Cleanshot X is a screenshot capture and annotation tool for macOS. I use it multiple times per day.
From the website:
Give your friends the superpower of productivity!
We are sure you know someone who could benefit from a great screen capture tool. Show your friends that you care by giving them CleanShot.For every gift purchased we will plant a tree.
After completing the purchase, you will get a link that you can deliver to your friend.
I don't know if you can gift a copy to yourself with the same email address.
doesnt macOS also have a shortcut key like windows' windows key+shift+S
