- 📦DevGlass version 3.0v3.0: The Development Timer is rebuilt by step. Steps follow the process order. Set duration, temperature, and agitation on each step, and write a bath-change note when you need one. The same bath can be added again. The order can be changed.
Alerts: Background alerts match the on-screen timer. While the timer waits between steps for you to pour off and continue, completion alerts for later steps do not sound early. After a pause, the next agitation alert is recalculated from the time you resume.
Year in review: In Records, you can make the tall image "My darkroom year." It shows sessions by month, days developing, the films and developers you use most, and your density feedback. Saving to Photos requires permission to add photos. That permission is only for this image.
Backup: Sessions, favorites, and chemicals stay. This version can import backups from earlier versions. A backup exported from this version cannot be opened by an earlier version. If you still need a file the old version can read, export it before you update.… more - 🆕DevGlass: its developer released another app: FUFU Journey

About DevGlass
DevGlass is a film development reference and processing timer built for black & white film photographers. Whether you're developing your first roll or you're a seasoned darkroom hand, everything you need is at your fingertips — and it works completely offline.
DEVELOPMENT DATABASE
308 films, 190 developers, and 11,849 development recipes built in. Filter by format (35mm, 120, sheet), pick your film and ISO, and get the exact development time and dilution. Most combinations include push/pull times.
MULTI-STEP PROCESSING TIMER
Start a full process with one tap. The timer guides you through every step — pre-soak, developer, stop bath, fixer, hypo clear, wash, and photo-flo. Each step can be enabled, disabled, or adjusted. Sound and haptic alerts mean you never miss a step, even face-down; progress shows on the Lock Screen and Dynamic Island, and the screen stays awake while timing.
COLOR PROCESSING — C-41 / E-6 (new)
Built-in C-41 and E-6 timer presets with continuous-agitation handling. The Color Process Guide lays out the standard steps, times, and precise temperatures for both processes.
AGITATION REMINDERS
Standard, continuous, minimal, and custom schemes. DevGlass nudges you with sound and vibration whenever it's time to agitate.
COMPENSATION
Temperature compensation (based on the Ilford formula), plus reciprocity and rotary compensation — your adjusted development time, calculated automatically.
DILUTION CALCULATOR
Quickly work out concentrate and water volumes. Common tank presets included (Paterson, Jobo, AP Compact), with custom volumes and any standard dilution ratio.
FAVORITES, LOG & STATS
Save go-to recipes for quick access. Log every session's film, developer, time, temperature, and roll count, with your own notes. Export your log to CSV for backup, and look back on your darkroom year with charts and a year-in-review.
MY CHEMICALS (new)
Track each bottle's open date and shelf life, with a reminder before it expires.
TANK GUIDE
A handy reference for common tanks — capacity, supported formats, and agitation method.
MADE FOR THE DARKROOM
A vintage-print-inspired interface that's easy on the eyes. Available in 6 languages (English, Simplified Chinese, Traditional Chinese, Japanese, German, French). All data stays on your device — no account, no cloud, no tracking.
