Looking for beta testers for my app

Hi I'm looking for some people to test out my app. If you're a developer or a designer who works with devs, I'd like your feedback. I'm not looking for landing page critiques, though constructive criticism is welcome. I want you to use my app not scan my landing page. The first 20 people who sign up will receive a steep discount when I go live later this year. Please head over to https://tryvertol.com/ and sign up.

Vertol helps teams maintain and optimize their websites' images.

Feel free to contact me here or twitter (https://twitter.com/iamdwit) with comments or questions.

Thanks ya'll
