Exposure IQ: Smart Light Meter

Your DSLR's missing brain. Real-time exposure recommendations built on the APEX equation, for photographers who want to understand their settings, not just guess.

Stop guessing your manual settings. Point your iPhone at the scene and Exposure IQ tells your DSLR or mirrorless exactly what to dial in — ISO, aperture, shutter speed — for any shot.

No subscription. Pay once, use forever.

How it works Choose your shooting goal, point your iPhone at the scene, and get precise settings in seconds. General mode is free. Pro unlocks everything else with a single one-time purchase.

Photography modes (Pro) Portrait · Landscape · Action · Low Light · Macro · Night · Astrophotography · Aperture Priority · Shutter Priority

What makes it different Most light meter apps give you a number and leave you to figure out the rest. Exposure IQ gives you the complete triangle — aperture, shutter, ISO — already solved for your specific goal, your specific lens, and the light in front of you right now.
