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.
