Epistles, on your wrist.
Triage the inbox, dictate a reply, accept a meeting. Phone stays in the pocket. Native apps for Apple Watch, Samsung Galaxy Watch, and Google Pixel Watch, with the same feature set on every wrist.
watchOS 10 · Wear OS 3
Built for the small screen, not shrunk down to fit it.
We didn’t port the phone UI and call it a day. The watch app is its own design, focused on the four things you do on a wrist: clear noise, answer fast, see what’s next, and judge whether something is worth pulling the phone out for.
01 · Triage
Clear the inbox without unlocking your phone.
Swipe a row to archive on Apple Watch. Long-press on Wear OS (no swipe primitive there). Each action is optimistic locally and queued back to your phone, which routes it through the same store the desktop and mobile clients use. State stays coherent everywhere.
- Archive, snooze with picker, delete, mark as done
- Pin a message from any view
- Per-account accent stripe so you know which inbox you’re in
02 · Reply
Answer without typing.
Voice dictation, on-device. A row of canned templates you edit from the phone (“On my way,” “Got it, thanks,” “Let me get back to you”). And the one no other watch client ships: Reply & Done. One tap that sends the reply and archives the thread in the same gesture.
- Voice dictation in any system language
- Templates edited on the phone, synced down
- Forward to a recent contact in two taps
03 · Agenda
RSVP without picking up the phone.
Your next event, who’s on it, where it is, whether you’ve responded. Tap Accept, Maybe, or Decline. The reply goes through your account the same way the desktop sends one, full RFC 5546 iTIP, no shortcuts.
- Next event plus the one after it, glance-sized
- Accept / Maybe / Decline on Fastmail, Gmail, and Microsoft
- Honors the default calendar you set for that account
04 · Always present
Complications, tiles, and a banner that does work.
Pin Epistles to your watch face. The complication shows your unread count and the most recent sender; tap to open the inbox. On Wear OS, the same data renders as a tile. Notifications are interactive: archive, snooze, and Reply & Done sit on the banner.
- WidgetKit complications: rectangular, circular, inline, corner
- Wear OS Tiles API for the same data
- Smart Stack placement on Apple Watch
Where every email client sits, on the wrist.
Two device families matter: Apple Watch and Wear OS, and Wear OS in practice means Galaxy Watch and Pixel Watch. Most email clients picked one camp, or skipped the wrist altogether. Here’s the map.
| Client | Apple Watch | Galaxy Watch | Pixel Watch |
|---|---|---|---|
| Epistles | Yes | Yes | Yes |
| Outlook | Yes | Yes | Yes |
| Spark | Yes | No | No |
| Mimestream | No | No | No |
| Mailbird | No | No | No |
| Thunderbird | No | No | No |
| Canary | No | No | No |
| Superhuman | No | No | No |
Outlook is the other client that ships on both ecosystems, and it’s a fine pick if Microsoft is your only inbox. What it can’t do is treat Gmail, Fastmail, and iCloud as first-class peers on the same wrist. Epistles does.
Splits, on the wrist.
The watch app honors the Splits you’ve already set up on the phone and laptop. The defaults are All, Inbox, Reply Later, and VIP; any custom Split you’ve added comes along, in the order you put it in.
On Apple Watch, swipe horizontally or rotate the Digital Crown to move between Splits. On a Galaxy Watch, rotate the bezel. On a Pixel Watch, the side crown. The input is native to each device; the data model underneath is one package.
Get on the list. Get on the wrist.
The watch apps ship with the rest of Epistles. Join the waitlist for an invite when seats open.
