AstroIndexer Companion · iOS & Android

Your library, in your pocket

The desktop app indexes and analyses your archive. The companion app puts the result in your hand — every object, every capture stat, every pipeline status, from the field or from the couch.

Free with your AstroIndexer library · phone and tablet

Two apps, one library

AstroIndexer is a desktop application. The companion app is a window onto the same indexed data — it does not re-analyse anything, it shows you what your desktop already worked out.

Desktop

Where the work happens

Scanning, plate solving, quality analysis, stacking and the machine-learning modules all run locally on your computer, against your FITS and XISF files.

Mobile

Where you check it

Browse the catalogue, pull up any object, and read its capture summary and pipeline state — while you are setting up under the sky, or nowhere near your desk.

Overview
Your archive at a glance.
Library
Every indexed object, searchable.
Equipment
Rigs, and how each one performs.
Insights
Patterns found in your history.
Settings
Sync and preferences.

Your whole catalogue, in one view

Search by object or catalogue, filter the list, and see the totals for everything you have indexed — objects, accumulated exposure, and how much has been through quality analysis.

  • Search across objects and catalogues
  • Filter by catalogue or by filter used
  • Library totals: objects, exposure hours, QA coverage
  • A featured target surfaced from your own archive

Every object, with the numbers that matter

Open any target and see what you have actually accumulated on it — not a folder listing, but the totals your desktop computed. Scan, Rig, QA, ML and Image each carry their own state, so one look tells you whether an object is finished or still waiting.

  • Total exposure, frame count and how many nights it took
  • The rig that captured it, named
  • Date range from first to most recent session
  • Coordinates and calibration sets on record
  • Per-stage pipeline indicators and the quality verdict
  • Object previews synced from your indexed library
