AstronomyAtlas is the last word, premium, high-performance offline cellular planetarium software
template constructed for house lovers, stargazing hobbyists, and novice astronomers. Engineered with Flutter’s
cross-platform capabilities, AstronomyAtlas delivers a native-speed person expertise on each Android and iOS from a
single, clear codebase. Structured with clear Area-Pushed MVVM structure and Riverpod state administration, this
app supplies an entire offline-first answer for monitoring stars, constellations, photo voltaic system planet orbits, and
satellite tv for pc passes. Optimize your cellular app retailer presence within the extremely energetic science, reference, and training
niches right now!
Profitable stargazing requires correct calculations. AstronomyAtlas empowers hobbyists with a real-time 3D
Night time Sky Map that maps alt-azimuth grids and constellation connections utilizing gyroscopic sensors. Customers
can search and discover celestial our bodies by way of an offline Deep Sky Catalog powered by SQLite
(containing Messier seed objects and the NGC catalog) and preview high-resolution sky pictures over coordinate
grids by way of the DSS2 observatory photograph inspector.
Past easy sky maps, the applying incorporates a built-in Photo voltaic System Orbit Simulator. This
simulator propagates orbits utilizing Keplerian planetary components and shows real-time velocity vectors. To trace
overhead objects, the app contains an offline Satellite tv for pc & ISS Go Tracker, which calculates
trajectories utilizing SGP4/SDP4 propagation. Customers can schedule automated, offline notifications for seen overhead
passes with a single click on.
For app publishers and builders, AstronomyAtlas is totally monetization-ready and
store-optimized. It’s pre-configured with safe compile-time Google AdMob advertisements (supporting App
Open, Native, Banner, and Interstitial codecs) and a seamless in-App Buy (IAP) retailer move for
lifetime premium upgrades. Designed utilizing a quick native SQLite database and Hive settings storage, this template
ensures a low-maintenance, serverless enterprise mannequin with zero database internet hosting overhead. Launch your cellular app
enterprise within the extremely energetic astronomy and training area of interest right now with AstronomyAtlas!
