About
Film development, your way.
dial is a focused film development timer for iPhone and iPad. Keep your chemistry in view, set up your process and give each bath the time it needs.
STAY WITH THE PROCESS
A large, clear countdown shows your current step and total time remaining. Between baths, dial pauses until you are ready to start the next step.
EVERY STEP. YOUR WAY.
Create custom steps and adjust their durations to match your process. Save your setup as a preset and return to it for your next roll.
KNOW YOUR CHEMISTRY
Keep chemical mix dates and processed-roll counts together. Connect a saved preset to a chemical so your setup is ready when you are.
A GLANCE. BACK TO IT.
Follow the countdown on the Lock Screen and Dynamic Island on supported devices. Allow alarms to receive step alerts while dial is in the background.
MADE FOR YOUR WORKSPACE
Follow your system appearance or choose Light or Dark Mode. Sound and haptic settings let you choose your cues.
No account required. Your inventory, presets and timer settings stay on your device.
Set step times to match your film and chemical instructions.
