The App Store, by Category

The store is wildly lopsided. Games leads the pack with over 124,159 apps, dwarfing the quiet niches sitting at the bottom of the list. Crowding cuts both ways here. As a user you get almost infinite choice, but you also get brutal noise, and the app you actually want ends up buried under a hundred lookalikes. For a developer, the popular categories are exactly where it gets hardest to stand out. Plenty of smart teams skip that fight entirely and go after smaller, less contested categories instead, where a good product actually has a shot at surfacing.

If you rank categories by average rating among apps with a real volume of reviews, the tiers shake out pretty cleanly, with Food & Drink and Health & Fitness sitting at the top. A high category average tends to mean one of two things is going on. Either the apps are just well built (games are a good example, since execution matters a lot there and users are quick to rate them harshly), or the category draws a smaller, more committed audience that's only downloading something it already went looking for. Bottom line: some categories are just safer bets to download from at random than others.

You can tell a lot about a category just by looking at whether people are paying for it. Shopping (99.1% free), Magazines & Newspapers (98.9% free), and News (98.5% free) all lean on ads and traffic to make money, so almost nothing there sits behind a paywall. Stickers (67% paid), Developer Tools (23% paid), and Music (17% paid) tell a different story: users show up looking for one specific thing, and they're generally fine paying for a tool that actually delivers. So when an app breaks that pattern, a paid app tucked into a mostly free category, or a free app hanging around a bunch of paid ones, it's worth a second look. Usually the developer made a conscious choice about how that particular app should earn its keep.

App counts tell you where developers pile in; they do not tell you where the attention is. Add up every star rating ever left, all 2.94 billion of them across the categories we track, and the picture sharpens. Games alone pulls 24.2% of all ratings in the store (710,060,785 of them), roughly one rating in five, which makes it the most-used aisle as well as the most-crowded one.

But look past the top line and the crowd-versus-attention gap opens up. Shopping is a mid-sized category by app count, yet its apps average 21,750 ratings each, the densest audience per app in the store, because a handful of essentials (a bank, a retailer, a delivery app) each own tens of millions of users. A category can be quiet on the shelf and enormous in the pocket. Where you find few apps but huge rating counts, you have found a winner-take-most market, not a sleepy one.

Ratings don't spread evenly within a category. Almost every aisle has one app sitting far above everyone else, and that top app matters because it sets the ceiling everyone else gets measured against. YouTube leads Photo & Video with 48,834,986 ratings, while Facebook tops Social Networking with 28,179,542. These apps basically define what "normal" looks like in their category, which is why a newcomer sitting on a few thousand ratings can still feel invisible next to them.

The giant is a mixed bag for you: a safe, well-tested default, but also the app everyone already has installed. So look just below it. That's usually where the more interesting finds sit.

Age varies a lot by category, more than you'd guess. If you look at the median launch year of the apps in each one, News comes out as the oldest, with a typical app dating back to 2019. Developer Tools sits at the other end, with a median app from 2025. Think of it as the gap between a neighbourhood that's been there for decades and one that just broke ground. That lines up with what's happened in tech generally: categories that catch a fresh wave fill up fast (design and developer tooling have grown a lot this decade), while older aisles got built out long ago and have mostly just been maintained since.

Age alone won't tell you if something's worth using. A young category mixes the newest ideas in with apps nobody's really tested yet. An old one has proven survivors sitting next to things nobody's opened in years. Check the category's age against an app's own launch date and last update, and you'll have a much better sense of what you're actually looking at.

Two honest limits worth flagging here. First, every app in this dataset falls under a single primary category, whichever one its developer picked, so something like a photo-editing note-taking app or a fitness game ends up on one shelf when it could just as easily sit on two. The category lines look cleaner in the data than they actually are. Second, rating counts are lifetime US totals, and they stand in for attention, not downloads or revenue. Apple doesn't publish those numbers, so we're not going to guess at them. A category average also flattens a lot of internal spread: Games holds both the best and the worst apps in the store. Treat these figures as a map of the shelves, not a ranking of what sits on them.
