Incredibly helpful

This app is perfect to have at your fingertips when you’re doing any kind of manual work or play. I’ve learned a ton of knots with this app and it’s easy to pause or step through the animation to fully understand a knot, or to flip to a mirror image of a knot if your instinct is to go left rather than right. The categories are helpful, the info about each knot is indispensable, and it’s easy to add knots to your favorites section for quick reference. I got this so long ago I can’t remember if I paid for it, but if I did, it was worth every penny.

As a bonus: tying my halter top bathing suits with alpine butterflies and sewing the ends down to the back has saved me hundreds of neckaches!

really needs work! ,

Great Isolation Project

Discovered this while creating elements for a backyard playground. The directions and animations are easy to follow, each knot’s information tab is very interesting and, as a solo mom, I appreciated the inclusion of a necktie group. My 10 year old son and I have been knotting our way through Covid-19 isolation; it’s been entertaining, challenging, and extremely useful - we’ve tied everything from placemats and keychains to a seat for a tree swing. After 6 weeks at home I’ve spotted the cat in a variety of harnesses and have memorized the handcuff knot (just in case 😉).

Superb and Indispensable!

I have been using this app for a few years now and I can’t say enough about how awesome it is.

If you think you might be interested in learning more about knots and knot tying; if you kinda like, like, love or can’t live without tying knots...well then this is for you!

Not only do the Grogono’s offer a substantial multitude of knots to get you off and running, they provide excellent commentary on each. The animations illustrate perfectly how to execute the knots. This is really valuable as books, at times, fail miserably in this area-particularly for the more complicated knots.

The value of this app is among the best out there. What a tremendous resource, what a tremendous accomplishment. Bravo fellas!!

It took me a couple years to get around to writing a review for this app and I am more excited about it now than when I purchased it.

Don’t hesitate. BUY THIS APP!
