If you aren’t tracking the global mobile OS market share, you’re flying blind. Developers often waste thousands of hours building features for a demographic that doesn't exist on their chosen platform. Whether you’re optimizing for a high-end flagship or a budget-friendly device in an emerging market, the numbers dictate your technical roadmap. It demands know where the users are, not where you wish they were.
Here's the breakdown of the 2025 field:
The chart above shows a clear, binary reality. Android commands over 70% of the global footprint. This isn't just a number—it’s a mandate that your code must handle thousands of hardware permutations, from fragmented screen densities to varying CPU architectures. If you ignore this, you lose the vast majority of the planet.
IOS sits comfortably at roughly 25-30% of the global slice. While this looks small compared to Android, it represents a disproportionate amount of consumer spending power. In many Western markets, that 30% segment accounts for over 60% of in-app revenue. It’s a classic trade-off: go wide with Android or go deep with iOS.
The "Other" category has essentially flatlined. Once-promising platforms like KaiOS or legacy systems now hold less than 1% of the total distribution. They failed because they couldn't build a sustainable developer ecosystem. It’s a graveyard of good ideas. If you’re still writing code for anything outside of the main two, you’re likely wasting your budget.

When you look at the pie chart, don't just see shapes. See your deployment pipeline. The green slice at 71.0% represents the massive Android install base. This isn't a suggestion; it's a requirement that you build for extreme hardware diversity. It demands test against low-RAM devices and non-standard screen aspect ratios. If your app crashes on a budget handset, you just locked out seven out of ten potential users. That's a massive failure.
The blue slice at 28.0% is the iOS contingent. This number demands that you prioritize high-performance animations and strict adherence to Apple's Human Interface Guidelines. Users here expect a refined, uniform experience. If you try to force a generic, one-size-fits-all UI onto these devices, they’ll uninstall your app within minutes. They have high standards.
That final 1.0% labeled as "Other" is the danger zone. It includes legacy systems or niche OS builds that lack a real app store. Trying to capture this 1% often costs more in engineering time than the total revenue you'll ever pull from it. Ignore it.
Teams often mess up when they try to map these global percentages directly to their own server logs. Don't fall for that trap. Your internal analytics might show a 50/50 split between iOS and Android. That doesn't mean the global market shifted—it means your product has a specific demographic bias. Never confuse your specific user base with the global reality shown in the chart.
In the field, I’ve seen developers struggle when their app performance tanks on the lower-tier Android devices that make up the bulk of that 71%. They optimize for the latest Snapdragon chip and forget about the millions of users on mid-range processors. This is a rookie mistake. You must profile your app on older hardware. If it doesn't run smoothly on a device from three years ago, you aren't ready for the global market.
What if your data sits in the middle? If you're building for a specific region, like Japan or parts of the US, the 28% iOS figure can easily jump to 50% or higher. Always cross-reference this global chart with regional data before you finalize your roadmap. Context is everything.
Your business decisions should mirror the reality of your user's hardware. If your analytics show a heavy bias toward older Android devices, stop pushing high-fidelity 3D assets that chew through battery life. You’re fighting your own user base. Instead, prioritize lightweight builds that preserve system resources. You can download the PDF version of our latest distribution report to keep these figures on your desk for every sprint review.
Android remains stable at the top. While growth in saturated markets like the US has slowed, the platform continues to gain ground in developing regions where affordable hardware is the primary gateway to the internet.
That’s the "iPhone effect." Apple typically releases new hardware in September. We see a predictable surge in traffic from new devices as users upgrade their older models, temporarily shifting the OS distribution percentages.
Historical trends are available via the Statista database. Tracking these shifts over ten years shows how quickly platform dominance can erode if the ecosystem fails to attract developers.
We refresh our data monthly. You should print this chart out and save this guide to compare against next month's shifts. Markets move fast—don't get left behind.
Keep this reference handy. Whether you’re a solo dev or managing a team of fifty, having the raw percentages pinned to your wall prevents bad assumptions. Don't build in the dark.
