Bought the app, this is great. Can I make a feature request? I’d love for it to include a sequence of “levels” or existing equations to try and solve in order of increasing difficulty, and maybe a way to generate a random interesting one. Would love to use this to teach others with a mechanism for regular practice.

I'm adding at least basic support for random practice problems in the release I'll be dropping in a few days. If I can get to it I may also be adding a more gamified "practice" mode.

It doesn't seem like roots can be performed in the web version. Specifically, both x^3=8 and (x^2)x=8 seem unsolvable. It keeps trying to either subtract x^3, or divide by x. I can't get it to create a sqrt no matter what I drag or where. Edit: it seems to create a sqrt only if I drag one of the x-s over to the other side first in order to make one side only x^2, but then I get a sqrt(8/x) which I can't do anything a…

I updated the underlying engine (and its live on the web version here: https://dicroce.github.io/wyrm/home.html). There is some new powers examples in the drop down. Irrational roots are a potential next step.

Try the x^-1 = 2 example and click Guide Me.

The interface is beautiful! Just curious... Did you implement each app natively? I.e. Swift and Kotlin? Or were you able to use a cross platform framework like Flutter?

It uses https://capacitorjs.com/ and I'm super happy with this choice. I think it feels fast simply because solving simple algebra problems is very light work these days (and of course its all on device... so no waiting on the network).

Based. I tend to think of algebra as movement of terms, as opposed to only thinking in terms of operations. This could be really good for building intuition.

Yup. The goal was guide rails.... it'll still let you do non optimal things... just not totally illegal things. Hopefully if you do it enough you can take the guide rails off and still know what to do.
