For each usage level, it lists the quickest pay-back in each capability class, with each model on its quickest machine and one click into the calculator to change the assumptions. Short version: at 1M tokens/day the best Sonnet-class option is Qwen3.8 27B on a Mac mini M6, 8.3 years. It only drops under a year if you're running agents at around 20M tokens/day.
Fast forward 2 years from this being a side project - it now has over 20k overs and I quit my job a few months ago to work on it full time. Apple featured it as App Of The Day in the UK last year which was a nice point of validation.
Not going to lie, when SwiftUI was brought out I got really excited and jumped into using it right away. Big mistake and headaches, although now it has grown up a lot and there’s a lot fewer bugs and seemingly random behaviour!
Backend wise, I’m using the Firebase platform. Specifically, Auth, Firestore, Functions (written in Javascript), Storage, Crashlytics, Remote Config, Analytics, and A/B testing. For a ‘newbie’ like me it has been a godsend and the pricing so far has worked out really well. Revenue last month was over $2k and Firebase costs were around $3.00
The apps free to use, so feel free to check it out. I’d love to hear your thoughts.
