Amazing but glitchy—no more!

Edit: I can confirm since the update they said it was fixed, I have had no crashes with this app. Knot only was I compelled to write my first app review ever for Knot IQ, but I was compelled to return and update it. Let that be a testament to how useful this app is!

Original review: This will be a five-star app when all the glitches are sorted out, but in its current state it's hardly usable! It frequently freezes up when scrolling through the knot lists, and the only thing to do in that case is shut down the app and relaunch it, losing your scrolling progress. I've also had it freeze during knot display in such a way that prevented me from even turning off my phone screen—in this case, double-tapping the power button to bring up my wallet gave me the escape I needed to shut down the app.

If this were most any other app I had paid money for and I was dealing with crashes like this, I would be giving a one-star review and furiously requesting a refund. It is a testament to how well this app presents its knots—and organizes them so you can find the right knot for the job—that I have still given it a three star review. Hands down the best knot-tying resource I've seen yet, which is why the crashes are so distressing!

After that gets sorted out, I have just one feature request: a button to mirror knots, just in case they're being tied left-handed or the line is going the opposite way around the anchor for whatever reason.

needs flop/mirror on each knot

the reset sometimes flops/mirrors the knot or can switch to left handed mode but that changes for the entire app. knots 3d allows instant mirroring/flopping which can help depending on how the knot you are tying is set up

eta: thank you for your response! yes, your idea to add the local toggle for each knot but keep the global left handed setting is very flexible. looking forward to the update, thank you!
