Apple Watch voice memo, straight to your email.
Some ideas don't survive the time it takes to pull out your iPhone. Capture them on your wrist instead: open the app and send in as few as 2 taps, dictate with watchOS voice input, and launch instantly from the Smart Stack. Every memo lands in your own email inbox — and, if you've set it up, gets auto-appended to your Obsidian vault too.
Simple Memo's Apple Watch app lets you write a memo on the Watch and send it to your own email in 2 taps. Input supports voice dictation, and the app launches from a Smart Stack widget right below the watch face. One thing it cannot do: dictation cannot auto-start the moment the app launches — watchOS public APIs do not allow it (you have to tap the input field first). We explain that constraint candidly on this page.
Why capture on your wrist?
An idea's lifespan is measured in seconds. While you're walking, cooking, on a packed train, or mid-run, the few seconds it takes to pull out your iPhone and unlock it are enough for the thought to dissolve. With an Apple Watch, capture is finished before you'd have reached your pocket.
How it works — as few as 2 taps on your wrist
On the Watch, the interaction is just "open" and "send." For a voice memo, the full flow looks like this.
- Open the app (tap one)
Launch Simple Memo from the Smart Stack widget, a watch-face complication, or the app grid. - Enter your memo
Tap the input field and watchOS offers dictation (mic), Scribble handwriting, and emoji. Finish speaking and your words become text automatically. - Send (tap two)
Tap send and you're done. The memo arrives as an email to yourself — and if Obsidian integration is enabled on your iPhone, it's also auto-appended to your daily note or Inbox note as- HH:mm memo.
Add the widget to the watchOS Smart Stack and the app is one tap away: turn the Digital Crown (or swipe down) from the watch face and tap. Once "raise wrist → turn → tap" becomes muscle memory, an idea reaches your inbox in well under ten seconds.
An honest limitation: dictation cannot auto-start on launch
"Open the Watch app and dictation is already listening" — that was the experience we most wanted to build. The honest conclusion: it cannot be implemented with watchOS public APIs. Here is exactly why, so you know what to expect before downloading.
The technical reason: on watchOS, voice dictation is part of the system text-input UI. A third-party app can do no more than present a text input field — there is no public API to programmatically start dictation. Dictation begins only when the user taps the input field (or its mic) themselves. This is a deliberate watchOS restriction — apps cannot activate the microphone on their own, which protects your privacy — and it applies to every third-party Watch app, not just ours. Any watch app that claims otherwise is describing a different mechanism, not system dictation.
So the realistic fastest flow on the Apple Watch is: raise your wrist → open the app from the Smart Stack or a complication → tap the mic → speak → send. Yes, that's one extra tap for the mic — but in most situations it still beats fishing out your iPhone and unlocking it.
By contrast, the iPhone app supports starting voice input automatically the moment it launches. If a fully hands-on-nothing voice capture is what you want, use the iPhone app's launch-time auto dictation as your primary tool, and keep the Watch app for the moments when even your pocket is out of reach. If a future watchOS release opens up auto-start, we'll evaluate supporting it.
Apple Watch or iPhone — which to use when?
Two-tap sending plus dictation. Best for those few seconds of inspiration while walking, doing chores, or exercising. Launch-time auto dictation is not possible (see the limitation above).
A 0.3-second launch, auto voice input on launch, an offline Outbox queue, and the settings for Obsidian auto-append all live on the iPhone. Longer memos and guaranteed offline capture are the iPhone app's home turf.
Whichever device you send from, memos collect in the same inbox and the same Obsidian notes. Never having to remember where you captured something is the quiet superpower of this setup.
FAQ
Can dictation start automatically when the Watch app launches?
No, it cannot. watchOS public APIs only start dictation when the user taps a text input field — there is no API that lets a third-party app auto-start dictation on launch. This is a watchOS platform restriction that applies to every third-party Watch app, not just ours. Open the app, tap the input field's mic, and speak. The iPhone app, by contrast, does support auto-starting voice input on launch.
Do memos sent from the Apple Watch reach Obsidian too?
Yes. Memos sent from the Watch go through the same sending pipeline as the iPhone app, so if Obsidian integration is enabled on your iPhone, they are appended to your daily note or Inbox note in the same - HH:mm memo format. See the Obsidian integration page for setup.
Does it work offline or without my iPhone nearby?
You can type or dictate the memo on the Watch itself, but sending the email requires a connection — either your paired iPhone nearby, or the Watch's own Wi-Fi or cellular (on cellular models). If you have no connection, send the memo once you're back online.
Is this the official Obsidian app for Apple Watch?
No. Simple Memo - for Obsidian is an independent app developed by YURIKA, K.K. and is not an official Obsidian app. It provides an integration that auto-appends the memos you send to your Obsidian vault. You can also use it purely as a self-email memo app without Obsidian.
Does it support the watchOS Smart Stack?
Yes. You can add the widget to the Smart Stack and launch the app with one tap by turning the Digital Crown (or swiping down) from the watch face — the shortest path from raising your wrist to sending a memo.
How many taps does it take to send from the Watch?
Two taps at minimum: open the app from the Smart Stack or a complication (tap one), then send (tap two). For a voice memo, tap the input field's mic after opening, speak, and hit send.
