No sous-vide. No guesswork. Just consistent colour film development. ProLab is a precision colour film development tool with real-time time compensation and chemistry tracking. ProLab Film Developer is the smarter way to develop colour film at home. Most home colour film development goes wrong for two reasons: temperature drift and tired chemicals. Every other app ignores that. ProLab Film Developer doesn’t. It’s the only app that actively adjusts your development time in real time, based on what’s actually happening, not what should be happening. Real-time time and temperature correction Built around a Dynamic Time-Temperature Engine, ProLab continuously recalculates your development time as conditions change. Temperature drops? Time is adjusted. Chemistry weakening? Compensated. No guessing. No assumptions. No expensive setup. No barriers. You don’t need a sous-vide. You don’t need a lab. Just a tank, a thermometer and a bowl. This is consistent, repeatable colour development without the cost or complexity. What makes it different • Real-time time compensation based on live temperature input • Chemistry tracking with exhaustion awareness • Intelligent adjustments based on actual usage, not theory • Built-in push processing for 1 and 2 stops • Clean, guided workflow from start to finish Supports major home C-41 kits, including Cinestill, Bellini, Rollei, Adox, Fuji and more. Built by a photographer, not a developer This was made to solve a real problem in home film processing. If your temperature moves and your timing doesn’t, you’re already off. Get it right. Every time. ## Key features - Real-time time compensation - Chemistry tracking - Dynamic Time-Temperature Engine - Push processing support - Guided workflow - Supports major C-41 kits ## Chart rankings - #195 in Top Paid · Photo & Video (US App Store) ## Recent user reviews (9 of 9) All indexed reviews: https://appshunter.io/ios/app/prolab-film-developer/id6759682425/reviews.md ### 5/5 — great app *2026-07-03* love it but is there a way to have an alarm go off or something when the timers are done? ### 5/5 — Best Color dev app! *2026-05-01* Never write reviews, developed my first color roll and used this app. So happy with the results, the negatives came out perfect. Im sure there are other apps out there that sort temp etc but ive not tried them, but this one works perfect so it’ll do! ### 5/5 — Great stuff! *2026-04-11* Did a roll with this the other night. Nothing fancy setup wise. Negs came out really clean so yeah, happy with it. ### 5/5 — Digital timer for an analog process *2026-04-10* Easy to use, looks great and love the warnings it gives based on chemistry exhaustion + history. ### 5/5 — Promising! *2026-04-09* Can’t wait to try this. Is it possible to add different film sizes? 4x5? 120? Thanks! ### 5/5 — Perfect Results! *2026-04-09* Developed two rolls of film through the app. Results were bang on with both, the negatives were perfect! ### 5/5 — Great *2026-04-07* Pretty handy tbh. I usually just run a timer and hope for the best but this feels a lot more dialled in. ### 5/5 — Easy to use *2026-04-07* Like that it tracks the chems. I never remember how many rolls I’ve put through them. Makes it way easier. My temp didn’t drop during this roll tbf, but cool feature if it works. ### 5/5 — Impressed so far… *2026-04-06* Just downloaded this, so only run one roll through so far, but it works! Temp time adjust was ace, made a small time change mid dev and it worked! I like it. ## Frequently asked questions about ProLab Film Developer ### What is ProLab Film Developer?
