| Spec score · Focus Stacking Software | 7.9 (#9) | 7.5 (#18) |
| Alignment | Automatic alignment includes feature matching and subpixel refinement, with options for focus-breathing correction, homography, mesh warp, and manual alignment seeding. | It aligns neighboring frames to sub-pixel precision and handles shift, rotation, exposure differences, and focus breathing. |
| Command line | The focus-stacking engine also ships as a command-line tool with parameter flags for scripting batch processing. | Pro includes the fusionstack command-line tool for batch and scripted runs. |
| Maker | The terms identify the publisher as Suriyanarayanan R Srinivasan of Aduku Labs, and the site says the product is made in India. | The product page identifies the maker as Rekall Software Solutions. |
| Purpose | Aduku Stacker combines focus-bracketed photographs into one sharp image for macro, product, landscape, and microscopy photography. | Rekall Fusion aligns focus-stack frames and fuses them into a single image sharp from front to back. |
| Retouching | Users can paint from aligned source frames, erase strokes, and undo or redo retouching; the app does not yet have a clone tool. | Pro includes a non-destructive brush for changing which source frame supplies a region of the result. |
| Support | The maker lists [email protected] for questions and support, and says it has no obligation to provide support, maintenance, or updates. | The product page links to a user guide and settings reference that explain setup, settings, and statistics. |

In their own words
Aduku Stacker
Aduku Stacker combines photographs taken at different focus distances into a sharp image, for macro, product, landscape and microscopy photography. The free app offers five merge methods: Wavelet, Pyramid, Weighted, Hybrid and Depthmap. Its default workflow processes images at 16-bit and uses 32-bit floating-point merge calculations, with memory-bounded batching for deep stacks. Automatic alignment uses feature matching and subpixel refinement; options include focus-breathing correction, homography, mesh warp and manual alignment seeding. It imports JPEG, PNG, TIFF, BMP, HEIC and DNG, and exports JPEG, PNG, TIFF, linear DNG and depth maps. Proprietary RAW files may require Adobe DNG Converter on macOS. Retouching lets users paint from aligned source frames, erase strokes and undo or redo, but there is no clone tool. Processing is local and does not require an internet connection. It runs on macOS 13 or later and 64-bit Windows 10/11; 8 GB RAM is sufficient for most stacks, with 16 GB recommended for deep 16-bit RAW stacks.
