KILLSWITCH

Kill the noise with one tap.

KILLSWITCH is a small NFC block you keep on your desk, in your gym bag, or in another room. Tap your iPhone to it and notifications go silent, distracting apps disappear, and the screen turns gray. Tap again when the work is done.

Buy for $29

Free US shipping. No app to buy, no subscription.

Made in Los Angeles in small batches. Orders ship within 5 business days.

Phone is live. 4 notifications waiting.

What happens when you tap

KILLSWITCH holds a passive NFC chip. Your iPhone reads it and runs the lockdown you set up once. Pick the strength you want; you can use both.

Built into iPhone. No app needed.

Focus lock

An iPhone Shortcuts automation switches on a Focus you design: silent notifications, a home screen with only the apps you choose, and an optional grayscale screen.

Hard lock

Pair KILLSWITCH with a free NFC blocker app such as Foqos. The apps you pick stay locked behind Apple's Screen Time controls until you tap the block again.

It works through distance.

  • Kitchen counterTap in when you sit down to work. Getting your feed back means getting up.
  • Gym bagLock the phone for the session. Your playlist and timer still run.
  • NightstandKill it at 9 p.m. Restore it after your morning routine, not before.
  • Your partner's deskHand them the block. Asking for it back is its own kind of friction.

Straight talk: no blocker is unbreakable. Focus lock can still be switched off from Control Center, and blocker apps keep an emergency override. KILLSWITCH takes away the reflex, the thoughtless reach that turns one check into forty minutes. The discipline part is still yours.

Questions

Does it actually lock my phone?

It locks what you tell it to. In Focus lock, notifications go silent and your home screen shows only the apps you allow. In Hard lock, a free blocker app uses Apple's Screen Time controls to block the apps you pick until you tap again.

Neither mode is a vault. You can switch Focus off from Control Center, and blocker apps keep an emergency unlock. KILLSWITCH works by making the reach deliberate.

Can people still reach me in an emergency?

Yes. Calls still work in both modes, and Focus lets you allow calls and texts from the people you choose, such as favorites or family. Repeated calls from the same number can be set to ring through.

Do I need to download an app?

Not for Focus lock. It uses the Shortcuts and Focus features already on your iPhone. Hard lock uses a free third-party blocker app; the setup guide walks you through one.

Will it work through my phone case?

Most cases are fine. Thick rugged cases, metal cases, and wallet cases holding cards with chips can stop the tap from registering. Hold the top back of your iPhone, near the camera, flat against the block.

How fast does it ship?

We make KILLSWITCH in batches in Los Angeles and ship orders within 5 business days. USPS Ground Advantage usually delivers in 2 to 5 business days after that. You get a tracking number by email. If your order will be late, we email you with a new date and the option to cancel for a full refund.

What if it doesn't help?

Email us within 30 days of delivery and we refund you in full. You don't need to send it back.

Do you ship outside the US?

Not yet. We ship to all 50 states. International shipping comes once production catches up with demand.

Back to KILLSWITCH

Set up your KILLSWITCH

You will do this once. Pick Focus lock if you want zero apps, Hard lock if you want apps fully blocked, or set up both.

The NFC reader on an iPhone sits at the top of the back, near the camera. Hold that spot flat against the block until you feel a buzz.

Focus lock (no app)

  1. Create the Focus. Open Settings, tap Focus, tap +, choose Custom, and name it Killswitch. Under People, allow only who should reach you. Under Apps, allow only what you need, such as Phone, Messages and Maps.
  2. Strip the home screen. In the same Focus, tap the home screen preview under Customize Screens and pick a page with only essential apps. Make that page first if you need to.
  3. Create the tap automation. Open the Shortcuts app, tap Automation, tap +, choose NFC, tap Scan, and hold your iPhone to KILLSWITCH. Name it Killswitch.
  4. Make it instant. Choose Run Immediately, tap Next, then New Blank Automation.
  5. Add the action. Search for Set Focus, add it, and set it to Toggle the Killswitch Focus. Tap Done.
  6. Test it. Tap your phone to the block. Killswitch turns on. Tap again and it turns off.

Optional: gray screen

  1. Pick grayscale. Settings, Accessibility, Display & Text Size, Color Filters. Choose Grayscale, then switch Color Filters back off.
  2. Turn it on with the Focus. In Shortcuts, tap Automation, tap +, choose Focus, pick Killswitch and When Turning On. Choose Run Immediately, add Set Color Filters, and set it to On.
  3. Turn it off with the Focus. Repeat with When Turning Off and set Color Filters to Off.

Hard lock (free blocker app)

  1. Install a blocker app that supports NFC tags. Foqos is free, open source and works with KILLSWITCH. It needs iOS 17 or later.
  2. Make a profile. Choose the apps and websites to block, and allow Screen Time access when asked.
  3. Link the block. Set the profile to start and stop with an NFC tag, then scan KILLSWITCH when prompted.
  4. Turn on strict settings. If the app offers a strict mode that stops you deleting it mid-session, use it.
  5. Test it. Tap to start. Try opening a blocked app. Tap again to stop.

Make it stick

  • Leave the block where restoring your phone takes effort: another room, the car, someone else's desk.
  • Pick fixed times. Kill it when you sit down to work and when you get into bed.
  • Stuck? Email hello@yourdomain.com with your iPhone model and iOS version.

Order confirmed.

Your receipt is on its way to your inbox. We ship within 5 business days and email you a tracking number when your KILLSWITCH leaves Los Angeles.

While you wait, read the setup guide so you are ready to tap on day one.
