The Size of Everything

The median app download now sits around 49 MB, and most apps land in the 50-to-200 MB band. A decade ago plenty of useful apps fit in single-digit megabytes; today that featherweight class is the exception. The reasons pile up over time: developers bundle high-resolution images and video, ship multiple UI frameworks, embed analytics and ad SDKs, and pack in on-device assets for features that used to live on a server. None of that is visible to you as a user, but it all still lands on your storage.

The averages here hide a huge split, and one category is responsible for almost all of it. Games average around 220 MB, several times heavier than any other category. Education, social, reference, everything else clusters far below that mark. Games carry that weight because they ship what amounts to a small movie studio's worth of assets: 3D models, textures, audio, cut-scenes, all baked into the download. That's why 0.5% of apps top a full gigabyte, and 68.8% of those are games. If your phone stays perpetually full, you probably don't have a "too many apps" problem. You have a "three big games" problem.

Line this distribution up and it's got a long, dramatic tail. Half of all apps are small, and the 10th percentile sits at a trim 7.6 MB, but the top end runs away fast. The 90th percentile app comes in at 182.3 MB, and by the 99th percentile you're looking at 675 MB, nearly a full gigabyte. That's the real shape of app "bloat." The store isn't uniformly heavy. It's mostly light, with a whale sized tail of giant games pulling the average up.

At the very top, the numbers stop looking like phone apps at all. The largest single download in our data is Assassin's Creed Shadows at 153.37 GB, with Crimson Desert Enhanced close behind at 116.34 GB. The index records file size as published, and at this end of the range that means desktop class software sitting alongside phone apps. These outliers are what make "how big is an app" a trick question: the median lands in the tens of megabytes, while the ceiling sits past a hundred gigabytes.

Here's a cut that runs backward from what you'd expect. You'd guess the app you pay for is the heavier, more elaborate one, but it's actually the reverse: the median paid app is just 19.5 MB, while the median free app is 50.6 MB, more than double the size. Free apps are hauling around the weight of their business model: ad SDKs, analytics, tracking libraries, video assets, and whatever feature bloat it takes to keep a mass audience coming back. A paid app already got its money at the door, so it can stay lean and just do the one job it's there for.

The games split backs this up from a different angle: the median game comes in at 119 MB against 45 MB for everything else. Size has a lot more to do with how an app makes money and what it's built to do than with how "good" or "premium" it happens to be.

Sort apps by the year they first launched and a clear pattern shows up. Apps from 2010 average about 79 MB, while apps from 2024 average 99 MB, which works out to roughly a 25% increase over the period. Faster chips, bigger screens, and cheaper storage arrive every year, and developers put that extra room to use instead of keeping their apps lean. The floor for what counts as a "normal" app size keeps climbing, and it never comes back down.

Size matters, but not in the way most people assume. A large download chews through storage and takes a while to install, and if you're on cellular it can eat real data, so it's worth checking before pulling down a 2 GB game on a metered plan. Size alone doesn't say much about quality, though. A big app isn't automatically more capable, and a small one isn't automatically leaner or more efficient. Different jobs just call for different builds. What's genuinely impressive are the small apps that punch above their weight, tools that stay under 50 MB while millions of people depend on them daily. Doing more with less is the real skill.

The size we record is the App Store's listed download as Apple reports it, and that figure doesn't always match what lands on your device. Apple's app thinning ships only the assets your specific iPhone needs, so your actual install can turn out smaller, while on-demand resources or post-install downloads can push it much larger. Device and iOS version shift the number too. Lean apps still exist if you check the lightest categories: Stickers (median 6 MB), Developer Tools (16 MB), and Utilities (32 MB). We counted every figure here as the listed size across 1,052,228 apps, not an estimate.
