i use Lightshot, you try!
Hi there! I'm using screenshots a lot, mostly to measure sizes, check things up close, and send quick notes to front-end guys. I built Shottr to improve those workflows.
I already published this app here half a year ago, this is a new version rewritten from scratch. It's native, small and blazing fast. It also supports annotations now. Give it a try, I'd love to hear your feedback.
