FilmMeter vs Agitate

FilmMeter turns your iPhone into a professional light meter for film cameras. Real-time metering, LiDAR ranging, reciprocity calculation, and exposure logging — one app covers your entire shooting workflow from loading film to the final frame. Metering Measure exposure in real-time using your iPhone camera. Spot metering reads any point precisely, while average metering balances the whole scene. Full control over aperture, shutter speed, and ISO. iPhone 16 users can meter and adjust EV directly with the Camera Control button. Ranging & Depth of Field Get accurate focus distance with LiDAR-enabled devices. The depth of field scale shows your sharp range and hyperfocal distance, supporting 35mm (full frame) and medium format calculations. Camera Management Create profiles for your cameras and lenses. Set focal length and aperture range for each lens, then link a camera when loading film — aperture selection is automatically constrained to your lens's actual range. Manage your digital film bag the way you manage your real gear. Film Roll Management Create a roll, select your film stock, start shooting. Push/pull processing support lets you set development stops and automatically converts to effective ISO. Each metering links to your current roll automatically. The frame counter tracks remaining shots. Mark rolls as in progress, finished, or developed. ND Filters Built-in support for ND2 through ND10000. Select a filter and exposure is compensated automatically — no manual stop conversion needed. Pair with the long exposure timer to master daytime slow shutter work. Reciprocity Compensation Film loses sensitivity during long exposures. FilmMeter includes reciprocity data for popular film stocks and calculates the corrected shutter time automatically. Long Exposure Timer Long-press the metering button to start a countdown. The timer integrates with Dynamic Island — visible even when locked. Get notified when your exposure completes. No more counting seconds for star trails or light painting. Smart Exposure Suggestions Built-in scene recognition analyzes your frame. In tricky lighting like snow, backlight, or night scenes, it tells you "add one stop" instead of leaving you to figure it out. Exposure Log Every metering saves full parameters and location. Export to CSV. Review your decisions, build your film notes. More Features • ND filter auto exposure compensation • Film LUT live preview • Aspect ratio overlays (135/120 formats) • Focal length frame lines (28-200mm) • Darkroom-friendly red-on-black interface • Metric and imperial units Free to Use • No subscription, no account required • Fully offline, no ads • English and Chinese Designed for film photography. Professional enough for experienced shooters, simple enough for beginners.

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.
