How long have I dreamed about such an application! Thank you, it saved a lot of nerve cells during the development of websites! Sometimes customers even do not know how to make screenshots and try to say edits by phone
Amazingly simple and convenient
Thank you!
Thank you for the product you created. Very cool stuff. As a project manager, I especially share the pain with edits and gigabytes of screenshots
Nice product!
I've been using it for several months and it's really handy for an IT company. Now we don't send screenshots to each other and fix the website way faster! Thanks!!!
