Turn your iPhone into an acoustic timegrapher. Catalog every pocket watch
with the depth a serious collector deserves — by sound, by sight, by data.
Pocket Watch Box is a private collection manager designed for enthusiasts
of mechanical pocket watches, antique stopwatches, and vintage chronographs.
Every detail — from the antique typography to the on-device acoustic
timegrapher — exists because a real collector wanted it.

No accounts. No servers. No tracking. Your collection lives on your device
— and, optionally, in your private iCloud. Audio analyzed by the Acoustic
Timegrapher is processed entirely on-device and is never recorded or
transmitted.
— CRAFTED BY A COLLECTOR —
Built by a pocket watch collector who couldn't find a tool that respected
the craft. Every detail exists because a real collector wanted it.
