A calm home for every collection

Keep the object. Keep the story.

Catalog the things that matter with photos, folders, reusable templates, and fields shaped around your collection—not the other way around.

Built around your collection

Order without losing character.

Flexible records

Give each folder its own reusable template and record only the details that matter.

Photos with context

Keep multiple photos with every item, choose a cover, and rotate images without needless quality loss.

Time Lens

Turn dated photos into a visual timeline and calendar view for collections that grow over time.

Local first, sync optional

Use Crown Jewel entirely on your device. Sign in with NSG ID only when you want server sync across iPhone, iPad, and the web.

Crown Jewel for iPhone and iPad

Your collection deserves more than a spreadsheet.
