What's New in 2.0 It used to stop once it knew how long to leave the shutter open. This time, after the reciprocity math, it stays with you until that frame is done. While the shutter is open, you can see how long it's been and when to close. Tap the Lock Screen and you're back on the frame you're shooting. If it runs past midnight, the date is there too. Pinhole works the same way: put in the meter's aperture, shutter and ISO, and you get how long to leave it open. Not sure which film? Compare a few under the same meter reading. Bracketing? Each frame gets its own reciprocity correction — finish one, then start the next. You can remember the camera and lens; film and metering wait for the day. Before you go out, jot down what you want to shoot tonight. When you're back, you'll see what got finished and what you stopped. Switch phones, and it all comes with you.

Reciprocity data, rebuilt • Dozens of films recalculated from Kodak, Fujifilm, Ilford/Harman, Foma and other maker datasheets • Every film shows its source; you'll be told when a result goes past the published range A clearer result • The result card is now a ledger: metered time, filters, bellows, and reciprocity — each step on its own line Better metering input • Metered time uses a standard shutter dial (including 1/125 and friends), with a keypad for exact values More accurate corrections • Graduated ND (GND) no longer adds to whole-frame exposure — it darkens the sky, not the whole sheet • Calculation order and thresholds aligned with how the datasheets actually read Take your data with you • Export and import exposure history and custom films, so your own curves survive a new phone

NEW: Dark Mode • A warm, darkroom-inspired palette that's easy on the eyes at night • Choose System, Light, or Dark in Settings — takes effect instantly • The Lock Screen timer card adapts automatically Works with MeterGlass • Jump to MeterGlass from the Calculator to meter a scene — your film's ISO comes along automatically • The measured shutter time returns straight to the Calculator, snapped to the nearest stop Standalone Timer • Set a duration right on the Timer tab — no need to go through the Calculator Better Custom Films • Lookup-table films now accept your own data points, so corrections match your film's measured behavior

What's new in 1.4 • Shutter-synced timer — "Set Timer" now arms the exposure; tap the big start button the moment you open the shutter, so the countdown matches your actual exposure. Stop requires a 1-second hold. • Timer survives everything — if iOS kills the app mid-exposure, reopening restores the running countdown. Stale notifications are cleaned up automatically. • Smarter alerts — no more duplicate reminders once you've seen the exposure finish. • Custom filters — add variable NDs or old filters with their measured light loss. • Share preview — see the exposure card before sharing, now with a scan-to-download QR code. • Refreshed result panel — dial-style readout with the corrected time, right beside the start button. • History grouped by date, and the pinhole tool remembers your settings.

What's new in 1.3 • Share cards — turn any exposure into a vintage card and share it (or save to Photos), from the calculator, pinhole tool, and history. • Reciprocity curve — tap the selected film to see its metered-to-corrected exposure curve at a glance. • Timer keeps the screen awake during an exposure, and "Stop" now needs a 1-second hold so a stray tap can't ruin a long shot. • Stronger completion alerts: time-sensitive notification plus follow-up reminders, a completion sound, and a final-3-second countdown buzz. • "One more" button to instantly repeat the same exposure. • Fixed the Live Activity / Dynamic Island lingering at 0:00 after finishing; it now shows a proper "complete" state. • History: edit notes, and pinhole shots are now saved and marked. • Pinhole share cards now include focal length, film format, and aperture. • Updated film data (Harman Phoenix II, Kentmere Pan series) and assorted polish.

v1.2 brings TimerGlass closer to "everything you need at the camera, in one app." • NEW Pinhole tool — design the optimal pinhole for any focal length, verify an existing one, and get Sunny-16 exposure estimates that flow straight into the timer. • NEW Live Activity & Dynamic Island — your countdown stays visible on the lock screen and Dynamic Island during long exposures. • NEW Long-exposure side-effects advice — pull development guidance for B&W, color shift tips for negative & slide film. • Timer is now rock-steady in the background — no more drift after locking the screen. • TimerGlass now remembers your last selected film between launches.

Added Polaroid film stocks (Type 55 P/N, Type 665, Type 669, Type 690)
