Built by filmmakers, for filmmakers — the only iPhone meter that pulls real exposure metadata straight from your camera. No guessing, no pixel-brightness hacks.

ACCURATE COLOR TEMPERATURE Measure CCT in Kelvin from 2000K to 10000K. See green/magenta tint in the units you use — Sekonic CC index, ±, Mired shift, or full CC values. Visual scales show you exactly where you sit between tungsten and daylight.

REAL EXPOSURE, REAL ND RECOMMENDATIONS The ND filter calculator runs the APEX photographic exposure system to ISO 2720 standard. Dial in your cinema camera's T-stop, ISO, FPS, and shutter angle — then get the exact ND density you need. T-stops in half-stop precision (T1.0 to T22). ISOs in third-stop precision (100 to 12800). Frame rates from 23.976 up to 120. Shutter angles from 45° to 360°.

A SPOT METER THAT ACTUALLY HOLDS Drag and resize the spot meter anywhere on frame. HOLD locks the reading like a real Sekonic — not just the position, the value. Take readings on talent, walls, practicals, and compare side by side.

A FULL ON-SET MONITORING SUITE

• RGB Waveform monitor (luminance, RGB, parade)
• Histogram with full RGB channel breakdown
• False color overlay with IRE legend
• LUT preview support
• Illumination meter in lux, foot-candles, EV100 The kind of toolkit that used to live inside a $500 on-camera monitor.

GEL & FILTER RECOMMENDATIONS Tell it your target color temperature. It tells you the exact CTO, CTB, plus-green or minus-green gel to balance the source. Stop fanning through swatch books on set.

CALIBRATE LIKE A PRO Calibrate against known CIE illuminants — D65, D50, tungsten, or your own custom reference. Manual temperature/tint offset and ±3 stops of exposure compensation let you trim the reading to match the meter or camera you trust.

CAPTURE, LOG, EXPORT Save readings with a reference photo, location tag, and notes. Group by date, filter by Today / Tungsten / Daylight / Cool / Logs, or run continuous-sampling Log sessions. Export to PDF or CSV. Save to camera roll. Compare any two readings side by side.

MADE FOR ON-SET Dark UI engineered for set use. Native iPad layout with a dedicated side panel. iPhone and iPad universal.

PERFECT FOR Cinematographers, gaffers, DITs, camera assistants, indie filmmakers, color-conscious photographers, film students, music video and commercial DPs, documentary shooters.
