SpaceOver uses VoiceOver, spatial sound, haptics, etc. SpaceOver makes it possible for the blind and visually impaired(BVI) to go on a space journey. [Navigation function] - Utilizes the AR function to guide the location of astronomical objects in the solar system based on the current user's location. - Each astronomical object has its unique music, which together creates the harmony of our universe. - You can move your phone to find a specific astronomical object and enjoy the music of that object. [Search function] - You can find the object by selecting the object you want to find. - You can receive guidance on where to go through voice-over, and you can feel the location of celestial bodies through spatial sound. [Astro travel function] - If you find specific astronomical objects, you can travel to those objects. - You can enjoy the appearance of astronomical objects as a 3D model. - You can enjoy the space journey through voice-over and music.

Project Planet - an interactive map of our solar system How much would you weigh on Jupiter? Why does a day on Mercury last longer than its year? Project Planet turns space facts into a fingertip-sized journey. Scroll through all nine planets (Pluto included), feel each world's pull on your own body, and explore the numbers astronomers have spent decades collecting. Highlights - Sticky scroll across the system: from Mercury to Pluto, each planet stays centred long enough for you to take it in. - You, on every world: enter your weight and age once and watch them recalculated by each planet's gravity and orbital period. - Five rich widgets per planet: surface temperature with reference markers (Antarctica, freezing, boiling), atmospheric pressure with composition chart, travel times from Earth from walking up to the speed of light, gravitational force with everyday objects (phone, backpack, car), and an interactive pressure simulator with phase changes for water, oxygen, CO2, hydrogen, nitrogen and mercury (Antoine equation under the hood). - Six languages: Czech, English, German, Slovak, Spanish and French, auto-detected from your device. - Metric or imperial: switch instantly; weights, temperatures and distances follow your preference. - Crafted to feel like a small cosmic museum: dark cosmic theme, hand-tuned typography, subtle scroll choreography, and a right rail that lets you jump to any planet. - Built on real data: gravitational accelerations, orbital periods, NASA mean temperatures, atmospheric compositions and substance phase transitions. Requires an internet connection. The app runs as a continuously updated webview and uses native iOS capabilities such as haptic feedback to add a tactile dimension to your interstellar journey.
