What's New in ColorDev Timer
1.1
July 22, 2026
ColorDev Timer is coming to your wrist! Version 1.1 is here — the biggest ColorDev Timer update yet. The timer now goes beyond your iPhone, accompanying you throughout the lab with a new Apple Watch app, Live Activities, and more control over every film processing session. APPLE WATCH (new): • Follow the current step and remaining time directly from your wrist. • Pause or resume the timer from your Apple Watch—by tapping the screen or, on compatible models, using the double tap gesture—without reaching for your iPhone.• Receive haptic alerts with 30 seconds remaining, during the final countdown, and at the end of each step. • Manual inversion alerts now reach your Apple Watch too. LIVE ACTIVITIES (new): • Follow your processing session at a glance from the Lock Screen and Dynamic Island. • Check the current step, progress, and remaining time without opening the app. STATISTICS: • You can now manually add previous processing sessions and complete your history for each kit. DEVELOPING AND TIMER: • New option to choose between 3 or 5 minutes of preheating. • Settings have been reorganized to make processing and timer options clearer and easier to access. IMPROVED: • The active step now turns grey when the timer is paused. • App version and build number are now displayed in Settings. • Visual improvements, performance refinements, and bug fixes. See you in the lab!
