The app itself is fairly straightforward, but it included some intermediate complexity in terms of audio capture and calling local models. Both something I'd never done, and as not-a-mac dev something I probably wouldn't have attempted for a side-project while I'm meant to be bootstrapping my own thing.
I didn't touch a line of code, and I was blown away. I'm so impressed in fact that I'm predicting we'll see a resurgence in native apps in the near future. By far the worst (and slowest) part of the process is having to deal with the App Store, and the ridiculous hoops you have to jump through to get past review.
