Every app in our database carries a dense vector embedding derived from its title, subtitle, full description, and category metadata. To find apps similar to DuckDuckGo, optional Duck.ai, we compute cosine distance against every other app and surface the closest 60 candidates. The similarity score shown on each pick is 1 - distance/2 clamped to [0,1] — 100% means the embedding spaces are identical, 0% means orthogonal.
We then re-rank the candidate set using current App Store rating and review-count signals so a 4.8-star app with 100,000 reviews ranks above a 4.5-star app with 200 reviews even when their embedding distance is similar. Apps that haven't shipped an update in 12 months are filtered out before re-ranking.
The similarity cache is recomputed weekly. Live App Store data (rating, review count) is verified every 6 hours.
