RingThing

New in RingThing

Lens data, shared with a tap.

Generate focus, iris, and zoom ring scales from any Lens Data Archive file, share them by QR code, and keep your library organised — all on your iPhone.

Import from anywhere

Bring LDA files in from Files, AirDrop, iCloud, or any cloud provider — the share extension does the rest.

Auto-generate scales

Turn focus, iris, and zoom data straight into ring scales — no more marking rings by hand.

Share via QR

Every lens file becomes a scannable QR — no account needed, no AirDrop dance.

A library you carry

Your LDAs are always accessible — grouped by manufacturer, type, focal length, and serial.

Built for camera teams

Carry your lens data the way you carry your phone

Import Lens Data Archives from anywhere

Pull LDA files in from Files, AirDrop, iCloud Drive, or any cloud provider — the share extension hands them straight to RingThing.

Each archive keeps its focus, iris, and zoom curves intact so the lens behaves on set exactly the way it was calibrated.

Rename the archive, add notes about the lens, body, or session, and it slots into your library ready to share.

Generate focus, iris, and zoom scales — automatically

Pick an LDA from your library and RingThing builds focus, iris, and zoom ring scales straight from the calibration data.

No more eyeballing distances against a printed table or marking rings by hand — the marks land exactly where the lens says they should.

Send the scales to a cutting machine using RingThing's existing export workflow, or share the underlying LDA so a colleague can do the same.

Share by QR — no account needed

Every LDA in your library becomes a scannable QR code. Tap to send, or hold up the screen during prep.

Anyone with the app and a scan has the same lens data you do — no AirDrop dance, no email attachments.

Scanning opens the RingThing app instantly on iPhone. On any other device the link inside the QR lands here, so the recipient can grab the app and import the archive.

A library that keeps itself organised

LDA files are organised automatically by lens manufacturer, type, focal length, and serial.

Mark favourites for the lenses you reach for most, and archive the ones you don't need cluttering the list.

Everything stays on your phone — your library is yours, no sign-in, no cloud sync to manage.
