ScreenSnip

Drag to capture part of the screen, then annotate with text and drawing tools, or pin the shot above every other window. It runs OCR to pull out text, and it can read a Wi-Fi QR code and join that network.

ScreenSnip is made by Alpha Tembo in Harare. It is for Mac. Try it free for 3 days, then one activation code runs it on one Mac. US$12 once.

US$12 for one Mac, after a 3-day trial.
