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 clearest difference is ads: Rendix at none against Lambda Photo's shown. Rendix also leads on iOS requirement (15.0 vs 18.0). Lambda Photo's advantage is update cadence (every 2 weeks vs monthly). On price, in-app purchases and device support there is nothing between them.
