Lambda Photo is a professional color-grading editor for iPhone and iPad. Open JPEG, HEIC, or RAW, work with a live preview, and export a photo you can be proud of — including HDR HEIC that looks right on an HDR display and still holds up on SDR. Built for light, color, and skin. Exposure, Subject Exposure, and Relight give you control after the shot. HSL, curves, film looks, and .cube LUTs put color back in the image without pushing skin off-natural. Finish with subject, sky, and background masks, linear and radial grades, bokeh, grain, and Golden Hour. WHAT YOU CAN DO • Light: exposure, highlights, shadows, HDR, relight, subject exposure • Color: HSL, curves, temperature, vibrance, split tone, LUT import • Detail: sharpen, denoise, Ultra Denoise, texture, clarity • Finish: subject / sky / background, brush, linear, radial, bokeh, vignette • Looks: profiles, film, presets — plus your own .cube LUT or .dcp • Portrait: skin, eyes, teeth — edge-aware, on device • Batch export and edit from Photos or the share sheet • Formats: JPEG, HEIC, RAW, PNG, JPEG XL Everything runs on your device.

Verdict

The call

The clearest difference is in-app purchases: True Tone Studio at none against Lambda Photo's 1. True Tone Studio also leads on ads (none vs shown) and update cadence (every 4 days vs fortnightly). Lambda Photo's advantage is iOS requirement (18.0 vs 26.5). On price and device support there is nothing between them.
