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.

Fixed an issue where opening a project from the gallery right after saving a new one could show another project's images when comparing with the original. Thanks for using Zeus Focus Stacking.

Photos taken with the phone held sideways now come out the right way up — in your gallery, in Photos, and everywhere you share them. Portrait throughout. The app stays upright wherever you are, while the camera controls keep turning with your phone so every shot is framed the way you intend. IMPROVED Your projects are now always kept at full quality, whatever your plan — the resolution limit applies only when you export or share.

NEW Ultra 48 MP — a fourth rung above Max Quality in the capture quality panel. The whole bracket is captured at the sensor's full resolution instead of 12 MP. The rung appears only on iPhones with a 48 MP-class sensor; capturing at that resolution requires Pro. IMPROVED Highlights. When a small bright point falls out of focus it spreads into a disc, and that spilled light used to reach the finished photo as a bloom around highlights. The engine now recognizes the spreading and leaves it out. Across our test brackets the halo shrank in every case where it was present, and fine detail elsewhere is unchanged. Frames that disagree. Where two frames are equally in focus at a point but the content sits in different places — a subject that shifted between shots, a reflection — averaging them showed both copies as doubled edges. On iPhones with enough memory, those regions are now taken whole from the frame that resolves them. The engine decides region by region: taking a region from one frame gives up the noise averaging of combining many, so it only does it where removing the doubling is worth more than the grain it costs. On a dark hand-held bracket it declines almost every region; on a bright, detailed one it takes almost all of them. FIXED Before a stack runs, the app now measures the memory actually available and picks the richest processing it can finish, reducing resolution rather than stopping part-way. Previously it could be terminated during the final merge.

FIXED On some devices with less memory (such as iPhone 13 and iPhone SE), the app could close during the final merge step, before your stacked photo was ready. Focus stacks now complete reliably on these devices.

FIXED On some storefronts the Pro subscription prices could load forever, making the purchase impossible. Prices now appear worldwide, and if the App Store connection hiccups the paywall shows a Retry option instead of spinning. ALSO Zeus Pro subscriptions are now available in every App Store country.
