Proton Mail Enhancements Boost Speed and Design on Mobile

26 Sep 2025

Proton Mail continues to advance its suite of privacy-focused services, unveiling a significant update to its mobile applications for both iOS and Android platforms. This enhancement focuses on delivering a faster, smoother, and more cohesive user experience while also bringing design improvements to the forefront.

Speed and Performance

One of the most notable improvements in this update is the increase in speed, making navigating and managing emails feel more efficient than ever before. Common actions such as opening messages, scrolling through the inbox, or moving emails are now reported to be twice as fast. This speed boost is expected to enhance productivity for users who rely on quick email interactions.

Refined Design

The design refresh introduces a cleaner layout, providing easier access to frequently used actions like composing and archiving emails. The modernized interface not only makes the app aesthetically pleasing but also improves the overall usability of Proton Mail on mobile devices.

Unified Codebase

An important technical milestone achieved in this update is the unification of the codebase between the iOS and Android versions. Now sharing about 80% of their code, the apps are better positioned for synchronized feature releases and fewer bugs. This alignment ensures that updates are reliable across both platforms, enhancing the consistency of the user experience.

Enhanced Offline Capabilities

For users frequently on the move, the new offline mode is a significant addition. This feature allows users to read, write, and organize their emails even in the absence of an internet connection. The changes made offline are automatically synchronized once connectivity is restored, ensuring seamless email management.

While iOS users can already experience the latest version by downloading it from the App Store, Android users are poised to receive the update soon. Proton Mail's commitment to simultaneous feature releases promises that future updates and features will reach both platforms concurrently, eliminating delays and disparities in functionality.
