Spot Light Meter: Film & EV

Spot Light Meter turns your iPhone into an accurate handheld light meter — with the one combination no other light meter app on the App Store offers: a real numeric lux, EV, and foot-candle readout, together with a genuine exposure-triangle solver that calculates ISO, shutter speed, and aperture for you. Point your camera at a scene and Spot Light Meter reads the light reflected back, giving you a precise EV, lux, and foot-candle number instantly — not just a vague "looks about right" exposure guess. Then lock any one of ISO, shutter speed, or aperture, and Spot Light Meter solves the other two — the same exposure math a handheld meter has done for decades, now live on your phone. KEY FEATURES - Live numeric readout — EV, lux, and foot-candle values update in real time as you move the camera - Full exposure-triangle solver — lock ISO, shutter, or aperture and let the app calculate the rest, in Program, Shutter-priority, Aperture-priority, or full Manual mode - Tap to meter any spot in the frame, instead of relying on a single averaged scene reading - Calibration you can trust — dial in an offset from −3 to +3 stops in 0.1-stop increments to match your own camera or process, instead of guessing whether the number is right - Vintage-dial or clean digital display — read your exposure the way you prefer PRO — ONE UNLOCK, NO SUBSCRIPTION A single one-time Spot Light Meter Pro purchase unlocks: - Full Manual, Shutter-priority, and Aperture-priority modes (the free tier includes Program/Auto) - A live histogram, to check exposure balance at a glance - Pinch-to-zoom precision aiming, for tighter framing on distant subjects - Additional focus-reticle shapes — circle, vertical, and horizontal — alongside the free square reticle No scattered tiers, no paywalled core features, no recurring charge. Buy it once, keep it. WHO IT'S FOR Film photographers who want real exposure math, not just a suggestion. Digital shooters who want a second opinion before trusting their camera's built-in meter. Anyone who wants an honest lux or foot-candle number, for any situation where accurate light readings matter. Spot Light Meter is built to be the meter you actually reach for — accurate, fast, and priced once. Download Spot Light Meter and start metering like you mean it.
