Two ways to clank

Tap / NFC-capable iPhones

An NFC tag

Pair a compatible sticker, card or keychain with your iPhone. Use one you own or buy a blank tag.

Scan / iPhone & iPad

A printed QR tag

Generate a code in Clank, print it, then scan the print inside Clank to pair it. iPad uses its camera, so it needs no NFC reader.

Clank is free. Your only tag cost is the NFC tag or printing.

Which tag works with my device?

Keep your tag or printed code away from your device. The walk back is part of the point.

02 / Setup

Pair your NFC tag or printed QR code once. Each scan inside Clank starts or ends a clank with that same tag.

06 / FAQ

Questions
about Clank

Is Clank really free?

Yes. Clank is free to download and use, with all features included and no subscription or premium tier. Use a compatible NFC tag you own or generate and print a QR tag in the app. Any tag or printing costs are separate.

Do I need to buy a special device?

No. Use an inexpensive, compatible NFC sticker, card or keychain from any seller. You can also generate a QR tag in Clank and print it. Neither option requires proprietary hardware.

Which tag works with my device?

On an NFC-capable iPhone, you can pair a compatible NFC tag or use a printed QR tag. iPad uses printed QR tags with its camera. iPhones without NFC can use the QR option too.

For NFC, a blank NTAG213, NTAG215 or NTAG216 sticker is an easy choice. Compatible NFC cards and keychain fobs work too. Choose an on-metal tag if you want to stick it to a metal surface. Prices vary by seller, quantity, tax and shipping.

How does a printed QR tag work?

Generate your QR tag in Clank, print it, then scan the print inside Clank to pair it. To start or end a clank, open Clank and use its scanner on that same printed code. Scanning with the system Camera app does not clank or unclank.

Keep the print away from your device, somewhere you have to get up to reach. A copy of the QR code works as the same tag, so keeping a photo on your device removes that reason to walk back.

Do I need to program an NFC tag?

No. Pair it in Clank and the app remembers its ID. On a compatible iPhone, you can optionally write a link to a writable tag so a tap opens Clank. Printed QR tags are generated in the app and need no NFC setup.

Can I just delete Clank to get around a block?

On iPhone and iPad, strict mode prevents installing or deleting apps while clanked, including Clank itself.

What if I lose my tag or need urgent access?

Clank includes five emergency unclanks for when your NFC tag or printed QR tag is missing, or you need to end a block. They are a limited fallback, so keep your tag somewhere you can return to.

Will it block calls, maps or messages?

You choose what to block. Leave essentials such as Phone, Maps and Messages out of your blocked apps. You can make different modes for work, evenings or sleep.
