## Chronodev Description
Transform your iPhone into an enlarger timer using Chronodev. Chronodev uses HomeKit-enabled wall plugs and lightbulbs to control your enlarger and safelights. Secondhand enlarger timers can be expensive and hard to find. This one costs the price of a wi-fi wall plug.

- Control your enlarger and safelight with your iPhone or iPad
- Expose prints accurately using the HomeKit-enabled timer
- Manual enlarger control for focusing
- Use the metronome for dodging and burning
- Adjust times using EV stops
- Automatically create test strips with incremental exposures, and keep track of exposure times using a handy graph
- Automatically turn your safelight off when exposing/focusing
- Voice control support for hands-free development
- Safe to use in black and white darkrooms when using iOS's built-in red color filter

A HomeKit-enabled wall plug and/or lightbulb is required to use all features of this app. Some features (like a basic timer and EV stop calculations) are available without a HomeKit-enabled device.

## Chronodev Reviews in France

### ***** "Merci beaucoup !"
L’équivalent de fadu timer en encore plus simple avec HomeKit ! C’est parfait ! L’option de calibration ne fonctionne pas sur mon 13 mini mais ce n’est pas très grave. Merci merci merci
-- Sylvainf13, 2025-07-14

### ***** "Super apps"
Hi, it’s a beautiful app very well built! Thank you very much ! Is there any chance you made it evolve to control color bulb too ? To be able to transform any enlarger to a color enlarger ?
