Lightme vs DevGlass

Lightme - Logbook is a clean and powerful tool to record and keep track of your rolls, shots, developments, and all the gear that revolves around shooting film — from 35mm to medium and large format. The idea behind it is simple: logging a shot should take seconds, not steal time from actually shooting. Lightme pairs a beautiful, immediate interface with enough depth and flexibility to fit any workflow, whether you shoot a couple of rolls a year or fill several large format holders in an afternoon.

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.
