How to Tie Knots

Amazingly aggressive advertising. Is it even allowed to have these popups? Seems more like malware than other. Too bad the knots were good. But 100MB for a big ad? No.

Good app. Very useful and clear. BUT the ads are out of control, every few clicks causes another ad to popup, taking up the entire screen. Fix this and than ill recommend it. I should have to pay to get rid of ads. I can just forget your app and use the internet, just sayin

Great step by step instruction. Ads are annoying and too frequent.

Useful app. Live the 3D. Would rate higher but the pop up adds annoying.

Graphics are really good, like a stop motion clip of each knot, really cool

Idea for app is great but it's so slow and has lags (probably through a lot of video's weight). Font is unreadable and to decorative. Moreover ads into are horrible, they're everywhere, cover app site, during using app shows pop up with only 'ok' button to 5*rate - that shows why this app is rate so high...
