Focus on the frame.We handle the chemistry.
A precise, analog-inspired companion for your home lab. Stop guessing dilutions and start developing with total confidence.
The Ritual of the Darkroom
Developing film at home is a labor of love. It's that final, tactile step where your vision finally becomes a reality.
But let's be honest: it's also the most stressful part of the process. Between calculating dilutions, tracking temperature shifts, and staring at a clock, there is zero room for error.
We built DarkroomFlow to take the math out of the equation.
Focus on the art. We'll handle the precision.
Everything you need for a perfect roll
Designed for the reality of a home lab—clean, high-contrast, and out of the way.
Smart Developer Matching
Tell the app what you shot and what chemistry you have on the shelf. It suggests the proper developer, the ideal dilution, and the precise time for the look you want.
Interactive Process Timer
A clear, step-by-step timer that guides you through every stage. From the first pour to the final rinse, you'll always know exactly where you are in the process.
Automatic Temp-Correction
Chemicals rarely stay at a perfect 20°C. Just tell the app your temperature and our algorithm instantly recalculates development time to compensate for the drift.
Digital Lab Journal
Stop relying on scraps of paper or masking tape that get wet and lost. Keep a digital log of every roll so you can replicate your best results months from now.
