Zeus Focus Stacking vs Eagle Image Stacker

Every Pixel. Razor Sharp. Zeus Focus Stacking turns your iPhone into a professional macro lab. Capture multiple frames at different focus distances, blend them into one perfectly sharp image — front to back. PRECISION CAPTURE • Focus Range — set Near and Far brackets on the live preview, so each stack sweeps only the depth you want • Tap to rack focus straight to any subject plane • Automatic focus bracketing — sweep from near to far in seconds • 10 or 20 frames per stack • Linear or macro-biased focus distribution for optimal coverage • Capture Speed — Max Speed, Balanced, or Max Quality for the focus bracket (Pro) • Ultra 48 MP — capture the whole bracket at the sensor's full resolution, on iPhones with a 48 MP-class sensor (Pro) • Lossless 12 MP zoom via the wide camera • Shoot in portrait or landscape — your photo always comes out the right way up INTELLIGENT ENGINE Advanced focus-stacking built for iPhone. Smart alignment holds your frames in register through hand-held movement, lens breathing and focus shifts, and the 2.0 engine renders them into a single image with finer detail and cleaner edges than any Zeus release before it — clean outlines where your subject meets the background, no glow around bright points, and no doubling when something shifts between shots. Core stacking runs on-device; optional iCloud sync and showcase uploads stay under your control. PRO AI POST-PROCESS • Capture Speed — pick Max Speed for near-instant brackets (lighter per-frame processing) or Max Quality for the most per-frame detail; every stack exports at full resolution • Details Enhance — neural micro-contrast and edge recovery at native resolution • 2× Super Resolution — print-grade upscaling for galleries and large prints • iCloud Sync — projects and original frames across all your devices GALLERY THAT KEEPS UP • Original frames preserved for every project — re-stack with newer engines anytime • Smart regenerate — change Super Resolution mode without redoing the whole stack • HEIC and JPEG export, native Photos sharing • Picture of the Week — submit your best focus stacks to the gallery TUNED TO EACH iPHONE Each iPhone model gets its own calibration profile, so the stacking engine knows exactly how your lens behaves. Sharper alignment, no manual tweaks. SMART ON ANY DEVICE Intelligent memory management lets large brackets run smoothly on every iPhone — from the latest Pro Max back through older models. No slowdowns, no thermal pauses, just results. Macro photography. Product shots. Jewelry. Watches. Coins. Insects. Botanical specimens. Forensic detail. Whatever the subject — Zeus Focus Stacking handles depth so you don't have to. Free to download. Pro upgrade unlocks full-resolution export, Ultra 48 MP capture, AI post-process, iCloud sync, Capture Speed control, and 20-frame brackets.

Eagle Image Stacker is a local-first astronomy imaging toolkit for iPhone. Import or capture RAW, DNG, ProRAW, JPEG, HEIF, TIFF, and other supported image files, then align, calibrate, stack, inspect, and export high-quality results. Use Astro Mode for star fields, galaxies, nebulae, and deep-sky sequences. Use Planets Mode for Moon and planet workflows with ROI tracking and alignment tools. RAW Converter helps inspect and export camera files, while calibration tools support dark frames, flat fields, hot-pixel review, masks, and alignment analysis. The app is built for on-device processing. Your selected images and generated outputs remain local unless you choose to save, export, or share them through iOS. Some capture features depend on your iPhone hardware. RAW and Apple ProRAW availability varies by device.
