We make Clank. These are our editorial recommendations based on documented features, with free app blocking and tag choice given the most weight. Read our approach.

Our editorial pick

Clank is the Clank team's number-one editorial pick for free iPhone blocking with an ordinary NFC tag. We like being able to choose a cheap sticker or card instead of buying a specific device. This is a comparison written by Clank's makers, based on documented features. We have not tested the two products against each other.

Clank is available free for iPhone and iPad on the App Store. Tap Out sells a device with a companion app. Its product page describes the package. The main choice is whether you want to choose your own tag or buy a dedicated device.

What the physical tap changes

Tap Out's documented flow is to choose apps and websites, tap the Tap Out Point, then return to it when you want access again. You can put the Point somewhere away from your phone. The company also lists custom modes and schedules. Tap Out explains the process here.

Clank follows that physical pattern with a compatible NFC tag. Your selected apps stay blocked while other apps remain available. You can keep directions or messages accessible and block the feeds you tend to open without thinking. The useful decision is what to block and where to put the tag. An object left beside your phone adds less distance than one you have to walk to.

Our how-it-works section shows Clank's pairing and tapping flow.

Tap Out also avoids a subscription

Tap Out's product page says the companion app is included without a subscription. In the euro storefront checked on September 9, 2026, the selected Tap Out Point was listed at €47.95. Discounts, location and delivery charges can change the amount you pay. Check the current product listing before ordering.

Clank is free to download and use. You supply the NFC tag. As a concrete price example, this NTAG213 sticker was listed at US$0.30 on September 9, 2026, before any applicable shipping and tax. The total tag cost depends on the seller, quantity and delivery.

Tap Out's sharing and social features may suit a couple or friends who want to participate together. We prefer a smaller personal tool for our own phones. Neither preference establishes which product will change someone's habits more.

Check how you get your apps back

A physical blocker still needs a plan for a lost tag. Tap Out describes a Prevent Deletion setting and three urgent access tokens, with replacements requested from the company after those are used. Its FAQ explains Prevent Deletion, and its urgent-access guide gives the reset process.

Clank has strict mode and five emergency unclanks. A normal tag-controlled session ends when you scan the paired tag again; timed sessions and schedules provide other ways to set an ending. These are different choices about access, rather than proof that either product cannot be bypassed. Start with a short session and make sure the apps you need remain accessible before relying on a longer block.

Use a first month to check the setup

It is more useful to give a new blocker a small job than to expect a complete change in your routine. Try one meal on the first day. After a week, look at whether the tag's location is helping or causing unnecessary trips. At a month, review your app choices and any schedules you actually use.

That is a suggested evaluation, not a promised timeline for improved sleep or concentration. We do not have comparative evidence that either app saves a certain number of hours. Notice concrete things instead: whether you return to the same app less often, whether important tasks are blocked by mistake, and whether you continue using the setup.

Choose the setup that fits your routine

Choose Tap Out if you want its dedicated device and included app. We place Clank first for its free app and the freedom to choose an ordinary NFC tag for your iPhone.
