Photo Timers vs DevClock

This app consists of three timers for analog photographers: Long Exposure Timer provides both a visible and audible pulse, allowing you to time long exposures without needing to look at your phone. You can place the phone in your pocket, wear a Bluetooth earbud, and let the pulse help you count seconds. Parallel Development Timer allows you to time each development tank independently, based on the specific process required. Dark Room Timer features a dim display suitable for darkroom use. The timer can be reset by slightly raising the phone by a few millimeters from a corner, even while wearing latex or safety gloves. You can return to the main view by swiping left or right on any of the individual timers or on this help page.
