Silverlog Timer is a purpose-built timer for darkroom film and print development, with agitation interval tracking and a red-only display mode for use under safelight conditions.

Ratings & Reviews
- This app has not received enough ratings or reviews to display an overview.
Fixed the AGITATE prompt, which stayed on screen after the first agitation. It now clears after three seconds.
Keep Screen Awake now follows its setting and only holds while a timer is running. Choosing a saved process now loads it.
Red Mode now turns every screen red, including the process list, the process editor, the navigation headers and the tip jar, which previously showed white in the darkroom.
Light and Dark now apply as soon as you choose them, and Settings shows the correct app version.
