1,413 development recipes from manufacturer data and the community. Roll tracking from the fridge to the archive. A process timer that knows your chemistry, or lets you run your own.
FilmLokr covers the parts of analog photography that happen after you press the shutter. Recipe lookup, roll management, a process timer that walks you through every step, and fully custom timers for when you want to experiment.
1,413 recipes from manufacturer data and the community, growing all the time. Search by film, developer, or dilution. Adjust for push/pull processing and temperature. Each recipe shows a confidence indicator so you know exactly where the data comes from.
Every roll gets a unique ID the moment you log it. Track from storage, into the camera, through development, and into the archive. Know what's in each camera and what's waiting for chemistry.
Step-by-step development timer. Pre-soak, developer, stop, fix, wash. Agitation alerts at the right intervals. Chemical change pauses between steps. Darkroom mode for processing in the dark. Or skip all that and run a fully custom timer with your own steps and schedule.
Arrhenius-based temperature compensation. Enter the actual temperature of your chemistry and get an adjusted time. No more guesswork, no more paper charts pinned above the sink.
Know which rolls are in which cameras. Assign a camera when you load a roll. See your active cameras at a glance. Useful when you're juggling an M6 with Tri-X and an F3 with HP5.
True black background. Safelight red type. No surface borders, no bright elements. The timer glows. Your night vision stays intact. Designed for actual darkroom use, not just aesthetics.
Manufacturer datasheets as the starting point. Community recipes filling the gaps. Every recipe has a confidence indicator so you know exactly where the data comes from. The database grows over time, and you can always set up a fully custom timer for your own experiments.
Write the ID on the canister. Track what's loaded, what's shot, what's waiting for chemistry. When you've got 50 rolls in the archive and someone asks about that shot from last October, you'll know exactly which roll it was.
Step-by-step development timer with agitation alerts, chemical change pauses, and a darkroom mode that won't ruin your night vision. Use a recipe from the database or set up your own custom timer.
The free tier is genuinely useful. Pro unlocks your complete history for less than the cost of a single roll of colour film.
