FilmDeveloperPro is a precise darkroom tool built on authentic development times sourced directly from manufacturers.
Use the smart development time calculator to estimate missing times based on push/pull, dilution, temperature, and agitation.
The built-in timer with agitation reminders keeps every step on track — from presoak and development through stop bath and fixer.
Key features:
• Accurate calculator for missing development times
• Manufacturer-sourced reference data
• Cine film format support: Kodak Double-X, Foma Fomapan Cine, ORWO, and more
• Custom development time entries
• Fully adjustable push/pull, dilution, temperature, and agitation
• Multi-step timer: presoak, developer, stop bath, and fixer
• C-41 workflow for chromogenic black & white films like Ilford XP2 and Kodak BW400CN
• Live Activity shows your timer on the lock screen
Whether you develop black & white or chromogenic C-41 films, FilmDeveloperPro makes every step controlled, reliable, and repeatable.
Have to restart the app every time I change film type or it fails to find developer solution/ gives wildly incorrect info.
• New C-41 workflow for chromogenic black & white films like Ilford XP2 and Kodak BW400CN — compatible with chemistry kits from CineStill, ADOX, Tetenal, and more.
• Bug fixes and stability improvements for a smoother experience.
