Silver Lab vs ClappyBoard

Developing film should feel like a craft, not a calculation. Silver Lab is a darkroom timer built for film photographers who want to focus on the process and not the math. Select your film stock and developer, dial in your temperature and push/pull, and Silver Lab handles the rest. Development times are pulled from an extensive B&W film chart and automatically adjusted for temperature compensation and push/pull processing. For C-41 color negative, the full standardized process is built in and ready to go. When the timer starts, Silver Lab guides you through every stage — agitation cycles, stop bath, fixer, and optional Permawash and Photo-Flo steps. The animated agitation timer tells you exactly when to agitate and when to let the film sit, so you can put the phone down between cycles and not think about it. Features - Automatic development time calculation across a large library of B&W film stocks and developers - Temperature compensation and push/pull adjustment - Configurable agitation timing — set your own initial agitation, rest interval, and cycle duration, independently for Developer and Fixer - Optional Permawash and Photo-Flo steps - C-41 color negative process with push/pull support - Screen stays on throughout development - Live Activity functionality for longer developments - No accounts. No ads. No data collection. Everything runs locally on your device.

ClappyBoard is a digital clapperboard for indie productions. Hold anywhere to arm the board, release to mark. ClappyBoard fires a full-screen white flash carrying the exact time of day, scene and take — a frame an editor can find by eye and a waveform spike they can find by ear. BUILT FOR INDIE BUDGETS No timecode boxes to rent, no jam-syncing between setups, nobody tied up just to hold the clapper. ClappyBoard puts a real sync mark on every take using a phone someone on set already owns — prop it on a stand or hand it to whoever's free. Narrative, doc or commercial, anywhere sound rolls separately from picture. THE WHOLE SLATE IS FREE Every mark, every sound, the full log and CSV export — free, with no limit on takes and nothing held back until wrap. Free boards simply carry ClappyBoard as the production name.
