Exposure IQ Pro offers a monthly subscription for $1.99 with a 3-day free trial, and an annual subscription for $14.99 with a 3-day free trial. ### What photography modes are available in Exposure IQ Pro? Exposure IQ Pro includes specialized modes for Portrait, Landscape, Action, Low Light, Macro, Night, Astrophotography, Aperture Priority, and Shutter Priority. ### How does Exposure IQ's metering differ from other apps? Unlike many apps that provide a single number, Exposure IQ provides the complete exposure triangle (aperture, shutter, ISO) solved for your specific goal, lens, and current lighting conditions. ### What free features does Exposure IQ offer? The free version includes a full light meter with EV display, ISO, aperture, and shutter recommendations, a general photography mode, white balance estimation, and the ability to store one camera body and one lens. ### Is Exposure IQ available on Android devices? Currently, Exposure IQ is only supported on iPhone devices. ### How often is Exposure IQ updated? The app was last updated on June 18, 2026, indicating active development and support. ## Version history (last 5 releases) ### 2.9 — 2026-06-18 A smoother start and a cleaner Pro experience: - Personalized setup. Onboarding now asks for your shooting style, the kinds of photography you do, and your camera gear so the app is tuned to you from the very first shot. - Streamlined mode bar. The photography modes you pick appear first; the rest stay tucked away in Settings, ready whenever you want them. - Easier-to-read Pro screen. Refreshed the upgrade view so everything is crisp and legible. - Simpler pricing. One-time purchase, shown in your local currency. - Various fixes and refinements. ### 2.8 — 2026-05-04 Creative Styles is here. Dial in a custom EV offset (warmer, moodier, high-key) and save it as your own named style alongside the built-in presets. Your style is applied live and baked into every saved photo's settings overlay. Depth-of-field got real. On LiDAR and dual-camera iPhones the DOF overlay now uses hardware depth data for true metric subject distance. Your distance to subject appears live below the focus marker, the near/far bounds are accurate, and the far bound correctly shows ∞ at hyperfocal distance instead of a made-up big number. Saved photos now match your screen. The settings overlay composited onto each shot was rebuilt to mirror the live HUD: goal badge, two-card layout, correct labels and EV, instead of the old mismatched flat card. ### 2.7 — 2026-03-24 Pricing simplified — Pro is now a one-time purchase. No subscription, no renewals. Pay once and every current and future non-SDK feature is yours forever. Performance improvements: faster frame processing, reduced CPU usage, smoother metering response. Creative Styles now available for Pro users — apply Bright, Moody, Vivid, Cinematic, or Soft exposure looks across all shooting modes. ### 2.6 — 2026-02-17 • Added Center Weighted Metering for more accurate exposure when your subject is centered or lighting is challenging • Pro upgrade now includes specialized shooting modes for Portrait, Landscape, Night, and Astrophotography • Added scene analysis with face detection for smarter shooting goal suggestions • New professional tools including live histogram, sun position tracking, and depth of field overlays • Introduced a 3 day free trial for Monthly and Annual Pro plans • Optimized Gear Library for faster lens switching • Improved Smart Lens Clamping accuracy • General performance and stability improvements ### 2.5 — 2026-02-03 Spot metering for more precise exposure in tricky lighting.
