Plan a Milky Way shoot anywhere on Earth — no signal, no account, no subscription.
AstroShoot Pro is an offline astrophotography planner and night sky exposure calculator for photographers who shoot where phones stop working: mountain ridges, deserts, coastlines and dark sky reserves. Every calculation runs on your device from GPS, compass and the clock. Nothing is fetched. Nothing is uploaded.
Pay once. No ads, no subscription, no in-app purchases, ever.
🌌 OFFLINE MILKY WAY TRACKER
See exactly when the Milky Way's galactic core rises, peaks and sets tonight, and how high it climbs from where you stand. The full altitude curve is drawn across the night, so you can tell at a glance whether the core clears your horizon early enough to be worth the drive. Plan any future date for a trip, or type in coordinates before you leave home.
🌓 SUN, TWILIGHT & MOON — WHAT MOST PLANNERS MISS
The Milky Way only records cleanly once the sky is astronomically dark and the Moon is out of the way. AstroShoot Pro gives you sunset, blue hour, nautical and astronomical twilight, plus moonrise, moonset and exact moon phase — then combines all of it into one answer: your darkest shooting window tonight, in hours and minutes. No window? It tells you why: moonlight, daylight, or a latitude where the night never gets fully dark.
🧭 LIVE COMPASS BEARING
Point the camera the right way in seconds. The bearing dial fuses compass, accelerometer and gyroscope, corrects magnetic declination with the offline World Magnetic Model, and says it plainly: "Turn 34° right, tilt up 12°."
📐 STAR EXPOSURE CALCULATOR — 500 RULE + NPF RULE
Stop guessing your shutter speed. Enter focal length, aperture and sensor to get the longest exposure before stars trail, using both the classic Rule of 500 and the accurate, resolution-aware NPF Rule. Presets for Full Frame, APS-C (Nikon, Sony, Canon), Micro Four Thirds and Medium Format, or enter a custom sensor.
🔭 FRAMING & FOCUS
Field of view for any lens, so you know before setting up whether the arch will fit — and how many frames a panorama needs if it will not. Plus hyperfocal distance and depth of field, so foreground and stars are both sharp.
⭐ POLAR ALIGNMENT ASSIST
Align a star tracker to the celestial pole with your phone: guided steps, a live dial, and the Polaris reticle clock position for right now.
☄️ METEOR SHOWER CALENDAR
All nine major annual showers, with radiant altitude calculated for your latitude and an expected hourly rate from where you actually are — not a generic list of dates.
📓 SHOT LOG
Save what you shot and what worked. Each note fills in location, camera, core position and moon phase automatically, so you are not typing in the dark. Export as text any time.
🔴 RED-LIGHT NIGHT MODE
The whole interface is deep red on true black. Not a dark theme — red light leaves your night-adapted vision intact, the same reason astronomers use red torches. On OLED it barely touches your battery.
WHO IT IS FOR
• DSLR and mirrorless shooters doing Milky Way, star trail and nightscape photography
• Anyone travelling to remote dark sky sites with no mobile signal
• Star tracker owners who need fast, repeatable polar alignment
• Smartphone astrophotography beginners who want the maths done right
WHAT YOU NEED
• A phone with GPS, compass and gyroscope (most modern Android phones)
• A clear view of the sky for best GPS and compass accuracy
• Nothing else — no account, no sign-up, no internet
YOUR PRIVACY IS NOT THE PRODUCT
AstroShoot Pro has no internet permission at all. Not restricted, not optional — the permission is absent, so the app physically cannot send your location anywhere. No ads, no analytics, no trackers. Your coordinates, camera profiles and shot log never leave your phone.
Works on phones and tablets, portrait and landscape.
Built by a photographer who actually stands on cold hillsides at 2 a.m. Feature requests welcome.
Milky Way tracker & astrophotography exposure calculator. Works 100% offline.
