    Fantastic. My girlfriend is going to love this. ಠ_ಠ


    No internet permissions required and has the Zeppelin bend, so a plus from me.

    Download is a bit large, 50Meg for my phone, but I suppose that's what is needed for 3D views.


      I've been through them all, and it's not the best knot book. It is probably the best FREE knot ebook though.

      My biggest criticism is that they don't show what many of the knots look like after tightening.

      For example, looking at the double-overhand knot, you wouldn't really know what it is for. But if you tighten it (in the upset form which it usually takes), it is a quite pleasing-to-look-at barrel-shaped knot, and is very useful for preventing ropes from fraying at the ends. If you go a bit further and make a triple or even quadruple overhand knot, and tighten it (again in upset form), you get an even nicer effect, and the loose end of the cord can be cut flush with the end of the knot with little fear of the knot working loose.

      Another criticism is what is left out. There are several almost-duplicates of the figure-8 knot, but no mention of the figure-9 loop. The figure-8 knot tends to jam, where the figure-9 loop is more easily undone, and is stronger as well. https://en.wikipedia.org/wiki/Figure-of-nine_loop


    Since it's free, if I download it today and then later on uninstall it, is it still free again should I try to download it again. (As opposed to the 10c etc purchases which are always on my account.)

      You "got" it, therefore it's yours, even though it is not currently on all or any of your Android devices.

      Although you have the right to download it again, I believe you can only download the version that is current at the time of the download. So if the latest version is not as good (maybe the developer inserted ads or broke something), you can't get a copy of the version you originally installed. Also, if an app has been removed from the market, you won't be able to re-download it.

      There is a workaround: there are many apps, e.g. titanium backup, that let you save your installed apps as APK files, which can then be reinstalled. You can store the APK files wherever you like, for example on your SD card or on cloud storage like Google drive. However not all apps can be successfully backed up this way, some apps require additional downloads from the internet, and those may not be available any more. For example, you may not be able to download maps in the correct format for an older version of an offline GPS app.

      Note also that an app installed on Android 4 may not work correctly when installed on a later version of Android. I have found that most work okay, but some don't. One music app had problems scrolling my list of song titles, the scrolling was horribly jittery. I ended up scrubbing and installing the latest version from Google Play, then it worked correctly.

      I use an app called "AppMonster" to backup my apps. I got the early version, before they put ads into it. And since I backed it up with AppMonster, I can now take the old APK file and install the old ad-free version of AppMonster on other devices.


    This app does not show you how to tie the knot the proper way
