Turn a sequence of frames into a cleaner, richer image—entirely on your iPhone or iPad. Celvion Stack gives photographers a complete local workflow for importing RAW/DNG or standard photos, inspecting frames, aligning, stacking, editing, and exporting without a computer. SIX PURPOSE-BUILT STACKING MODES NIGHT Combine multiple exposures to reduce random noise while preserving natural detail and color. MILKY WAY Align the sky and foreground separately so stars can remain sharp while the landscape stays stable. LIGHT TRAILS Blend selected frames into continuous, controlled light trails. SMOOTH WATER & CLOUDS Build a long-exposure look from a sequence, with smoother motion and flexible control. MOVING DISTRACTION REMOVAL Suppress people, vehicles, and other transient elements that appear in only part of the sequence. LANDSCAPE Merge aligned frames for a cleaner, more detailed landscape result. PRO MILKY WAY CONTROL Choose a reference frame, review per-frame quality scores, refine sky/foreground masks, and reject trails from aircraft and satellites, plus other intermittent light streaks, before stacking. RAW LENS CORRECTION When a matching lens profile is available, correct geometric lens distortion. Automatic vignetting and chromatic-aberration correction are not currently included. FULL-RESOLUTION EXPORT Export the final stack as JPEG, PNG, 16-bit TIFF, or 10-bit HEIF, then save it directly to Photos or Files. ON-DEVICE AI On supported devices running iOS 18, use local AI denoise and 4× super resolution. Core stacking works on iOS 17. PRIVATE BY DESIGN Processing stays on your device. Your photos are not uploaded.

Verdict
The clearest difference is price: SCN at Free against Celvion Stack's $9.90. SCN also leads on iOS requirement (11.0 vs 17.0). Celvion Stack's advantage is update cadence (every 2 weeks vs every 68 months). On ads, in-app purchases and device support there is nothing between them.
