iOS, Apple’s flagship mobile operating system, powers iPhones and iPads and is known for its polished interface, strict app ecosystem, privacy features, and tight integration with Apple hardware. However, many users are looking for iOS alternatives due to reasons such as limited customization, hardware restrictions, app store policies, or simply wanting more control over their mobile experience.
Whether you’re looking for more openness, better compatibility with non-Apple services, or a fully de-Googled experience, here are the best iOS alternatives available today—covering mainstream platforms, open-source systems, and privacy-focused mobile OS options.
Android (Stock & OEM Variants)
The most obvious and widely adopted alternative to iOS is Android, which powers over 70% of the world’s smartphones. Unlike iOS, Android is open-source at its core, offering more freedom to customize your device, sideload apps, and choose from a wide range of hardware.
Stock Android (as seen on Google Pixel phones) offers a clean experience with regular updates and native Google services. Meanwhile, manufacturers like Samsung, OnePlus, and Xiaomi offer their own Android variants with additional features, skins, and enhancements.
Best for: Users who want customization, hardware variety, and access to the Google ecosystem.
GrapheneOS
GrapheneOS is a privacy and security-focused Android-based OS designed for Pixel devices. It removes all unnecessary background services and offers hardened security features without including Google apps or services by default.
It’s completely open-source, and while it lacks some mainstream conveniences, it’s one of the most respected choices for users who prioritize digital privacy.
Best for: Privacy-conscious users and developers who want a hardened Android alternative with no data tracking.
LineageOS
LineageOS is an open-source operating system built on Android, and it’s a direct successor to the popular CyanogenMod project. It allows users to install a clean, customizable OS on a wide variety of devices without bloatware or pre-installed apps.
With support for root access, OTA updates, and a large community, LineageOS appeals to power users who want full control over their device.
Best for: Android enthusiasts and users who want to breathe new life into older phones with a secure, customizable OS.
/e/OS
/e/OS (formerly known as Eelo) is a de-Googled version of Android focused on user privacy. It includes its own app store, cloud services, and tracker-free apps—all while being familiar enough for everyday smartphone use.
While it’s based on Android, /e/OS replaces core Google apps with open-source alternatives and doesn’t rely on Google for cloud services or data syncing.
Best for: Users seeking a Google-free mobile experience with practical alternatives for email, maps, contacts, and calendar.
CalyxOS
CalyxOS is another privacy-focused Android fork, offering pre-installed tools like Signal, Tor Browser, and F-Droid. It allows limited access to Google services through a sandboxed method (MicroG), giving users balance between privacy and usability.
It’s maintained by a nonprofit foundation and is compatible with select Pixel and Android devices.
Best for: Users who want better security and privacy but still need limited access to Google services.
Ubuntu Touch
Ubuntu Touch, developed by the UBports community, is a mobile operating system based on Linux. Unlike Android or iOS, it’s built from the ground up for convergence between mobile and desktop. It supports gestures, web apps, and native apps written in Qt.
While app support is more limited, it has an active open-source community and works on devices like the PinePhone and select Nexus models.
Best for: Linux users and developers interested in convergence and full control over mobile computing.
KaiOS
KaiOS is a lightweight mobile operating system based on the now-defunct Firefox OS. It brings smartphone-like features to feature phones, including 4G, WhatsApp, Google Assistant, and Facebook support—even on devices with physical keypads.
KaiOS is not an iOS replacement for power users but provides basic functionality for those who want affordable, non-touchscreen phones with essential apps.
Best for: Budget users or those wanting simple, minimal mobile devices with smart capabilities.
HarmonyOS (by Huawei)
HarmonyOS is Huawei’s in-house operating system built as an Android alternative following U.S. sanctions. It is designed for a broad ecosystem including smartphones, tablets, TVs, and IoT devices.
While it shares some architecture with Android, HarmonyOS is evolving into a separate system, especially in China where Huawei leads the mobile market.
Best for: Users in regions where Huawei devices dominate and where access to Google services is limited or restricted.
PostmarketOS
PostmarketOS is an experimental Linux-based OS designed to run on smartphones with a goal of long-term device sustainability. It’s not suitable for average consumers yet, but it offers full Linux environments on mobile hardware.
This OS focuses on privacy, open-source values, and extending device lifespan. It runs on very limited phones today but has strong community interest.
Best for: Developers, tinkerers, and open-source purists looking for full Linux on a phone.
Tizen OS
Developed by Samsung, Tizen OS is used mostly in smart TVs and wearables but has also appeared on smartphones. While no longer Samsung’s focus for phones, it represents one of the few non-Android mobile OS platforms from a major manufacturer.
Though limited in app support, it’s relevant in the context of alternative operating systems for wearables and other smart devices.
Best for: Developers targeting IoT and wearable ecosystems with non-Android software.
Choosing the Right iOS Alternative
If you’re moving away from iOS for more customization and flexibility, stock Android or OnePlus/Samsung devices offer the most seamless transition. For users focused on privacy and open-source values, options like GrapheneOS, /e/OS, and CalyxOS provide meaningful alternatives with greater control over data.
Power users and developers may find freedom in Ubuntu Touch, LineageOS, or PostmarketOS, while those wanting a lightweight, minimalist experience might explore KaiOS. With mobile privacy, control, and diversity becoming more important in 2025, the alternatives to iOS are growing—and becoming more capable than ever.
