Read full descriptionHide full description
Astro PM is the companion app to the Astro PM desktop software — the astrophotography project manager that plans, schedules, and automates your imaging through NINA. Pair the app with your Astro PM account and your observatory follows you everywhere. PAIR IN SECONDS Scan the QR code shown in the desktop app (Settings → Pair Phone), or enter your sync token manually. Your connection is stored securely on the device. YOUR IMAGING SYSTEMS AT A GLANCE See every enabled rig — site, telescope, and camera — with live target counts. Multi-observatory setups show each dome or pier as its own system, exactly as configured on the desktop. TARGETS AND PROGRESS Browse the cloud targets for each imaging system with their images, coordinates, mosaic layout, and status. Tap a target for its full exposure plan: per-filter progress bars, exposure length, gain, offset, binning, and accepted counts — plus total integration time captured versus planned. Priorities and progress stay in sync with the desktop app and the NINA plugin. ASTRONOMICAL WEATHER A 16-day astronomical forecast for each observing site: cloud cover by layer, computed seeing and transparency, wind, temperature and dew point, and sun/moon altitude bands with your imaging windows marked. Nights are centered so you can judge tonight at a glance. NINA REMOTE PAUSE/PLAY Running the Astro PM NINA plugin? Pause and resume your automated nightly imaging loop right from your phone — the sequencer confirms back so you know the command landed. BUILT FOR THE FIELD Target data is cached on the device, images download once and stay cached, and nothing polls in the background — the app only fetches when you open or refresh a page. REQUIREMENTS Astro PM is a companion app. It requires the Astro PM desktop application (Windows) and an Astro PM account — visit astro-pm.com to get started. NINA remote control additionally requires the free Astro PM NINA plugin. This app is free to use and does not offer or have any in-app purchases. Weather data by Open-Meteo. Satellite and forecast sources credited in the desktop app.

Verdict
The clearest difference is in-app purchases: Astro PM at none against Geo's 1. Astro PM also leads on update cadence (fortnightly vs every 12 months) and iOS requirement (15.0 vs 17.6). On price, ads and device support there is nothing between them.
