AstroIndexer Companion

AstroIndexer Companion brings your astrophotography library to your iPhone.

It is the mobile companion for AstroIndexer: a focused viewer for browsing your processed images, target metadata, exposure history, quality information, and catalogue progress after syncing from your desktop.

Browse your archive visually
Open a clean gallery of your synced targets and final or processed images. Search, sort, and filter by target, catalogue, object type, equipment, filter set, exposure time, imaging date, and quality score.

Understand every target
Each target detail view brings together the information that usually lives across folders, filenames, FITS/XISF headers, notes, and processing exports:

• final and processed image previews
• catalogue IDs and object type
• constellation and imaging dates
• total exposure time
• number of frames
• filter-by-filter exposure breakdown
• telescope and camera information
• average and best quality scores

Track catalogue progress
See how your imaging archive maps against major astronomical catalogues. Review which objects are already imaged, which are partial, and which are still missing. AstroIndexer Companion helps turn your archive into a practical long-term observing record.

Designed for offline access
After sync, your mobile library is stored locally. Browse targets, summaries, images, and catalogue completion without needing to stay connected to your desktop. No AstroIndexer-hosted cloud account is required.

Built for AstroIndexer users
AstroIndexer Companion is not a raw frame browser, stacking tool, or mobile image processor. It is a dedicated companion viewer for the AstroIndexer desktop workflow: your desktop remains the source of truth, and the mobile app gives you a fast, practical way to review your astrophotography library wherever you are.

Key features:
• local AstroIndexer library sync
• gallery of synced targets and processed images
• target search, sorting, and filtering
• exposure and filter summaries
• telescope and camera metadata
• quality score overview
• catalogue completion tracking
• offline mobile access after sync

AstroIndexer Companion helps astrophotographers move beyond folders and filenames. Your imaging history becomes visual, searchable, measurable, and easier to review from your phone.

Requires AstroIndexer desktop and a synced mobile library export. Available data depends on the metadata and processed images present in your AstroIndexer library.
