Email was born on desktop computers. Early email apps for mobile could feel off — the lag when you open a message, the clumsy taps trying to pull up the right draft, the jolt when you switch devices and need to adjust to a different layout.
But today, our phone is our camera, our calendar, our communication hub, our mobile headquarters. We live on our phones. With this in mind, over the past year, we embarked on an ambitious project to rebuild Proton Mail’s iOS(neues Fenster) and Android(neues Fenster) apps from the ground up.
Our completely redesigned apps are fast, modern, and smoother to work with, even when you’re offline. And for the first time, iOS and Android are fully in sync, with the same features and updates arriving side by side.
You no longer have to choose between Big Tech’s convenience or encrypted email’s privacy. Proton Mail lets you have both. Proton Mail v7 (yes, this is now the 7th major release of Proton Mail, but probably the largest update so far) is also a new beginning. Built on an entirely new code base that shares logic across iOS and Android, it will allow us to deliver new features much faster going forward, and they’ll arrive on iOS and Android at the same time.
A modern design that works harder for you
The redesigned interface is clean, intuitive, and built for speed. Navigation is simpler, and the actions you use most (like the composer button), are within easier reach.
This isn’t just about looks. The new design helps you cut through your inbox faster, so you can focus on what matters.
Performance that keeps up
The biggest upgrade in this release is speed. Routine actions, like scrolling your inbox, archiving threads, or replying on the go, all feel instant and are now twice as fast.
Whether you’re rushing to show a boarding pass or catching up on a busy workday, Proton Mail is now built to respond immediately.
Email that works anywhere
Proton Mail’s native mobile apps now have a complete offline mode. You can read, write, and organize your emails without an internet connection. Everything syncs automatically once you’re back online.
That means you stay productive — whether you’re on a train, on a flight, or out of coverage.
The same app on every device
This update finally harmonizes the experience between iOS and Android. Both apps now share the same features — for instance, Android users can now snooze or schedule messages. No matter which device you use, you get a consistent Proton Mail experience.
Overall, we believe the new mobile apps are a major milestone, allowing us to deliver a modern email experience across all platforms while preserving Proton Mail’s best in class privacy and end-to-end encryption.
Built for what’s next
Behind the scenes, we rewrote our mobile tech stack using Rust. Our Android and iOS apps now share roughly 80% of their code, which means faster development and updates that land within the same release window across both platforms. However, our new mobile apps are still native apps, allowing them to have the blistering fast performance that is only possible with native apps. We’ll share a full technical write-up soon.
This rebuild also lays the groundwork for some of the most requested features, and the new architecture will also form the basis of all new Proton Calendar apps which are also on the way, and will also allow for much faster calendar feature releases also.
Getting the update
The new Proton Mail app update is rolling out gradually on iOS and Android, and you might not see it immediately. If you’re on iOS, you can update manually from the App Store(neues Fenster). On Android, the new version will appear automatically as the rollout expands.
As always, let us know your feedback on X(neues Fenster) and Reddit(neues Fenster), and we’ll consider your suggestions.
