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 mask a pretty big split, and one category is doing most of the damage. Games average around 227 MB, several times heavier than any other category. Education, social, and reference apps sit well below that line. Games carry this weight because each one ships basically a small movie studio's worth of assets: 3D models, textures, audio, cutscenes, all baked straight into the download. That's why 0.5% of apps top a full gigabyte, and 69.6% of those are games. So if your phone stays full no matter what you delete, you probably don't have a "too many apps" problem. You have a "three big games" problem.

Look at this distribution and you'll see a long, dramatic tail. Half the apps in the store are small stuff, and the 10th percentile comes in at a trim 8.1 MB. But things get out of hand quickly after that: the 90th percentile app hits 185.8 MB, and by the time you reach the 99th percentile you're at 695 MB, which is basically a full gigabyte. That's the real story behind app "bloat." Most of the store stays light, but a tail of whale-sized games pulls the average way up.

At the very top, the numbers stop looking like phone apps at all. The single largest download in our data is Assassin's Creed Shadows at 153.37 GB, with Cyberpunk 2077: Ultimate trailing not far behind at 139.02 GB. We record file size exactly as published, and at this scale that means the index is scooping up desktop-class software right alongside phone apps. These outliers are why "how big is an app" is kind of a trick question: the median sits in the tens of megabytes, while the ceiling stretches well past a hundred gigabytes.

Here's a cut that runs against intuition. You'd guess the app you pay for is the heavier, more elaborate one, but it's the reverse: the median paid app is just 20.5 MB, while the median free app is 51.2 MB, more than twice as large. Free apps carry the weight of their business model, things like ad SDKs, analytics, tracking libraries, video assets, and the sprawling feature sets needed to hold a mass audience. A paid app already got its money at the door, so it can stay a focused, lean tool that does one job.

The games split shows the same pattern from another angle: the median game runs 122 MB against 45 MB for everything else. Weight tracks how an app makes money and what it's built for, far more than how "good" or "premium" it is.

Line up apps by launch year and the pattern jumps out. Apps that debuted in 2010 weigh in around 80 MB on average. Apps from 2024 average 99 MB, up roughly 24% over that stretch. Faster chips, bigger screens, and cheaper storage arrived year after year, and developers used that extra room rather than leaving it alone. The baseline for a "normal" app size just keeps climbing. It never drops back.

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 whatever download figure the App Store lists straight from Apple, and that number doesn't always match what actually lands on your device. Apple's app thinning only ships the assets your specific iPhone needs, so your real install can end up smaller, while on-demand resources or post-install downloads can push it much larger. Size also shifts depending on your device and which iOS version you're running. A few categories still stay lean: Stickers sit at a median of 6 MB, Developer Tools at 17 MB, and Utilities at 32 MB. Every figure here comes straight from the listed size, counted across 900,038 apps, never estimated.
