How it works

You decide what to lock. Tap your phone on Tranca and keep the tag away from you.

Choose what to lock

In the app, pick the apps that pull you in the most. The essentials — maps, calls, banking, 2FA — always stay open.

Preliminary specifications, to be confirmed in the first production batch.

No catch

Simple outside. Solid where it counts.

Real physical friction

The decision isn’t in your head — it’s in the other room. The distance is what holds the impulse back.

You’re in control

Choose what to block, keep what matters. No turning your phone into a brick.

Works across devices

One tag can serve more than one phone. Or spread tags around the house to lock anywhere.

No battery, ever

The tag is passive NFC. Nothing to charge or replace — it works indefinitely.

A profile for every moment

Focus, family, sleep, study, workout. Build routines and switch between them with one tap.

Made for Europe

Prices in euros, secure European payment (card & SEPA), EU shipping and support in your language.

Frequently asked

How does payment work?

The tag is a one-time purchase. The app has a free version to get you started and an optional Premium — with more profiles and features — for those who want more. Every tag comes with some Premium time included.

Does it work on iPhone and Android?

Yes. On iOS we use the Screen Time API; on Android, the accessibility and administration APIs. The version requirements are made clear in the app before you buy.

What if I need maps or my bank?

They’re never blocked unless you ask. You decide exactly what goes into the lock, and the essentials are always at hand.

Can it be bypassed?

The whole point is to make it a hassle. Without the tag nearby there’s no “ignore limit” button, and strict mode stops you from deleting the app just to escape on impulse.

What if I lose the tag?

You can register more than one and we’ll replace it. Nobody stays locked out forever over a lost tag.

When does Tranca ship?
