Agitate is a darkroom timer for iPhone and Apple Watch. Load a process, fill your tank, press Start, and work by feel: a big countdown and an Invert Now prompt on the phone, a buzz on your wrist at every inversion and step change, and the next event on the lock screen and in the Dynamic Island. You do not have to touch the phone with wet hands to know what comes next. Film-box yellow, black ink, sprocket edges: built to be read from across the room. FREE TO START, ONE PURCHASE FOR THE REST The download is a complete single-tank timer: one tank with up to eight rolls in it, every bundled preset, push and pull by stops, temperature compensation, the Live Activity and alerts, the Sunny 16 meter, and a lab log of every roll you develop. Agitate Pro is a one-time purchase, shared with your family through Family Sharing, that adds up to four tanks at once, the chemistry shelf, the shooting diary and stats, and the Apple Watch app. Sections marked Pro need it. UP TO FOUR TANKS AT ONCE (PRO) Run one tank or four, each with its own process, color and label. Stagger the starts so the tanks come due one after another. Pause one tank while the others keep running, or pause them all. TIMING THAT HOLDS UP Agitate does not count seconds. Every countdown is computed from the moment a tank started and its step schedule, so after time in the background it comes back showing the true state. Inversion, step and completion alerts are local notifications scheduled from those same start times, each with its own sound and haptic setting. APPLE WATCH COMPANION (PRO) The watch takes over a running session: the next tank to flip as a large countdown, other tanks as chips, a swipe to pause or resume. It schedules its own alerts, so it buzzes at every inversion and step boundary with the phone locked in your pocket, and a watch-face complication shows the time to the next flip. PRESETS AND PROCESSES Ships with CineStill Cs41, B&W standard (D-76), E-6 and DF-96 monobath. Build your own with any number of steps, review and adjust each tank before a run without touching the saved process, and share any process as an .agitaterecipe file. CHEMISTRY THAT KNOWS ITS AGE (PRO) Keep a shelf of mixed batches with mix date, rated capacity and shelf life. Attach one to a tank and Agitate counts the rolls through it, warns you at capacity, and extends the developer time for reused chemistry from a published reuse schedule (Unicolor C-41) or a flat per-roll rate. For C-41, a change of developer temperature recomputes the time from the published chart; off the chart, Agitate says so instead of guessing. Optional expiry reminders fire as a batch nears its shelf life. A calculator and the Ilford wash helper round it out. THE LAB LOG AND THE NOTEBOOK Every roll the timer develops gets a journal entry: process, push, temperature, roll number and the real development time, filled in at completion. Name each roll's stock at setup or afterwards, keep a film-stock library with colours, rate the roll and add a note. With Agitate Pro the entry becomes a shooting diary: camera, lens, EI, subject and date shot, with the journal grouped by day or by stock, filtered by date, stock and process, and a stats screen over what you filtered. SUNNY 16 METER A meter you read by eye. Pick the light from six conditions, set the ISO from a film stock or by hand, and read the aperture at 1/ISO. Slide over to see the same exposure at every full stop, and correct a long exposure for reciprocity with published curves. NOTHING COLLECTED Agitate works entirely offline: no account, no analytics, no advertising, no third-party SDK. The only network traffic is Apple's own App Store purchase and restore, handled by iOS. Notifications are local. Your data stays on your iPhone. REQUIREMENTS iPhone with iOS 17 or later; iPhone only. The Apple Watch app needs watchOS 10 or later and installs with the iPhone app. Dynamic Island features need an iPhone that has one.

The call
