Read full description

GlobeViewer Moon is an interactive and three-dimensional representation of the entire moon surface. The globe rotation view provides an overview of all the existing designations for various surface features. If you are interested in a specific region, an even higher resolution 3D map view can be loaded in order to take a close look at the craters, grooves and other features. There are four map modes available (elevation display, photo illustration, a combination of both and a grey texture for the telescope mode). These views were created from data from NASA's Lunar Reconnaissance Orbiter. In addition, surface details (normal maps) have been obtained from the elevation data for the display, which can be combined with all map modes. Even the smallest craters, elevations, grooves and gorges are visible on the map. The lighting in the 3D map view is designed in such a way that the light can be directed into the crater from all directions. This is used to improve the visibility of height structures in the craters and is not intended to represent the real lighting situation. Realistic lighting that includes the ecliptic was also dispensed with in the globe view in favour of the visibility of the polar regions. In telescope mode the lighting is a realistic simulation including Moon phase and libration movement. So the app becomes a useful tool for telescope users. The app will recieve lot of updates in the future - this way, user feedback should flow into the further development. If you have any suggestions or ideas for further functions in the app, please contact us using the contact form on our website. We are looking forward to your feedback.

The Eclipse App is a high-fidelity astronomical tool engineered for observers who demand absolute accuracy as well as beginners who need a guide through the exceptional experience of their first total solar eclipse. Powered by the latest 3D computational models developed by the Besselian Elements Team, this App provides accurate sub-second eclipse contact timings using lunar limb profile corrections. Whether you are a professional researcher, an astrophotographer, or a dedicated eclipse chaser, this app provides the rigorous data necessary for a successful expedition, from interactive map useful for planning, to simulating the countdown and exercise with the equipment, and for real time tracking in case you are moving in search of the right spot. Core Features: โ€ข Precision Timing Engine: Real-time calculations of Contact Times based on your exact GPS coordinates โ€ข Interactive Mapping: High-resolution path-of-totality overlays including umbral limits an the center-line. The IQP method accounts for the topography on both the lunar limb and at the observer site, as well as relying on an improved value for the eclipse solar radius (959.95" ยฑ 0.05", based on research by the Besselian Elements Team). The eclipse center-line and the northern and southern limits of the umbral shadow path also account for these three factors. Hence, these lines are not smooth lines, as in most publicly-available eclipse maps, but are noticeably jagged. Two lines are presented at each path limit corresponding to two values of the eclipse solar radius (959.90" and 960.00") in order to display a region of uncertainty rather than a single limit line. โ€ข Live Audio Synchronization: A sophisticated voice-cue system that announces critical contact phases and astronomical phenomena (e.g., shadow bands, corona visibility, and solar filtration changes), allowing you to keep your eyes on the sky or your equipment. โ€ข List of phenomena to observe during the eclipse at every step, so that you can be reminded to watch at the right time Designed for the Rigorous Observer: The Eclipse App eliminates the margin of error inherent in simplified models. Prepare for the next Great Eclipse with the most scientifically robust tool available on the App Store.

Verdict

The call

The clearest difference is price: Eclipse Countdown at $1.99 against GlobeViewer Moon PRO's $26.99. Eclipse Countdown also leads on update cadence (monthly vs every 6 months). GlobeViewer Moon PRO's advantage is iOS requirement (12.0 vs 15.1). On ads, in-app purchases and device support there is nothing between them.
