Ratings and reviews

I think it is pretty standard you would almost certainly need to date your document, perhaps print your name and check boxes - the fact that this app doesn't do those things or even allow you to sign in landscape mode(would be so much easier!) makes it pretty much useless.. ended up having to get another app to do the job. I would give 0 stars because of how annoying the many pop up ads were.

When I sign with a pen for screens and lift the pen off the screen during the signature, small "ink spots" tend to appear when I put the pen back down. The first thing when I put my pen on the screen is a "stain" - it looks untidy and alter the appearance of the signature. I do not have this problem with a ballpoint pen on a paper, which does not leave these 'ink-start marks' when I resume writing. If you correct this, I'll buy Premium immediately because I like your app in general!

DANGER! extremely predatory ads!! app works great, would have been 5 stars but ads are next level predatory, designed to look like system pop up telling you the pdf reader is out of date and directs you to download other applications **edit: as a developer you have control over when where and how ads are displayed. if you don't like the review, fix the issue instead of deflecting blame back to the user. I'm just warning people of a serious security risk posed by the ads in your app
