Knots 3D is a reference app from Nynix LLC. It teaches users how to tie many types of knots using 3D animations. The current Google Play listing shows more than 220 knots, over 1 million downloads, and a 4.9-star rating from more than 28,000 reviews.
The app is useful for people who fish, camp, sail, climb, or work with ropes. It can also help Scouts and beginners who want to learn a knot by watching each step instead of reading a flat picture.
Knots 3D is a paid app. The current Google Play price is listed as $5.99, with no ads, subscriptions, or in-app purchases.
Space and Security Info
The developer’s app information lists the size at about 258 MB. This is much larger than a simple text reference app because it contains a large library of 3D knot models and animations.
The app is designed to be self-contained. Google Play says no internet or other permissions are required, so the main knot lessons can be used without an internet connection.
The current Google Play Data Safety section says that the developer reports no data collected and no data shared with third parties. This is a strong point for users who want a reference app that does not need account access or online data services.
Cache growth was not available as a verified number. The final storage space can also vary slightly by Android phone and app version.
Real Device Test Run
I cannot honestly say I completed a two-day physical test of Knots 3D on a Redmi phone. I do not have measured results for battery loss, phone temperature, scrolling speed, or visual glitches.
I would not make up battery percentages or heating results and call them real test findings. The public app information confirms that the app uses 3D animations and allows users to rotate and control them, but this is not the same as a Redmi test.
A proper two-day test should check several knot animations, 360-degree rotation, zooming, animation speed, screen changes, and longer sessions. It should also measure battery use and phone temperature before and after use.
Best Features to Use
- 3D Knot Models: The app includes 222 unique knots according to the current Play Store listing. Users can rotate each knot in 360 degrees to see how the rope moves.
- Step Animation: A knot can tie itself on the screen through an animation. You can pause it or change the speed when a step is difficult to follow.
- Finger Control: You can move your finger across the animation to go forward or backward. This lets you study one part of a knot without restarting the whole lesson.
- Knot Search: Knots can be found by category, name, common synonym, or ABOK number. This makes it easier to find a specific knot when you already know its name.
- Light and Dark Mode: The app supports both light and dark themes. It also works in portrait and landscape modes and allows full-screen viewing.
Alternative Apps
Knots 360 Pro is another paid 3D knot app with about 191 knots and adjustable animations, and it is listed at $3.99. Knots by Pro Knot costs $1.99 and focuses on 70 fishing and rope knots with animated instructions. Knots 3D costs more, but it offers a much larger collection with 222 knots and 360-degree controls.

Knots 3D is a focused learning tool for anyone who wants to understand how knots are tied. The 3D rotation, adjustable animations, offline use, and large knot library make it useful, but the $5.99 price and roughly 258 MB size may be too much for someone who only needs a few simple knots.
