Shottr - Free Mac Screen Capture Utility App

Shottr is a free Mac screenshot application that supports full-screen screenshots, customisations with drawing tools and annotations, multiple file formats including PNG and JPEG, and powerful editing tools. Additionally, it has an easy-to-use interface and allows users to share their screenshots on social media or via email.

I used this app almost every day. Extremely useful and does the job with style and panache.
