GoKawiilThunderbird Developing Native iOS Email App
The Thunderbird team is building a native iPhone email app from scratch rather than adapting its existing desktop or Android code. Early work focuses on account setup, background sync for reliable connections, and core inbox tools like a formatting toolbar, with the team sharing in-progress screenshots and soliciting user feedback via a research study.
GoKawiil's interpretation of the reporting above, not reported fact.
Building natively rather than porting existing code suggests Thunderbird wants a foundation built for iOS performance norms, which could support faster feature rollout later, according to the team's own framing. An iOS app would round out Thunderbird's presence across desktop, Android and Apple's mobile ecosystem, potentially widening its user base beyond its traditional desktop-focused audience.
- Thunderbird is building its iOS app natively instead of reusing desktop or Android code.
- Early features shown include account setup, background sync, and a formatting toolbar.
- The team is seeking user feedback through a research study before finalizing features.
