Celvion Stack
Photo Stacking
$9.90 · Designed for iPad. Not verified for macOS.
Stack RAW and standard photos on iPhone or iPad—no computer required. Align the Milky Way, reduce noise on device, correct lenses, and export at full resolution.
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.

Celvion Stack 1.3.1 makes settings and exports more consistent.
• Share export settings across the stacking workspace, color editor, and enhancement tools.
• Keep your default format, size, color space, DPI, and processing preference after restarting the app.
• Improve background handling and interrupted-export recovery for color and enhancement tools.
• Improve cancellation handling and preserve recoverable work when saving to Files fails.
• Replay edits from the original image and validate output dimensions instead of relying on a bounded preview.
• Clarify lens-profile support: geometric distortion correction when a matching profile is available.
