Your records, kept together.
Your own process recipes
Enter film, developer, dilution, temperature, exposure index, step duration, agitation intervals and notes. Duplicate a recipe and prepare a named roll or batch.
A timer you control
Start or pause each step and explicitly record it before continuing. The next step stays paused. Planned and actual times remain separate; a completed time does not advance the process automatically.
A process log
Completed runs preserve the recipe snapshot, recorded step times and observations. Export log CSV or a complete .grainbath backup.
Dilution arithmetic
Calculate concentrate and water for a target volume and a 1 + water ratio. Check minimum concentrate, capacity and compatibility yourself.
Know what is included.
No proprietary recipe database or tested processing recommendations. Practice sequences must not be used on real film. Follow film and chemical manufacturers' instructions. This is not a chemistry safety guide, temperature-compensation service, film scanner or hardware controller. Agitation cues are on-screen only; keep a separate timer for critical work.
No app account, ads, tracking, subscription or developer-operated record storage. Cloud-only imports, email and online sharing destinations may need internet.
