AstroIndexerCompanion

See your whole deep-sky library at a glance - now with environmental insights, weather and guiding stats, and a built-in demo library to explore before your first sync.

Take your deep-sky imaging library with you. AstroIndexer Companion is the read-only mobile companion to AstroIndexer Desktop - browse every target you have photographed, anywhere, fully offline.

TRY IT BEFORE YOU SYNC A built-in demo library loads on first launch, so you can explore the app with real astrophotography data before pairing with your desktop.

YOUR LIBRARY, IN YOUR POCKET

• Every imaged object with exposure totals, frame counts and session history
• Search and filter by catalogue (Messier, NGC, IC, Sharpless, vdB), object type and narrowband or broadband filter
• Representative previews of your processed images
• Catalogue completion: how much of the Messier or NGC list have you captured?

QUALITY AND CONDITIONS AT A GLANCE

• Quality metrics per target: FWHM seeing, SNR, star counts and an overall score
• Shooting conditions: moon illumination and separation, airmass, guiding RMS
• Per-night weather: temperature, humidity, dew point, cloud cover, sky quality
• Calibration coverage per target
• Per-filter exposure allocation charts

INSIGHTS ON THE GO

• ML-detected environmental patterns (moon impact, dew degradation and more) with plain-language recommendations
• AI digest summarising what your library needs next

YOUR EQUIPMENT

• Every rig with optics, sensor, gain and offset, site and sky quality
• Backfocus train with per-component breakdown and tolerance status

EASY SYNC, PRIVATE BY DESIGN

• Pair with AstroIndexer Desktop over your own Wi-Fi via QR code or 6-digit code - your data never touches a cloud server
• Or import an exported package file - no network needed at all

MADE FOR IPHONE AND IPAD

• Guided walkthrough on first launch
• Full split-view layout on iPad

Built for astrophotographers by astrophotographers. Requires AstroIndexer Desktop (free trial at astroindexer.com) for your own data; the demo library works without it.
