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.
