dotTech: Knots 3D Review

On December 16, 2013, in Blog, Reviews, by Administrator

A great review of Knots 3D from app review website dotTech:


Overall, I was very impressed with this app. There is a huge variety of knots here, and they are well-organized. The animated 3D diagrams make it really easy to see how a knot comes together, even if there are multiple strands involved.

As a history nerd, I particularly enjoyed the descriptions that come along with each knot. Having some background about how the knots were used and devised in centuries past is actually very helpful when you are trying to figure out what knot it best for a certain situation

Knots 3D International Mentions

On December 16, 2013, in Blog, Knots, Reviews, by Administrator

We are thrilled that Knots 3D is being used all around the world!  We came across great reviews this week from websites located in the Czech Republic, Russia and Germany and found that Knots 3D is a required app for a college in Australia!

The first review is from Yachtmeni, a popular Czech Yachting website and Blog.


Aplikace je k dispozici pro operační systémy iOS i Android a stojí něco málo přes 20 Kč. Na trhu samozřejmě exituje spousta dalších apliakcí s uzly, ale nás pro svou jednoduchost, přehlednost a názornost nejvíce zaujala právě aplikace Knots 3D. Pokud nejste mistry uzlů, tak aplikaci určitě oceníte a to nejen na moři.

Jedinou nevýhodou by pro někoho mohlo být, že mezi 15 podporovanými jazyky chybí čeština a našinec si tak bude muset vystačit s angličtinou, němčinou či kupříkladu ruštinou. Ale k samotným názorným animacím vázaní uzlů stejně žádný jazyk nepotřebujete 🙂

Google Translate:

The application is available for iOS and Android operating systems and is a little over 20 CZK. In the market, of course, there are many other knot applications, but for us, the simplicity, clarity and presentation of Knots 3D was what most impressed us. If you are not masters of knots you will appreciate the application, and not only at sea.

The only drawback for someone could be that of the 15 supported languages, ​​Czech is missing and you will have to make do with English, German, or Russian, for example. But with the very clear animations tying the knot, you really do not need any language 🙂

The next review is from Androha, a Russian Android review site (Сайт для пользователей Android)


Графическая часть приложения выполнена на высшем уровне. 3D модели веревок тщательно проработаны и неотличимы от настоящих. Физика так же оставляет хорошие впечатления. Полностью отсутствуют малейшие зависания даже на самых слабых устройствах. Приложение быстро и четко распознает манипуляции с узлами, однако для корректной его работы в вашем смартфоне должна быть поддержка мульти-тач (минимум на 2 касания).

Google Translate:

The graphics part of the application is made at the highest level. 3D model ropes are carefully crafted and are indistinguishable from the real thing. The physics also leaves a good impression. The app completely lacks any delay on even the weakest devices. The application quickly and accurately detects manipulation of knots, but for it to work correctly on your smartphone, it should support multi-touch (at least 2 touches).

And in Germany, lists Knots 3D as one of the Top 150 Apps for Android.

Fürs Camping, Segeln, Klettern oder rein zur Dekoration – mit Knots 3D erlernen Sie 87 Knoten und erfahren, wofür sie einsetzbar sind.

And a couple more nice reviews from German sites:


And lastly, we found Knots 3D on a required apps list at John XXIII College in Perth, Australia under the “Outdoor Education” Learning Area.

The College has researched and tested a number of paid Apps during the past 12 months and has finalised a list of applications that will need to be purchased for the start of 2013.

These Apps cover a range of different Learning Areas and may not all be used at the same time in the same way, but will be integrated during the year for various topics and content.

Support: Knots 3D – Bad State

On December 5, 2013, in Frequently Asked Questions, by Administrator

Since the release of iOS 7, we have seen an increase of reports, particularly on older devices (iPad 1 and iPad 2) where Knots 3D (v3.3.x) gets into a bad state.  Reports show this happening occasionally on the Language Selection screen.  We think we have isolated the problem and a fix will be available in the next release due out within the next few weeks.  In the meantime, the following instructions should resolve this and similar issues should they occur:

“Kill” the app and restart it, the problem will go away and most likely you won’t ever see it again.

If you are unsure how to “kill” an app, it is as follows:

– Press the physical home button once to exit Knots 3D
– Press the physical home button twice to see a list (across the bottom of the screen) of apps in memory
– Hold your finger down on the Knots 3D icon until it starts to “jump”
– Press the “-” sign.  This stops the app from running (removes it from memory but does not remove it from your device).  You might want to stop other apps you are no longer using while you are at it.
– Restart Knots 3D in the usual way

– Press the physical home button once to exit Knots 3D
– Press the physical home button twice to see thumbnail views of apps in memory
– “Flick” (swipe up) the Knots 3D view up with your finger to remove it from memory (This stops the app from running e.g. removes it from memory but does not remove it from your device.  You might want to stop other apps you are no longer using at the moment while you are at it.)
– Restart Knots 3D in the usual way

Teknik & Trender – Göteborgs-Posten

On November 11, 2013, in Blog, Knots, Reviews, by Administrator

Utah Fire and Rescue Academy Magazine

On October 24, 2013, in Reviews, by Administrator

Utah Fire and Rescue
Academy Magazine

Knots 3D is featured in this month’s UFRA Straight Tip Magazine (Utah Fire and Rescue Academy Magazine), Oct-Dec 2013 Issue (pdf).

In the Science on Scene section, page 19, it lists a number of apps helpful for Fire Fighter training including Knots 3D.

A few excerpts from the article:

It seems like just about everyone has a smartphone or tablet these days but few of us really explore the full power of these handy devices. Turns out these devices can be used for more than just Facebook and Google. A growing number of apps either have been developed for rescue services or have great useable features for us.

Knots 3D for iOS and Android is a cool, inexpensive app that shows 87 different knots in 3D animation, with more being added. Each knot and its uses are thoroughly described and alternate names shown. Just click on a name on the main list and the knot ties itself and allows you to turn it around to view from different positions. Speed it up or slow it down to stop action to help make learning a new knot a snap.

You really don’t want to be looking at an app right when you need that knot on a scene, but it’s great fun for drills and personal learning.
