Identify stones with AI, keep a beautiful crystal collection, and return to one meaningful find each day. Start free—no ads, no account required.
Your stones deserve more than a camera roll.
Crystal Keeper is a calm, beautifully designed home for crystals, minerals, gemstones, rocks, fossils, and every meaningful find in your collection.
BUILD YOUR COLLECTION
Photograph a stone or choose an image from your library, then keep its name, category, color, form, origin, treatment, source, memories, and personal impressions together in one place.
GET AI IDENTIFICATION SUGGESTIONS
When you add a stone, Crystal Keeper can provide an AI-assisted identification and optional field suggestions. You stay in control: review every suggestion before adding it to your record.
RETURN TO YOUR STONES
The Today experience brings one piece from your collection back into view, alongside the current moon phase and a private journal for the day.
MAKE IT PERSONAL
Mark stones as Loved or Treasured, save the story behind each piece, explore the colors and themes that shape your collection, and watch your collecting rhythm grow over time.
SHARE BEAUTIFULLY
Create polished share cards from your own photos and collection details, then save or share them using the iOS share sheet.
PRIVATE BY DESIGN
Your collection, journal, profile, and original photos stay on your device. A compressed photo is sent only when AI identification is used. Crystal Keeper has no advertising and does not track you.

Ratings & Reviews
Today’s Crystal now delivers its personalized AI reflection more reliably. We also softened the Go Pro animation on My and polished performance throughout the app.
