He Vibe-Coded a Calorie Tracker to Avoid Paying: 'Most Apps Have No Moat'
weswinder · x · 2026-11-10
weswinder vibe-coded his own calorie tracker app with Opus 5.5 because he didn't want to pay for one — the screenshots show a polished app with calorie budget, macro progress and meal logging. His takeaway: most apps have no moat; if Opus 5.5 can one-shot your app, you might be in trouble. Subscription utility apps like MyFitnessPal face erosion from AI coding.
