How to set up Back Tap on iPhone to capture notes

A 2-minute setup that turns the back of your iPhone into an instant capture button. Triple-tap, speak, and the thought is saved before it's gone.

Back Tap is a built-in iOS accessibility feature: tap the back of your iPhone and it runs an action you choose. Point it at MindBlink and a thought goes from idea to saved and understood in under a second — no unlocking, no hunting for an app, no blank note staring back at you. Here's the exact setup, plus what to do if a tap doesn't register.

MindBlink turns that Back Tap into an instant voice note — recording in under 800ms, fully on-device. Get MindBlink on the App Store

Set it up in three steps

1

Open Back Tap settings

On your iPhone, go to Settings → Accessibility → Touch → Back Tap. (Search "Back Tap" in Settings if you can't find it.)

Settings · Accessibility · Touch
2

Assign Triple Tap

Tap Triple Tap, scroll to the bottom under Shortcuts, and choose MindBlink's Capture Thought action. Open MindBlink once first so the action is registered.

Triple Tap → Capture Thought
3

Triple-tap and speak

Tap the back of your iPhone three times. MindBlink launches straight into recording — even from a cold start, even from your pocket — typically in under 800ms. Speak, and it's saved.

Back tap → live mic, under 800ms

That's it. There's nothing else to configure — MindBlink transcribes, reads what you said, and schedules it to resurface when it matters, all on your device.

Don't have the app yet? Step 2 needs MindBlink installed and opened once so Capture Thought appears in the list. Download MindBlink on the App Store

Prefer not to use Back Tap?

Back Tap is the fastest trigger, but it isn't the only one. The same one-tap capture lives in several places — use whichever your hands reach first.

Control Center Action Button Lock Screen Home-screen widget

If a tap doesn't register

Triple-tap isn't launching MindBlink
Re-open Settings → Accessibility → Touch → Back Tap → Triple Tap and confirm MindBlink's Capture Thought is selected. The action only appears after you've opened the app at least once. Back Tap can be less responsive through thick or metal cases — tap a little more firmly near the Apple logo, or use Control Center, the Action Button, or the widget instead.
I don't see a MindBlink option in the list
Scroll to the very bottom of the Triple Tap screen — app actions live under the Shortcuts heading, below the system options. If it still isn't there, open MindBlink once, then return to Settings so iOS can register the shortcut.
It fires by accident in my pocket
That's exactly why MindBlink uses Triple Tap rather than Double Tap — three deliberate taps rarely happen on their own. If you still get the occasional stray capture, just shake to erase it; nothing is kept that you didn't mean to keep. You can also move capture to the Action Button if you'd rather not use Back Tap at all.
Recording starts but nothing is transcribed
MindBlink needs Microphone and Speech Recognition permission (Settings → MindBlink). Grant both, then triple-tap again. Everything runs on-device, so transcription works even with no signal.
Does Back Tap work when the phone is locked?
Yes. A triple-tap launches MindBlink straight into recording from a locked, cold-start state — typically in under 800 milliseconds — so you can capture without unlocking first.

Never lose a thought again

Set up Back Tap once and the next great idea is already taken care of. Triple-tap. Speak. Done.
