Spirale

The B&W film development app I always wanted — built around how developing actually works, not a spreadsheet of times.

Pair a black & white film and developer, pick a fixer and start developing. Spirale guides your sessions with clear timers, agitation cues, and reusable chemistry tracking. The data you need, organized around how development works — not around the database behind it.

RECIPES. Your darkroom shelf.

Spirale pairs each film and developer in one card, color-coded by packaging, so you spot them at a glance. Films, developers, fixers, all major brands are covered.

• Reusable developers show batch usage and volume right on the card. • Long press on a recipe to rearrange or delete it.

THE EDITOR. All the data, none of the noise.

Fine-tune your development variables: target ISO, developer dilution, temperature compensation and agitation style for your chemistry.

• See the roll count, mixing date and expiry date for reusable chemistry. • Tap the volume to see the dilution. • Pick from official Ilford, Kodak and Agfa agitation styles. • Add or remove optional steps.

THE TIMER. Agitate with precision, leave nothing to chance.

• Arcs around the clockface and dots on the progress bar mark each agitation cycle. • Sound, haptic, and text cues show what to do and when. • Tap the seconds hand or the dial to change the timer’s appearance.

THE PROCESS. Make it yours.

Your own times, recorded as you develop — tracked, averaged, and refined. The longer you use Spirale, the more it reflects how you work.

The datasheet is where you start. Where you end up is yours.
