About Astrosift: FITS Workbench

Astrosift: FITS Workbench is a focused, fully on-device app. A private FITS image and header workbench for HDU inventory, monochrome previews, stretch controls, pixel statistics, star-candidate measurement, and observation handoff.

KEY FEATURES

- Inspect 80-character header cards and extension inventory
- Preview monochrome data with linear, square-root, or logarithmic stretch
- Measure background, saturation, centroid, FWHM, and candidate peaks
- Export a contact sheet, pixel statistics, and observation report
- Complete bundled sample and local comparison workflow
- Local PDF report and Apple system share export
- Original offline technical reference library

ONE-TIME AND PRIVATE
- One paid download; no subscription or in-app purchase

- Core features and bundled content work offline
- Work remains on device unless you deliberately share or export it through an Apple system interface

Astrosift is an inspection and planning tool, not a calibrated scientific pipeline. Verify photometry, world coordinates, debayering, and observatory-specific conventions elsewhere.
