Annotation Tool For Mac

I'm really warming up to this app. I've been using Annotate and Monosnap side by side for about two weeks now. Annotate is so much easier on the eyes; and it provides everything I need in my workflow.
- is simple & fast
- has all the tools you need to mark up a screenshot if required (incl. redaction)
- provides the necessary (basic) options for sharing your snaps (Dropbox, email, Twitter, Facebook, and Message; I mostly save to Dropbox or share via Message and email)
- allows you to keep multiple screenshot windows open (love it)
- won't shrink quality/resolution of snaps on Retina systems (an option under Preferences)
- records time-limited GIF movies for quick demos
- won't grab the title of the window you snap (unlike Monosnap; when I have to take many shots in a row, I keep going back to Monosnap so files in my designated Screenshot folder are not just an endless list of files named by date and time, but categorized by window/app snapped)
- won't let you customize the file name (default is eye-mm-dd at
- won't let you specify a custom default Save folder under Preferences (but will remember your last Save location in the app)
- does not have a Timer feature (although the developer is working on it, I believe)
The developer is very responsive, if contacted, and open to suggestions. Their goal seems to be to keep things simple so as not to overwhelm 'nonpower' users — so if you want a ton of customization options, you are not the target audience. However, if you want a nice, quick, reliable screenshot and annotation app, check it out — at $1.99 it's a steal; but at this point, I would even pay $4.99 for it (having the option to keep multiple snaps open at a time alone is worth it for me).
