AuroraPulse

Will you see the northern lights tonight? AuroraPulse answers with one number: your chance, from where you are, right now. YOUR CHANCE, NOT JUST A KP AuroraPulse combines the planetary Kp index with your geomagnetic latitude, the cloud above you and how dark the sky is. A high Kp means little under an overcast sky or at noon, and the app says so. LIVE AURORA MAP See the auroral oval from NOAA's OVATION model on a real map, where you stand in relation to it, and which way to look. FORECAST • 3-day Kp forecast with the windows when aurora could reach you • 27-day outlook for planning a trip • Compare a destination: what Kp it needs and the cloud forecast ALERTS THAT RESPECT YOU • One evening notice when aurora is forecast for your location • Optional alert 30 minutes before the peak • Geomagnetic storm and Earth-directed CME alerts, filtered to what can be seen at your latitude SPACE WEATHER, EXPLAINED Solar wind speed, Bz, X-ray flares, sunspot number and active NOAA storm bulletins, with a guide that explains what each number means. WIDGETS AND LIVE ACTIVITY Home Screen and Lock Screen widgets, a Live Activity when aurora is possible, and Siri: "What's the aurora forecast in AuroraPulse?" COMMUNITY SIGHTINGS See recent reports near you and add your own. A sighting shares an approximate location (about 10 km), never your exact position. PRIVATE BY DESIGN No ads, no tracking, no sign-up. Your location is used on your device; weather requests use it rounded to about 1 km. Data: NOAA Space Weather Prediction Center, NASA DONKI, Open-Meteo.

Earthwise – Earthquake, Tsunami, Volcano & Flood Tracker See what the Earth is doing in real time. Earthwise is a powerful global monitoring app that gives you a clear, data-driven view of earthquakes, tsunamis, volcanic activity and floods worldwide, all in one structured and easy-to-use platform. Earthwise brings together live global activity into a single, intuitive experience, allowing you to quickly understand what is happening across the planet without noise or unnecessary complexity. From seismic events and ocean activity to volcanic systems and river behaviour, everything is organised to give you instant clarity. Explore detailed, location-based insights for your current position or any place worldwide. View nearby earthquakes with magnitude and depth data, monitor volcanic activity and historical patterns, track tsunami indicators across coastal regions, and understand flood conditions through river discharge and trend modelling. The app transforms complex environmental data into clear, readable information designed for everyday understanding. Interactive maps allow you to visualise global events in real time, with filtering options to adjust density, magnitude and focus areas. Tap into individual events for deeper breakdowns and see how activity is distributed across regions, helping you identify patterns rather than just isolated data points. Flood monitoring is fully integrated, giving you access to river-level insights, discharge trends and long-range modelling where available. Earthwise helps you understand how water systems are behaving over time, not just when flooding occurs, providing a broader view of environmental conditions. The smart briefing system delivers a clean, structured overview of global activity, combined with regional insights and customisable data views. You can tailor the experience to focus on what matters most, whether that is earthquakes, floods, volcanoes or tsunamis, creating a personalised global monitoring dashboard. Earthwise is designed to inform, not alarm. It presents structured environmental data without speculation, prediction or instruction, allowing you to stay aware of global events in a calm and controlled way. Earthwise provides informational data only and does not provide safety advice, warnings or emergency instructions. Always refer to official local authorities for guidance and decision-making.
