The calculations are of a high enough accuracy for almost all amateur astronomy applications.
Due to the fact that astronomy is often best when far from civilization where mobile signal may not always be reliable. Therefore, this app is (almost) completely self-contained and does not require any internet connection for most of the information available. The only exceptions to this are the SOHO solar images and NGC/IC, Messier, Caldwell and Binary star images and weather forecast which are loaded dynamically, as well as the refreshing of satellite, comet and near-earth asteroid data.
Night mode turns the display red for night observations without having to ruin your night vision.
The Sky Map makes use of the direction sensors of the device to show the sky above (or below you). Most of the features can be toggled in the settings. The Sky Map also allows you to turn on the device's camera to see the view behind the device with the sky map superimposed over it.
The direction sensors of the device may need to be calibrated if the map appears to be pointing in the wrong direction. To calibrate the device's sensors wave the device in a figure-8 pattern. If the direction is still off, then the direction calibration can be adjusted manually by changing the setting in the Settings screen.
The observation log, allows you to save observations in the applications, as well as manage a list of astronomical equipment and observing locations. This equipment is also available for use in the Telescope Calculator.
Most of the data screens have an option to share the data via email, or other similar apps able to accept HTML content.
The Astronomical Time is also available as a Home screen widget. To use the widget, the app needs to be installed onto the internal storage instead of the SD card, otherwise it will not be available.

Some permissions are required for correct functioning of the app:
Location - used to determine user location throughout the app
Camera/Microphone - used to allow camera background in skymap. The microphone is never used but this permission is bundled with camera.
Photos/Media/Files - used to allow proper functioning of the full screen images and caching of images
Network access - used to do online searches, and downloading comet, asteroid and satellite data, object images and geocoding.
The app is jam-packed with features:
- Observe the sky with the skymap, planisphere, aurora forecast, polar finder, weather forecast, daylight map, Moon and Mars maps, SOHO images, Jupiter and Saturn's moons, Moon and Sun calendars and what's up.
- Detailed object information on the planets, constellations, comets, exoplanets, meteor showers, near-earth asteroids, satellites, as well as the full NGCIC, Caldwell, Messier, 6th catalog of Visual Binary Stars by the USNO and General Catalog of Variable Stars catalogs, as well as a SIMBAD search.
- Calculate angular separation, atmospheric refraction, magnitude, coordinate conversions, visual limiting magnitude, precession, redshift, and telescope airy disc, f-ratio and magnification
- Astronomical references, glossary, HR diagram and stellar classification.
- Astrophotography tools for exposure time, CCD resolution, Untracked exposure time and optimal f-ratio.
- Emphemerides for eclipses, equinoxes, conjunctions and oppositions, the sun, moon and planets

With the new free-flight option, you can take direct control and fly the spaceship yourself and become the pilot. Accompanied by a rumbling engine, you’ll be swooping through the asteroid belt, diving through the gas giant Saturn’s rings and surfing the upper atmosphere of planets. It’s the next best thing to a space walk!
The 3D models in this app are based on photos taken by NASA spacecraft and ground based telescopes. Because some of the moons around the gas giants have only been visited once or twice, we may have partially complete images. Missing surface detail for these objects is estimated from what can be seen.
In this solar system simulator you can explore the brilliant blue-green Uranus, knocked onto its side by a massive collision. Visit the proto-planet Ceres which makes up one third of the mass of the asteroid belt. Marvel at Neptune's moon Triton which orbits in the opposite direction to Proteus. Take in the sights of the Jupiter's heavily scarred moon Callisto, its surface pockmarked by countless impact craters.

Remember building a solar system in high school? Cups and papier-mache balls are in the past, because Solar Walk is an interactive orrery that shows all planets and satellites of the solar system in their correct positions in real time.
This 3D solar system model lets you navigate between planets, see their positions on a specific date, explore how they move and why. You will see the entire Milky Way galaxy from a far and zoom in to study all the planets and satellites in close-up, learn their trajectories, inner structures, history of their exploration, and geography.
Every planet has extensive information: size, mass, orbital velocity, exploratory missions, thickness of structural layers, and composition of atmosphere.
“Can’t-miss app.” - Mashable
“Solar Walk serves up a visually impressive 3D model of our solar system. Set against a haunting, atmospheric soundscape, the app shows planets and satellites in their correct positions, and offers mini movies, facts and other related tidbits.” - TNW
“This jaw-dropping app provides a wholly interactive 3D model of our solar system, one that’s had me hooked for days. It’s the kind of thing you can imagine a science teacher using in the classroom of the future — except that we don’t have to wait.” - CNet
“Zoom from Mercury to Pluto (which makes the cut in this app), passing each planet’s moons along the way. Because Solar Walk knows what time it is, the planets are in proper orientation to the Sun: Earth is dark where it is currently night and gradually lightens to daytime on the other side.” - The New York Times

Extremely easy! Just launch the application to obtain an instant overview of the planets surrounding you. You're in the middle of the screen, on Earth, and the planets are being displayed around you. If a planet is above the Compass Ring and is highlighted, it's visible. If the planet is below the Compass Ring, towards the center of the Earth, it is shadowed and below your horizon. Navigate to the stars just be touching the spaceship.
With a simple screen touch you switch to a text view listing all planetary positions. (Direction, altitude and the phase of the inner Terrestrial planets and the Moon)
Hit the 3D Planet icon for a detailed 3D view of planet/moon texture.
(The paid version, Planet Finder +, comes with an advanced Augmented Reality Camera: Just point your phone to the sky and Planet Finder + will instantly switch to Augmented Reality Mode. Spot planets and stars through your mobile camera, take a snapshot and share via facebook, email, twitter or MMS!
Interact with the Augmented Reality View by activating its Player. Play, pause, rewind and fast forward the Solar System. This will render the trajectories of the planets and the moons of Jupiter and Saturn.)
If you have a new smart phone, it most likely has a Gyroscope Sensor. Planet Finder uses this sensor in combination with your accelerometer and magnetometer. This means that Planet Finder quickly responds to your movements providing a stable image and accurate readings.

* In the first screen - You have to enter your weight and date of birth
* In the following screens you will know your weight and your age(in days and years) in different planets
* Your weight is different in each planet since the gravitational force of each planet is different, so for each planet you will know what its gravitational force is
* Each planet’s rotation duration(day&night) and the time taken to revolve around the Sun(year) is different. You will know how long a day and year of each planet is
* This app shows how many Earths can each planet hold inside it. This will give an idea of how big each planet is compared to Earth
* This app also reads out interesting facts about each planet
* This app has details for all the 8 planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. It also shows information about the Sun and the Moon.
This app is dedicated to India’s successful Mars mission MOM(Mars Orbiter Mission) also known as Mangalyaan.

Here’s what you get.
Astronomy news - get interesting in-depth astronomy news articles delivered daily to your phone or tablet. We gather news, images and videos from genuinely authoritative and interesting sources such as Universe Today, SPACE.COM, the Hubble space telescope, and NASA.
Astronomy pictures – yes, you get captivating photos via the famous NASA image of the day. But why stop there? Through the app you can also see space photography from the Hubble telescope. Unlike the NASA photos which cover a variety of subjects, the Hubble telescope images focus mostly on the night sky, retrieving information about distant galaxies, planets and stars.
Astronomy articles - Read stories not just focusing on the US, but also international partners like Russia, China and the UK. Such stories often contain interesting facts, quotes, photography and links to videos. They cover subjects such as: observatories, astronauts, test pilots, telescopes and NASA missions.
Disclaimer: we do not own or claim to own any of the content distributed through our app. These are our personal favorite sources that we think combine informative content with ease of understanding. Easier to see them in one spot than to surf all around the web.
NASA or The National Aeronautics and Space Administration is the agency of the United States government that is responsible for the nation's civilian space program and for aeronautics and aerospace research. Most U.S. space exploration efforts have been led by NASA, including the Apollo moon-landing missions, the Skylab space station, and later the Space Shuttle. At present NASA is supporting the International Space Station and is overseeing the development of the Orion Multi-Purpose Crew Vehicle and Commercial Crew vehicles.
The most notable NASA activities are its space flight programs, both manned and unmanned. The latter can be either independent, carrying scientific equipment, or supportive, testing equipment for manned flights. In the beginning, NASA’s missions focused on the space race with the Soviet Union, which won the first round, but later USA took the initiative and won the final race to the Moon.
Hubble Space Telescope
The Hubble Space Telescope is a space telescope that was carried into orbit by a Space Shuttle in 1990 and remains in operation. In low Earth orbit, Hubble's four main instruments observe in the near ultraviolet, visible, and near infrared. The telescope is named after the astronomer Edwin Hubble.
Hubble's orbit outside the distortion of Earth's atmosphere allows it to take extremely high-resolution images with almost no background light. Hubble's Deep Field has recorded some of the most detailed visible-light images ever, allowing a deep view into space and time. Many Hubble observations have led to breakthroughs in astrophysics.
Hubble is the only telescope designed to be serviced in space by astronauts.
