About this app

Guide manual film processing with stage countdowns for develop, stop, fix, and wash. Includes B&W and C-41 reference presets, sound and vibration agitation cues, custom B&W recipes with adjustable development time (Pro), and restoration of an active process after reopening the app.

IMPORTANT: Preset times are general references, not instructions for your film or chemistry. Always follow the film, chemical, and equipment manufacturers’ current directions and safety data. Verify temperature, ventilation, protective equipment, compatibility, and disposal. Never mix unknown chemicals. The app does not monitor temperature or chemical condition.

Purchase restore is included.

Pro: unlimited use, all features unlocked. One-time purchase.
