## What is AstroIndexerCompanion?

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
- Full-screen image viewer: tap any target to fill the screen, swipe between objects, pinch to zoom
- Search and filter by catalogue (Messier, NGC, IC, Sharpless, vdB), object type and narrowband or broadband filter
- Filter by imaging year and sort by catalogue, name, date or integration time
- 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 summarizing what your library needs next

YOUR EQUIPMENT
- Every rig with optics, sensor, gain and offset, site and sky quality
- Back-focus 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
- Adaptive layout that fills an iPad screen with a four-column library grid

Built for astrophotographers by astrophotographers. Requires AstroIndexer Desktop (free trial at astroindexer.com) for your own data.

## Version history (last 5 releases)

### 1.7.0 — 2026-08-24

FULL-SCREEN IMAGE VIEWER
Tap the image on any target to fill the screen. Swipe left and right to move
between targets, pinch or double-tap to zoom in, and tap once to hide the
details and just look at the photograph.

SHARPER IMAGES EVERYWHERE
Target images now load at full resolution on the detail screen and in the new
viewer. Until now the app showed the smaller grid preview even where there was
room for far more detail - the full-size version was already in the package on
your device, simply unused. No re-sync needed.

YOUR RIG, ON EVERY IMAGE
Each target now shows the setup that captured it - telescope, camera, focal
length and f-ratio - over the image and in Capture Info, rather than just the
setup name.

FILTER BY YEAR, SORT YOUR LIBRARY
Two new controls in the Library: narrow to a single imaging year, and sort by
catalogue, name, newest, oldest, or most integration time. Both work alongside
the existing catalogue, filter and object-type chips.
