Knots 3D - Frequently Asked Questions

Pretty Much Everything You Need to Know

  1. Does Knots 3D require an internet connection?

    Knots 3D mobile app is completely self contained and does not require internet access.

  2. What permissions are required to run the Knots 3D app?

    Knots 3D requires absolutely no permissions to run on any of our supported platforms.

  3. What platforms (operating systems) and devices are supported?


    Knots 3D currently works on any Apple device (iPhone, iPad, iPod Touch) that runs iOS 6.0 or later and is available from the iTunes App Store.


    Knots 3D currently works on nearly all Android devices running versions 2.3.3 and up. Knots 3D is available for Android at Google Play and the Amazon Appstore.

  4. When will there be a Windows Phone version of Knots 3D?

    Currently only iOS and Android are supported. We are looking into making Knots 3D available for Windows Phone once we overcome a few technical issues and get the time to do it. Stay Tuned!

  5. When will there be a Desktop version of Knots 3D?

    We are looking into making Knots 3D available for Windows and Mac Desktops. In the meantime, try out our free web version.

  6. What is the difference between the free web version and the paid mobile app versions of Knots 3D?

    The biggest difference is the web version of Knots 3D requires an internet connection while the mobile versions purchased from the app store are completely self contained and no internet is required. Since you often don't have internet access when you are fishing, climbing, camping or other instances you might want to tie or learn a knot, we recommend going with the mobile versions! The web version works well on desktop browsers while the mobile versions are optimized for phones and tablets and have touch interaction with the knot on screen.

  7. Knots 3D is displaying upside down on my device. How do I reset the orientation?

    We have had a handful of reports that occasionally the Knots 3D app displays "upsidedown" after it has been installed. We are unsure why this occurs but typically removing the app from your device and re-downloading and installing it from the app store where it was purchased usually fixes it.

    If reinstalling does not work, we'd be happy to issue a refund.

  8. I deleted Knots 3D from my device. How can I get it back on my phone or tablet without having to pay for it again?

    Once you've purchased the Knots 3D app, you shouldn't ever have to purchase it again. However, you will need to remember what app store you purchased it from and what username and password you used. Once you have succesfully logged in with your username, simply go the Knots 3D app page and re-install it to your phone or tablet. You should not be asked to buy it again if it is the same account (username) that was used for the original purchase.

    App stores where you might have purchased Knots 3D originally include: Apple App Store (iOS), Google Play (Android) or Amazon Appstore (Android)

  9. I just bought a new phone. How can I transfer Knots 3D to a new device?

    The process is the same as if it was accidentally deleted (see above). As long as you use the same account (username) as you used to originally purchase Knots 3D, you should be able to re-download Knots 3D to the new device without charge.

  10. Can I put a copy of Knots 3D on my tablet if I already have it installed on my phone?

    Yes! You can install it on any device where you have an app store account.

    For example, if you have an iPhone, and iPad and an iPod Touch and you use the same Apple ID on all three, you can use Knots 3d and all three devices... At the same time if you want!

  11. My old phone was an Android but my new phone is an iPhone (or vice versa). Is there a way to transfer my purchase between ecosystems?

    Unfortunately, no. Apps are purchased through the respective app stores and there is no way to transfer purchases to another store. HOWEVER, We don't think you should have to purchase Knots 3D twice just because you got a new phone. We have a few options available to us. Contact us for more information.

  12. I purchased Knots 3D from Google Play but it won't install or the app won't launch after install.

    The download and install process is completely controlled by the respective app stores -- in this case Google Play. Typically something is going on with the App Store website that causes problems with the Knots 3D apk download. The majority of these problems are resolved by removing the app from your device and waiting for a few hours and trying again. If this hasn't resolved the problem within 24 hours, please contact Google Play Support for assistance.

  13. I am not happy with my purchase. How can I get a refund?

    We are glad this isn't really a frequently asked question, but if Knots 3D didn't meet your expectations we are happy to issue a full refund. Each app store handles refunds differently. Please follow the appropriate steps below based on where you purchased Knots 3D.

    Google Play

    We have the ability to issues refunds ourselves on Google Play and would be happy to issue a full refund within 7 days of purchase. Please send us the Transaction ID from your purchase of Knots 3D and we will issue a refund back to your Google Play account. The Transaction ID should be on your email receipt or purchase history.


    Apple does not allow developers to issues refunds directly. You have to request a refund directly from Apple Support and have a valid reason for the request. This is primarily meant for cases where you bought Knots 3D by accident or it doesn't work. It's not meant to be a way to get free trials or short term use. An exellent step-by-step explaination of how to get a refund from Apple can be found at iMore: How to get a refund for an App Store purchase.


    As per the Amazon Appstore for Android Terms of Use, all sales are final. If you are unable to complete a download or access Knots 3D, please contact Amazon customer service for assistance or a refund.
