Silverlog Timer vs Spirale

Silverlog Timer is a purpose-built timer for darkroom film and print development, with agitation interval tracking and a red-safe display mode that won't fog your paper. HOW IT WORKS Set your development time and agitation interval. Start the timer and get clear visual and audio cues for each agitation cycle. The red mode dims the screen to a safelight-compatible display for print processing. FEATURES • Configurable development time • Agitation interval tracking with alerts • Red safelight display mode for print darkrooms • Audio alerts for agitation and completion • Countdown and count-up modes • Large, readable display • Works offline — no internet connection needed • Dark mode support USEFUL FOR • Black and white film development • C-41 and E-6 processing • Darkroom print development • Any timed chemical process with regular agitation Part of the Silverlog photography toolkit. No account required. No data collected.

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.
