Moon Lunation vs Weather Engine

Moon Lunation shows you the Moon's phase for any date between 2000 and 2050, and now the tides it drives, all computed on your device from the actual geometry of the Sun, Earth and Moon. Moon Lunation is free. No connection. No account. No data collected. No ads, ever. TODAY The current phase, the illuminated percentage, how far through the lunation you are, and the next principal event in your local time. CALENDAR Any month from 2000 to 2050, with new moons, first quarters, full moons and last quarters marked on the local dates they occur. CYCLE Watch a lunation play out from one new moon to the next. The timeline runs between two actual computed new moons, so its length varies rather than being forced to 29.5 days. Scrub it with your finger, or play it through. TIDES, WITH MOON LUNATION PRO See today's tide curve set against the highest high and lowest low of the station's year, marked by two dashed lines, with a line of text giving each with its date. Also the next high and low tide and seven days of highs and lows, in metres or feet. Predictions are calculated on your device from each station's tidal constants, so Tides works with no connection. Tides covers about 1,250 stations around the United States and 37 around the UK and the Isle of Man, from 2026 to 2030. On iPhone and iPad it can find the nearest station from your location, or you can choose a city. On Mac, you choose a city. Keep up to five favourite places. These are astronomical predictions. Weather can change the real water level, and they are not for navigation. SOLAR SYSTEM, WITH MOON LUNATION PRO See the Sun, Mercury, Venus, Earth, the Moon and Mars in 3D, placed by the same offline astronomy. On Mac, all eight planets, out to Neptune. Drag to orbit, pinch or scroll to zoom, tap a body for its distances, and scrub the timeline to watch the planets move. Moon Lunation Pro is a one-time in-app purchase, not a subscription, and unlocks both Tides and the Solar System. If you already have Pro, or paid for Lunation or Moon Lunation before it became free, Tides is included at no extra cost. Family Sharing is on. ON MAC A native Mac app with a sidebar and inspector, keyboard control, a menu-bar Moon and desktop widgets. THE MOON ITSELF The surface is built from Lunar Reconnaissance Orbiter imagery, in a fixed north-up view of the near side. The lit region is drawn from the computed phase, so what you see is the geometry. The light now falls off toward the terminator, the edge between light and dark is soft, and the unlit side shows a faint earthshine, strongest near new moon. WHAT IT DOESN'T DO • Phases cover 1 January 2000 to 31 December 2050, and tides cover 2026 to 2030. Outside them, the app says so rather than guessing. • It is a north-up diagram of the phase, not a picture of how the Moon looks in your sky tonight. • It does not show libration, eclipses, moonrise or moonset. • Phase times are geocentric, not for your location. PRIVACY Moon Lunation collects no data: no analytics, no crash reporting, no advertising, no tracking and no account. The app makes no network requests of its own. Phases, the calendar and the cycle never use your location. On iPhone and iPad, only after you allow it, Tides uses it to find the nearest tide station; the app does not save or send it. It keeps a small count of days used, on the device, to decide when to ask the system for a review. Tides remembers your place setting and up to five favourite stations, and Clear Saved Places removes them. On Mac, Tides does not use your location. It works in Airplane Mode, on the first launch and every launch after. iPhone, iPad and Mac. Requires iOS 17, iPadOS 17, or macOS 14 or later.

**Weather Engine** Weather Engine is a professional weather visualization and forecasting application designed for users who want to understand weather beyond ordinary forecasts. Unlike traditional weather apps, Weather Engine combines numerical weather prediction, satellite imagery, radar observations, and interactive weather maps — now including full aviation altitude charts — into a single intuitive interface. Powered by NOAA Global Forecast System (GFS) data and a high-performance native weather engine, the application delivers smooth, precise visualization of atmospheric conditions directly on your device, from the surface up to the jet stream. **Key Features** - NOAA Global Forecast System (GFS) forecasts - Real-time satellite imagery - Weather radar observations - Temperature maps and isotherms - Sea-level pressure contours (isobars) - Aviation altitude mode: 850/700/500/300 hPa constant-pressure charts with geopotential height contours and level wind - Wind streamlines with animated flow, from the surface to jet-stream altitude - Relative humidity visualization - Forecast precipitation - Interactive weather timeline - Coastline and border outline overlay, so land and sea stay legible under any weather layer - Touch any location to view detailed weather information - Automatic weather layer management based on observation and forecast availability - Optimized rendering for iPhone and iPad **Aviation Altitude Mode** Weather Engine now goes beyond the surface. Slide from mean sea level up through the standard aviation constant-pressure levels — 850, 700, 500, and 300 hPa — to see the same geopotential height contours and wind fields pilots read on a real constant-pressure chart. Whether you're studying a ridge at 500 hPa or checking jet-stream wind ahead of a flight, the map adjusts contour spacing and range automatically for each level, and animated wind streamlines scale to stay legible even at jet-stream speed. **Professional Weather Analysis** Weather Engine allows users to combine multiple atmospheric variables on one map, making it easy to understand relationships between: - Pressure and wind - Temperature and fronts - Humidity and precipitation - Radar and forecast rainfall - Satellite imagery and cloud systems - Surface conditions and upper-level flow **Built for Global, Seamless Viewing** The map renders continuously wherever you look — panning smoothly across the international date line, staying correctly aligned while rotated, and covering wide regions without gaps, even when zoomed far out over an ocean or a full continent. Radar and rain tiles are rendered at higher fidelity, and the new coastline/border outline option keeps geography readable no matter how many weather layers are stacked on top. **Suitable for** - Weather enthusiasts - Outdoor activities (hiking, camping) - Sailing & fishing - Pilots & drone operators - RF and microwave engineers - Amateur radio operators - Teachers, students, and researchers **Interactive Timeline** Move seamlessly through time to explore past observations, current weather, and future forecasts. Weather layers automatically appear or disappear depending on data availability, and the altitude slider works alongside the timeline so you can track how a pressure surface evolves over the next five days. **Native High-Performance Engine** Combines Flutter with a native C++ weather engine for efficient GRIB2 decoding and smooth visualization of NOAA weather data, tuned with adaptive level-of-detail so contours, heatmaps, and wind particles stay sharp at every zoom level from a single country to a full hemisphere. **Data Sources** - NOAA Global Forecast System (GFS) - Weather Radar - Satellite Imagery **Privacy** Weather Engine does not collect personal weather data. Location access is used only to display weather conditions around your current position.
