nothing to be desired. If you want, you can view its source code on GitHub, or support the developer with a Pro subscription, which then enables features like iCloud Sync and standalone Playback on the Apple Watch. BTW I use the ancient looking, but still working Audiobook Builder to convert countless separate mp3 files to one combined M4B audiobook. BookPlayer App Store
BarCuts
“A Surprisingly Useful macOS Shortcuts Launcher.” "A macOS menu bar app that surfaces your relevant Shortcuts workflows when you need them. "Tag" workflows to an application, and when that app is in front, BarCuts will show its tagged workflows in a menu, ready for you to access." - nothing to add. One thing done right. Very useful, as Carlo's other apps. (I heavily rely on Actions For Obsidian for my Daily Notes in Obsidian.) actions.work/barcuts/
