AstraLog

AstraLog is your pocket planetarium — a calm, beautiful companion for everyone who loves looking up at the night sky.

Open the Sky screen and explore an interactive star map where constellations glow as connected clusters of stars over a deep, drifting night sky. Tap any constellation to watch its figure trace itself out, star by star, in a glowing connect-the-dots animation, then read the myth behind it and learn how bright it is and when it is best seen.

Browse the Constellation Guide to search the catalogue, mark your favourites, and see at a glance which constellations are visible from your hemisphere. When you spend a night under the stars, log it in your Observation Journal: rate the sky clarity, note the conditions, and jot down what you saw. A weekly chart and a night streak keep your stargazing habit alive.

Never miss a celestial moment again. The Sky Events timeline counts down the nights until the next meteor shower, eclipse and planetary conjunction, with a tap to set yourself a reminder.

AstraLog works completely offline, respects your privacy, and looks stunning in both a luminous day theme and a true midnight dark theme. Whether you are a curious beginner or a seasoned skywatcher, AstraLog helps you learn the sky, remember your best nights, and always know what is coming next.
