- NASA's SDO captures the Sun every 12 seconds in 12 wavelengths, revealing layers from a 5,000 K surface to 10-million-degree flare plasma.
- Lumara app uses Jean Meeus's Astronomical Algorithms to calculate moon phases, illumination, rise/set, and distance offline with professional accuracy.
- The app tracks solar flares (B→C→M→X), coronal mass ejections (up to 3,000 km/s), and geomagnetic storms (G1–G5) in real-time via NASA's DONKI.
- Features include offline moon data, solar timelapse videos, 4K zoom, no accounts, no tracking, no ads, and free access forever, with user data staying on-device.
- Solar and lunar images are fetched directly from NASA/ESA servers (updated every ~15 minutes), and location data is stored only on-device without GPS transmission.
- Developed by Beeswax Pat, a U.S. Army veteran indie developer, with iOS coming soon and Android live, all features are free with no premium tiers.
