The apps from Actual Concepts are designed to provide education through fun. There are 2 versions of this App - Earth & Space free version , Earth & Space. The free version of the App contains 2 simulations for free for the users to get a feel for the content.
This App helps in interactively exploring Earth and Space using real time simulations. The simulations are highly touch enabled and are designed game-like so that people would love to play around with the simulations and at the same time can gain a deeper understanding of Space science concepts.
The simulations in this App are 3D like and are designed very carefully to support multiple view points of the Earth-Sun-Moon system (Top view, Side view, Orthogonal view etc., wherever necessary). Suppose Earth is moved in top view, then its position also changes in side view correspondingly, thereby providing a very helpful & visual clarity of motion of these heavenly bodies from different views.
Touch the Moon, Earth or Planets to control and maneuver them to understand how the motions of these heavenly bodies cause seasons on earth, Tide formations etc.,
Unlike most of the apps on Space & Earth that are present out there, this App offers lot of simulations which are real time and highly touch enabled to play around with. This App is a must for your reference library if you are space enthusiast.
The simulation name and the activity that can be done on the simulation are briefed below -
1. Order of Planets in Solar System - You can place the planets in the correct order from Sun. If they are placed in correct order, they rotate! Play and Learn!
2. Earth-Sun and Moon System - You can manually set the duration for the Earth or Moon to rotate. See why it takes 28 days for the Moon to rotate around Earth,
How many times Moon rotates around Earth in a Year etc., Very interesting activities.
3. Causes of Seasons - See the Earth rotate in a 3 dimensional view and practically understand how seasons are formed at different poles.
4. Phases of the Moon - Step by Step you can touch and control the Phases of the Moon by rotating the Moon around the Earth.
5. Earth's rotation - Observe how Day and Night on Earth are formed
6. Lunar Eclipse - Find out how it appears from different parts of Earth? How is this formed? - Touch the moon to simulate Lunar Eclipse!
7. Solar Eclipse - How it appears from different parts of Earth? How is this formed? - Simulate and learn!
8. Do you know why a Lunar Eclipse cannot happen every full moon? - Understand it through this 3D simulation. Touch and rotate the Moon, Earth and find out yourself why it happens only on specific full moon days.
9. Ocean tides - Full moon/New moon - Do you know why there are spring tides and neap tides? You can touch and control the motion of moon and see how the ocean tides vary with the position of Moon - Real time simulation!
For Enthusiasts / Parents - Parents can use this app effectively to make your child practice and learn Science skills from these highly interactive & touch enabled game-like simulations that children would love to play with.
For Students - Students can perform the activities on the simulations presented on several figures.
For Teachers - This app can be used as a classroom tool to supplement teaching that enhances productivity. This app boosts your classroom productivity & provides a fun filled lab experience in your classroom

All positions can be shown in real time, or in faster animation. You can set the clock to other times in the future or past.
You can navigate in three dimensions, and zoom in and out. The orbits of the moons can be made visible. Information on the nature of the satellites is given.
A point of view Orbiting planets and moons.
The 3D parameters used in this application are based on current information known of the solar system, only the distances between the Sun and the planets, have been reduced to optimize the model.
20 Natural satellites
The largest known moons are present, as well as dwarf planets Ceres and Pluto.
I hope you like it, please rate and give me ideas on how to improve the application.
Need help picking your first telescope? Not sure what it's capable of? Why not try before you buy?!
After a series of precise mathmatical calculations, Telescope Simulator will show exactly what any planet will look like through ANY telescope!!
You can even simulate different barlow lenses or eyepieces on your currect telescope to see what it's capable of!
Select from over 50 popular telescopes from Orion, Celestron and Meade to see what they are capable of!
If your telescope is not on the list, simply tap the 'Custom' button and enter its aperture and focal length and the Telescope Simulator will do the rest!
Telescope Simulator will also simulate all the negative effects of real telescopes so you know exactly what you are buying!
Just like with a real telescope, if you magnify a scope beyond its capabilities your image will get blurry and dim.
For added effect, there is an optional 'Seeing' toggle button that factors in bad atmospheric conditions.
You can even select the Hubble as your telescope just to compare!

This application allows users to program in machine code (on Intel 8085). It can be greatly useful for students and hobbyists for learning and understanding the working of the 8085 microprocessor. Efforts have been made to make the application very user-friendly and intuitive while also providing some very useful features.
Note: Please use HLT (76) as the stopping command for a program. (A few 8085 kits have RST 5 (EF) or RST 1 (CF) as the stopping command)
- you can use this app like a dice (maximum number 6) for different games, like backgammon, monopoly, craps, hazard and others.
- you can also simulate coin flipping (maximum number 2)
Note: Random numbers have applications in gambling, statistical sampling, computer simulation, cryptography, completely randomized design, and other areas where producing an unpredictable result is desirable.
A Turing machine is a hypothetical device that manipulates symbols on a strip of tape according to a table of rules. Despite its simplicity, a Turing machine can be adapted to simulate the logic of any computer algorithm, and is particularly useful in explaining the functions of a CPU inside a computer.
