Touchstone

A concrete stone with an NFC tag inside, and an alarm that only stops when you tap your phone to it. Keep it across the room. When the alarm rings, you get up, walk over, and tap. That's the whole product.

Hand-cast in Indiana from white UHPC tinted with charcoal, sealed, with a felt pad underneath. About 2.75 inches across and 10 ounces. Every stone comes out a little different.

Works with the free Touchstone app: iPhone 11 or later on iOS 26, or any Android phone with NFC. Handmade in Indiana with an imported NFC tag.

30 nights to try it. Keep it or send it back.
