The Game Center Divide
Achievements and leaderboards were once every game's calling card — who still bothers to wire them up?

Game Center is still around, but at this point it's basically a Games-only tool, and the apps that bother keeping it actually pull in more ratings than the ones that ditch it. Titles with Game Center integration average 11,888.1 ratings versus 9,004.6 for titles without it, and their average star rating comes in at 3.8 versus 2.8. That gap doesn't budge. Developers aren't slapping Game Center onto random apps, they're adding it to the ones built around replaying, competing, and rating, which lines up with what leaderboards and achievements are meant to push people toward.
Adoption has been sliding for a decade either way. Apps released in 2015 integrated Game Center at a rate of 8.8, and by 2025 that number had dropped to 2.9. Outside of Games, developers barely touch it: Entertainment sits at 2.3, and every category below that, Education, Reference, Book, Sports, Health & Fitness, Music, Social Networking, Medical, Productivity, stays under 2.0, with several well below 1.0. Games alone runs at 33.7. Apple built this feature for one category, that category keeps using it on its own terms, and pretty much everyone else has moved on.
More ratings pile up on Game Center titles, and the gap is not small
Apps that integrate Game Center average 11,888.1 ratings. Apps without it average 9,004.6. That gap holds up as a real pattern, not noise. Game Center exists to power leaderboards and achievements, and those features give players a reason to open an app again after the first session. Players who come back get more chances to leave a rating, so the ratings pile grows faster over time. None of this proves Game Center itself is driving the volume. A puzzle game, a runner, or a competitive arcade title, the kind worth building a leaderboard for in the first place, might just be the kind of game people keep coming back to and eventually rate. Either way, if you're scanning App Store signals, Game Center integration works as a rough proxy for repeat engagement, and the rating volume numbers back that up.
Game Center titles carry more content advisories, not fewer
Apps with Game Center average 0.7 content advisories, compared with 0.4 for apps that skip it. That cuts against the assumption that competitive, leaderboard-driven games skew lighter and more family-friendly. The data says otherwise: Game Center apps carry more advisory flags on average. Genre probably explains it. Violence, gambling-adjacent mechanics, and mature themes show up more in action, casino-style, and PvP games, and those are the same games with the strongest reason to bolt on leaderboards and achievements. A word game or a simple puzzle title rarely needs heavy advisory language, and it rarely needs Game Center either. Both traits trace back to genre rather than to each other. Anyone assuming "competitive" equals "safe" should treat this as a flag worth checking.
A handful of publishers built their whole catalog on Game Center, and some of those catalogs look identical
Three names stand out among the 826 titles in the Game Center publisher cut. Ketchapp holds 145 titles, 17.6% of the 826. TPG Tecnologia da Informacao Ltda holds 122, 14.8%. Mobirix holds 89, 10.8%. Together these three publishers cover a large share of every Game Center enabled title. Game Center adoption doesn't spread evenly across indie and mid size studios. It clusters inside the hyper casual, high volume publishing world.
The tail tells a stranger story. Choice of Games LLC, Hiren Patel, Brandon Stecklein, John Smith, and Andrian Andronic each land on exactly 50 titles, 6.1% of the 826. Five separate publisher names hitting the same count doesn't happen through ordinary catalog growth. It reads like templated or shell publishing operations pushing out near identical builds in fixed batch sizes, treating Game Center as a checkbox instead of a design decision. Anyone trying to judge how much developers invest in Game Center should remember that tail. It separates real leaderboard driven design from volume publishing that flips the switch without much thought behind it.
The star rating gap is the single loudest number in this whole study
Game Center apps average 3.8 stars. Apps without it sit at 2.8. A full point on a five-star scale is a big gap, bigger even than the split in ratings volume between the two groups. This is the strongest evidence in the whole dataset that Game Center isn't some legacy checkbox nobody cares about anymore. People genuinely like apps that have it. Building and maintaining leaderboards and achievements takes real, ongoing engineering effort, so the developers willing to put in that work usually care more about quality and polish across the board. Apps that skip Game Center tend to skew toward lower effort, rougher quality, or projects that everyone forgot about years ago, and that 2.8 average is basically the receipt. So if you're using star rating as a quality filter, glance at whether Game Center is integrated too. It's a cheap, easy signal to check.
Release notes barely move the needle, and that's telling on its own
Apps with Game Center average 120.4 characters in their release notes, compared with 112.2 for apps without it. An eight-character gap barely registers next to the star rating gap of a full point, or the ratings volume gap of nearly 3,000 ratings. Developers on both sides write roughly the same amount when describing their updates, yet everything else spreads apart. Game Center adoption lines up with how an app performs and how it's designed, not with how much a developer types into a changelog. Whatever is driving the quality and engagement differences here, it isn't marketing polish or changelog diligence. That's on the app's design and mechanics. So if you were hoping release notes length might hint at developer investment, you'll want a different signal.
Adoption peaked a decade ago and has been falling since
Start with 2015, since that's where the numbers peak: 8.8 percent Game Center adoption, the high point of the whole stretch. After that it drifts downward, though not in a straight line. 7.2 in 2016, 6.1 in 2017, 5.3 in 2018, and then a low of 4.1 in 2019, before recovering some ground to 5.4 in 2020 and 6.5 in 2021. 2022 pulls it back down to 4.6, 2023 rebounds to 5.6, 2024 dips again to 4.7, and 2025 lands at a series low of 2.9. An early 2026 reading then jumps to 5.6. There's no tidy trend line hiding in any of this. It looks less like developers reacting to one Apple policy shift and more like a slow, quiet drift away from the feature altogether. Newer games lean on their own backend services and on third party social or competitive tools instead, and plenty skip persistent leaderboards entirely, particularly outside the core arcade and puzzle genres. That 2026 uptick shouldn't be mistaken for a comeback either. It's drawn from too small a sample of a partial year to mean much. The larger story still holds: Game Center was once a near default inclusion in the mid-2010s, and now it's something only a shrinking share of new games bother to build in at all.
Outside Games, Game Center is basically a rounding error
Games sits at a 33.7 adoption rate. The next closest category, Entertainment, comes in at 2.3. Everything else clusters even lower: Education at 2.0, Graphics & Design at 0.7, Reference and Book both at 0.6, Sports at 0.5, Health & Fitness and Music both at 0.4, Social Networking at 0.3, and Medical and Productivity both at 0.2. This isn't a slope, it's a cliff. Game Center was built around leaderboards and achievements, mechanics that only make sense for competitive or score based experiences, so its near absence outside Games isn't surprising by itself. What the numbers add is a sense of how total that absence is. Even Entertainment, probably the category closest to Games in terms of casual, replayable content, barely touches it. If you want to see how far a cross category engagement tool can travel, this is about as clean a data point as you'll find. Game Center never grew into a general App Store feature. It stayed exactly what it was built to be, a Games feature, and thirteen years on, nothing about that has changed.
The bottom line
Game Center integration has cratered in raw adoption, sliding from 8.8 in the 2015 cohort to just 2.9 by 2025. But where it's still around, it tends to travel with better numbers: 3.8 stars versus 2.8, and 11,888.1 average ratings against 9,004.6. It's also stayed locked into its home turf. Adoption runs at 33.7 in Games versus 2.3 or lower everywhere else, which tells you this was always a Games-first feature. Look at the publishers behind that number, Ketchapp, TPG, Mobirix, and a handful of near-identical 50-title shell-style publishers, and it starts to look like today's adoption is more about high-volume publishing habits than any real investment in leaderboard design. Best to treat Game Center presence as a weak but real quality signal, not something you'd lean on as a general engagement tool.
Method & limitations
How this was made: this study is computed across 266,400 apps carrying the public App Store metadata it needs, drawn from our live index of 923,037 tracked apps, and is recomputed on a schedule. It is a large, representative sample of the store rather than every app in existence, and the figures shift over time as the store changes.
- Public metadata only. These figures come from what apps publicly list in the App Store. Downloads, revenue, retention and in-app subscription pricing are not visible to us — we name them, and we never estimate them.
- A large sample, not a census. The study runs across a representative slice of the store rather than every app in existence, so figures move as the store and our index change.
- Recomputed, not frozen. Numbers are recalculated on a schedule; a figure quoted elsewhere may differ from the one shown here after the next rebuild.
- No estimates or third-party numbers are used.
Common questions
Does having Game Center actually make an app get more ratings?
The data shows a correlation, not proof of causation: Game Center apps average 11,888.1 ratings versus 9,004.6 for non-Game Center apps. The more likely explanation is that both the extra ratings and the Game Center integration stem from the same underlying trait, an app designed for repeat play.
Is Game Center still relevant outside gaming apps?
Barely. Entertainment is the next highest category at an adoption rate of 2.3, and every other category (Education, Graphics & Design, Reference, Book, Sports, Health & Fitness, Music, Social Networking, Medical, Productivity) sits at 2.0 or below. Games alone runs at 33.7, so this remains a Games-category feature almost exclusively.
Are Game Center apps rated higher because they're better made?
The star rating gap is large: 3.8 for Game Center apps versus 2.8 for non-Game Center apps, a full point on a five-star scale. That's consistent with Game Center integration being a marker of developer investment, though the release-notes gap (120.4 versus 112.2) shows that investment isn't about changelog effort specifically.
Is adoption of Game Center growing or shrinking over time?
Shrinking overall. The 2015 cohort had an adoption rate of 8.8, the highest in the series, and by 2025 that fell to 2.9. There's noise year to year (2021 hit 6.5, for instance), but the multi-year direction from 2015 through 2025 is clearly downward.
