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.
