    A/B testing is great, but early stages have to trust your gut/experience on it until you can get some more feedback through the testing. For distribution: r/iOSProgramming and r/in…

    Really cool project — the "no backend, no build step" constraint is genuinely hard to pull off well and you did it. Couple things I'm curious about: How does performance hold up wh…

    Really cool project. The self-development pipeline demo is what sold me — that's not just a toy, that's a proof of a real workflow pattern. Few things I'm genuinely curious about: …

    Really like the clarity of the problem here — "I skipped runs because I had nobody to go with" is a sentence that sells itself. One thing I'd watch closely in beta: the cold start …
