A timer for developing film at home. Black and white, C-41 and E-6 in one app, entirely on your device. THE CLOCK IS THE TRUTH Most timers count down, and a counter can stop — when a call comes in, when the system reclaims memory, when the app is force quit. Agitate stores the moment your step ends, not the seconds left in it. A call, a reboot, a phone that ran flat and came back: on return it works out where you are from the clock. There is nothing that can freeze, because there is nothing counting. BUILT FOR A DARK ROOM • Safelight mode: red on true black, screen driven to its lowest brightness, and the Live Activity uses the same palette so nothing lights up behind your back • The whole screen is the button, so you can start the next bath blind, in gloves, with wet hands • Every agitation is a tap in your hand. Sound if you want it, and it plays through the silent switch • Large tabular figures that do not jitter, readable across the room • A segment chain that always shows where you are in the process THE DETAILS OTHER TIMERS GET WRONG • The drain is called ten seconds before time, as the makers specify. A timer that simply rings at nine minutes gives you nine minutes and fifteen seconds of development, every time • Nudge the running step by fifteen seconds, or re-read the thermometer mid-run and let only the remainder be recalculated — without abandoning the run • Agitation as published: four inversions in the first ten seconds of each minute is one maker's scheme, five to seven inversions every thirty seconds is another's. They are not interchangeable. Stand and semi-stand are here too, marked as the community methods they are • Time and temperature converted for black and white between 14 and 27 °C, in Celsius or Fahrenheit. Refused for C-41 and E-6, where deviation is a colour shift that no extra time repairs • Minimum concentrate counted per film, not per tank. A 500 ml tank holds two 35 mm films, so a highly diluted developer can be half short while looking fine EVERY TIME FROM A DATASHEET Hundreds of published combinations, searchable, each row naming the manufacturer document it was transcribed from. No scraped database, no crowd-sourced numbers of unknown origin. If a combination cannot be sourced, it is not in here — write it as a recipe of your own instead, which is unlimited and free. WARNINGS BEFORE YOU POUR Expiry, exhaustion, minimum quantity, re-use surcharge and temperature tolerance are all in the free version. A warning behind a paywall would make the free version dangerous, so none of them are. AGITATE PRO Free develops your film. Pro remembers. • A development journal: every finished run with the film, the recipe, the temperature you actually measured, the push, and your own note. Searchable • A chemistry ledger: bottles with mixing date, fill level and film count, so the app knows when a developer is out of life or out of capacity • Export of all of it, recipes included, as CSV and JSON Pro is a one-time purchase. Not a subscription, nothing renews. PRIVACY No account, no sign-up and no server of our own. The free version loads advertising from Google over the network, and Agitate Pro removes it. Your recipes and your journal never leave your device. Agitate is independent and is not affiliated with, sponsored by or endorsed by any manufacturer of film, paper or chemistry.

It also removes ads. ### Can I customize agitation in Agitate? Yes, Agitate allows for custom agitation schemes, including inversions per minute or per thirty seconds, and supports stand and semi-stand methods as recognized by the community. ### What are the minimum quantity warnings in Agitate? The free version of Agitate includes warnings for minimum concentrate counted per film, expiry, exhaustion, and re-use surcharge, ensuring you have the correct chemical quantities for your development. ### What devices is Agitate available on? Agitate is available on iPhone and iPad devices, indicated by its support for these platforms. ### How often is Agitate updated? The latest version of Agitate is 1.1, which was last updated on September 1, 2026. This indicates a recent update, suggesting ongoing development and support. ## Version history (last 3 releases) ### 1.2 — 2026-09-02 Fahrenheit, and a warmer darkroom. Both of these came from a reader who develops at 78 °F in summer and did not want to ice his chemistry down. • Temperatures read in Fahrenheit or Celsius. The app follows the region your iPhone is set to, so a phone set to the United States now opens in Fahrenheit. There is a switch under More if you want the other one. • Time and temperature conversion now runs to 27 °C (80 °F) rather than stopping at 24 °C. That is where ILFORD's own published compensation chart ends, so the app now covers the whole of it. • The conversion curve is refitted to that chart. The old constant factor ran up to eight percent short at the warm end, and a development time that is too short is a negative that is too thin. ### 1.1 — 2026-09-01 Agitate now shows ads. A banner sits at the bottom of Develop, Times and More, and one full screen ad appears when you acknowledge a finished run. Never during a run, and never on the timer. In safelight mode nothing is drawn at all. Another company's ad is another company's picture, usually a bright one, and white light in a darkroom costs you your dark adaptation and can fog the film. Agitate Pro removes the advertising, and it is still a one time purchase. If you own Pro you see no ads at all, not even in the moment after launch while the purchase is still being read. Where consent for ads is required, the advertising privacy settings are under More and can be changed at any time. ### 1.0 — 2026-08-25 No release notes. ## More apps by Levin David Schwab - [Titi & Bina: Pixel Run](https://appshunter.io/ios/app/titi-and-bina-pixel-run/id6767226388) - [Relatably](https://appshunter.io/ios/app/relatably/id6768082631) - [RateRadar: Fed Rate Tracker](https://appshunter.io/ios/app/rateradar-fed-rate-tracker/id6768628917) - [Noseprint: AI Perfume Finder](https://appshunter.io/ios/app/noseprint-ai-perfume-finder/id6768918518) - [NetGuard: WiFi Scanner](https://appshunter.io/ios/app/netguard-wifi-scanner/id6773480175) - [PulseCheck: Heart Rate Pulse](https://appshunter.io/ios/app/pulsecheck-heart-rate-pulse/id6773665355) All apps by Levin David Schwab: https://appshunter.io/developer/1896432297 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
