Huge scam empty page asking to pay more for upgrade .
BIG SCAM . How does possibly people buy this crappy app and allow to be in the market .
Got Ripped Off!!!
Liked the app at first so I upgraded. Now that I upgraded, I cannot see any of the knots on the app other than the rock climbing ones. Uninstalled and reinstalled, and now it wants me to repurchase the upgrade again! Fix this please!
Mehhh
Not the good, it shows slower less common ways to tie knots
Upgraded, now broken
I upgraded it for the extra 99 cents, an the few knots that do work are great, but the rest have a question mark icon and crash the app. I hope this will be fixed in an upcoming up date
