Catalog every crystal, remember where it found you, and uncover its story—quietly, beautifully, yours alone.
Your collection, considered
Photograph a new find and use AI to help identify the stone, then make the record your own.
Your collection, notes, and saved photos live locally on your device—not in a central account.
Turn favorite specimens into considered cards you can send without sharing your private journal.
A note from the developer
I started Crystal Keeper because I wanted a simple, beautiful place for my own collection—not buried in camera rolls or scattered across notes.
I’m a solo developer. Every feature, design choice, and bug fix comes from one person who genuinely cares about getting it right.

Saved collection data stays on your device. A compressed photo is sent for processing only when you actively choose AI identification.
