"title": "Index",
"body": "I really enjoy this app and get a lot of use out of the knots that they allow you learn how to tie, if I had to make a compliant it would be that a top left index drop down be added so I can quickly brows all available knots under specific category's without the pictures in a much more condensed roughly like 12 or 14 point font so that with a scroll or two you’ve gone through half of the available knots, something that had a drop down for each category would really help ease of app navigation, besides that I would say they did a real bang up job on this , with an index I’d give it 5/5",

"body": "Most knot tiring apps lean on 3d but always need internet access to stream video witch dose no good in the field. This app is offline and strait forward but easy to follow. I would suggest just a little more info on where and when to use one knot over another. Some examples to give context to give reason if you will.",

"body": "The app gives you a photo of the finished with no feature to search for a note that you’re looking for the lighting is uneven over the different nuts and tells you step one, but leave you hanging there could have been a couple more steps to actually show them not be made, but this app does not have a feature moving feature of the rope is all static photographs and only one or two images to get to complete the knot.",

"title": "Buggy and subscription locked",
"body": "There are only seven knots available for free and even those are interrupted by full-page video ads. The knots are given as photos of each step but the button to advance past step 1 did not work, so I could only see the first step. I would consider paying for a high quality knot app, but not a monthly subscription and not for such a buggy app. You could buy a good knot app- or a book- for the price of one or two months of this subscription.",
