## What is Lutter?

Lutter turns iPhone Log footage into a finished look — without learning DaVinci Resolve, and without a yearly subscription.

Built for filmmakers shooting on iPhone 15 / 16 / 17 Pro who want real color grading on the same device they shot on.

ONE PRICE. NO SUBSCRIPTION MAZE.
• Pro — one-time $24.99. All Pro features, forever.
• Pass — $1.99/month, first month free. Optional content drop: one new City LUT pack every month. Independent of Pro.
• Free tier: 6 LUTs, 4 basic sliders, Auto Exposure, full batch processing. No watermark.

Two SKUs. No weekly trap. No four-step upgrade ladder.

BUILT FOR iPHONE LOG SHOOTERS
• Auto-detects Apple Log 1.0 vs Apple Log 2.0 — surfaced as a visible badge, not buried in a dropdown. One-tap manual override for re-encoded clips.
• Skin Tone Fix (Pro) — corrects the magenta-leaning skin tone on iPhone 16 Pro / 17 Pro Apple Log 2 footage. Per-frame Vision face landmarks, per-face override, A/B preview. No competitor ships this in the box.
• Recipe Badge — expand the file's camera metadata with one tap.

GRADE LIKE A COLORIST (Pro)
• 13 hand-crafted LUTs (6 free, 7 Pro), refreshed pack. Import any .cube from Files on every tier.
• Multi-LUT chain — stack primary + secondary with per-slot opacity.
• Cinema Looks — algorithmic CSTs for ARRI Alexa, Sony Venice, RED Helium, Blackmagic Pocket. Stackable on top of any creative LUT.
• Color Wheels — Shadow / Mid / Highlight.
• Tone Curve — 5-point RGB master spline.
• Film Grain.
• Auto-Adjust — Auto Exposure (free); Auto WB, Tint, Highlight Tint, Shadow Tint, tap-to-sample color picker, Live mode (Pro).

PRO SCOPES — INSIDE A LUT APP
No other LUT app on the store ships these:
• False Color overlay with the 9-band ARRI palette.
• Waveform Monitor with IRE guides.
• Vectorscope with 6 target reticles + 123° skin-tone line. Pairs with Skin Tone Fix.

PRO STABILIZATION
Post-process stabilization no other LUT app offers:
• Pairwise homography registration + L1 IRLS trajectory smoothing.
• Three warp modes: Translation / Similarity / Perspective.
• Per-row Rolling Shutter correction.
• Analyze once — Smoothness, Crop, and RS sliders go live in the preview.

FRAME & EXPORT
• Frame tools — crop and reframe, rotate, flip, straighten horizons, and add cinematic bars. Your chosen aspect carries into export.
• Production Settings — pick your codec (HEVC / H.264 / ProRes 422 standard / HQ / LT), resolution (4K / 1080p / 720p), frame rate (24 / 23.976 / 25 / 30 / 50 / 60 / 120 custom), aspect ratio, and bitrate. 10-bit HEVC Main 10 and HDR PQ tagging on Pro.
• Export straight to Photos.
• Adjustments → .cube export (Pro). Bake your grade into a portable 33³ or 65³ cube for Resolve, Premiere, FCP.
• Batch apply — one look across every clip. Per-clip Auto-Adjust optional.

ON EVERY TIER
• Multi-project home grid with real-time autosave. Resume exactly where you left off.
• A/B split preview — long-press, drag to compare graded vs ungraded.
• Live luminance histogram (15 Hz).

PRIVACY
• No ads or cross-app tracking. Anonymous usage analytics and crash diagnostics can be disabled in Settings.
• No accounts or cloud sync. Videos and projects stay on device unless you export them or choose to send diagnostics.
