How we pick

For this list we ask the App Store the same searches a person would, in several countries, and keep every app it returns. A model reads each app's listing and rejects the ones that only mention the use case. Every app that stays is scored out of 100 from four parts, each 0 to 100 and averaged with no weights: its App Store rating, how many people rated it, where the App Store itself ranks it for this list's searches, and how recently its current version shipped. An app showing Apple's Editors' Choice badge gets a fifth part of 100, which can only lift its score. Tiers follow fixed score bands: S from 90, A from 80, B from 70, C from 60, D from 50, F below. The list's leader is S if it scores 80 or more. On a list of 20 or more ranked apps, a tier from S to D takes in new apps only up to a quarter of the top 40: an app pushed out of a full tier falls to the next tier with room, and F takes the rest. An app already in a tier keeps its place while the tier is at most 2 apps over a quarter; past that, only the apps over that margin go down, lowest score first. Equal scores share a tier, and no app has a better tier than an app ranked above it. An app keeps its tier until its score passes the band edge by more than 1 point, or a full tier or the order above moves it. Only the top 40 of a list get a tier. Read the full method →
