iOS app by Shadowfetch · App Store ID 6793514388 · iOS

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

• Open primary FITS image HDUs with common integer and float bit depths
• 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
• No account, advertising, analytics, tracking, or developer-operated backend
• 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.
