our call
Start with PickyStory — highest vibe code, weakest moat.
AppGrowKit
Split the product in half and the answer changes. The screenshot generator is genuinely one-shottable: it is an image model behind a prompt, and a weekend of iteration gets you panels good enough to ship. The tracking half is too, if you only care about apps you own, because Apple's public endpoints hand you ratings, reviews, and chart positions for free. What you cannot build is the part you would be paying for: a catalog of 1.7 million apps across 36 storefronts, with 22 million rating observations and 11 million rank observations accumulated over months. 1.25 million of those apps have more than one day of history and 960,000 have ten days or more, which is the difference between a table of apps and a time series. You can start collecting today, and in six months you will have six months of it. Competitor intelligence, keyword difficulty, and revenue estimates are all reads over that history, so they arrive empty on day one and stay thin for a season. Build it if you track a handful of your own apps. Pay if you need to answer questions about apps you have never opened.
