NightWatch Astro
A field companion for amateur astronomers and astrophotographers: sky, weather, compass, and track recording, all in one app.
NightWatch Astro started as a personal project: the app I wished I had in my pocket every time I went out to observe the sky — something to plan the evening, orient myself in the field, and keep track of where I'd been. I built it piece by piece, for myself — and then decided to make it available to everyone, in case it turns out to be useful to you too.
Built around an evening under the stars
Moon phase, sunrise and sunset, astronomical twilight, and rise/set times for Venus, Mars, Jupiter, and Saturn. Pick a location and any date, including future ones.
Hour-by-hour weather conditions plus a rough estimate of how promising the evening looks.
Sensor-based compass and bubble level, for orienting yourself and setting up a tripod.
Save your observing spots with coordinates, photos, and notes.
Record a route in the background, even with the screen off, and export it as GPX.
An OpenStreetMap-based map with your locations, recorded routes, and live GPS position.
The longest shutter speed before stars start to trail, based on your lens and sensor.
Red-on-black display to preserve your night vision outdoors.
No ads, no accounts, no tracking. Your data stays on your phone — available in English, Italian, French, Spanish, and German.
Developed by Augusto Amoroso.
