Zenposure: Light Meter

About this app

See the light. Move one dial. Shoot. Zenposure is a calm light meter that lets your film camera and iPhone read light together. Your old camera makes the photograph. Your iPhone reads the light before it. Zenposure stays out of the way and returns a single, large shutter speed you can set directly on the camera in your hand. Beneath that simple surface, on-device AI-AUTO finds a likely person, face, or prominent subject and outlines the area it meters. The recognition and calculation remain quietly in the background. You see only what matters for the next photograph. Open it even when you are not planning to shoot. Point it toward a window, the walk home, or the last light of the day. EV100, the light-position display, current weather, and time to sunset make changing light something you can notice—not just a number you need before a photograph. Set your film ISO, maximum aperture, and fastest shutter speed once. Then point and read. If AI-AUTO chooses differently from you, tap the light you want, or switch to FULL, CENTER, or SPOT. Less interface. Less hesitation. More time with your camera. FEATURES • On-device AI-AUTO finds people, faces, and prominent subjects to meter • FULL, CENTER, and SPOT metering modes • Tap the live view to meter and focus at that point • EV100 and a SHADOW / MIDTONE / HIGHLIGHT light-position display • Direct aperture and exposure-compensation controls • Hold the current reading • Set the fastest shutter speed, widest aperture, and film ISO for your gear • Meter calibration against a reference camera • LIGHT CONTEXT based on Apple Weather and sunrise or sunset timing PRIVACY Camera frames, photos, and Vision analysis results are never saved or sent off your device. Location is used only when requesting current conditions from Apple Weather for the optional light-context label. Zenposure does not store your location. The core light meter continues to work without location access. TRY EVERYTHING FOR 14 DAYS Your first 14 days include every feature: AI-AUTO, SPOT and tap metering, light position, LIGHT CONTEXT, and meter calibration. Afterward, FULL and CENTER metering, EV100, aperture, compensation, HOLD, and camera limits remain available. LIFETIME LICENSE One in-app purchase unlocks every feature for life. No ads, accounts, subscriptions, or automatic charges. PLEASE NOTE Zenposure is a reflected-light exposure aid. It does not support incident-light readings, flash metering, or cinema/video metering. Results can vary with the device, subject, lighting, film, and development process. Calibrate against a reference camera before important shoots.

AI-AUTO now lets you choose the subject directly in the live view. Tap a person, animal, or object to prioritize and track it without leaving AI-AUTO. If the subject is lost, metering safely returns to automatic selection. This update also improves subject acquisition and tracking stability.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
