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!

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.
++THE VERSION NOW AVAILABLE HERE IS OF THE NEW 'SIMPLATES ULTRA' version which is a great leap forward in terms of plate coverage to the previous generation of SimPlates. Moreover, we have now addressed all of the known issues with the app on every Android platform that we have encountered. The app looks and works great -- we sincerely thank those early purchasers who patiently worked with us through niggles in early versions and offer a virtual kick in the behind to the one guy who wrote us a bad review rather than allowing us to promptly help him. Thank you all for the great feedback and kind words about SimPlates on simulator forums. We're glad you're enjoying the massive number of plates (way more than any other sim product has - including expensive subscription bases services) and we continue to update the plate database further with more plates still.
!!! AS SOON AS YOU GET THE APP DO A DATABASE UPDATE CHECK FROM THE MAIN MENU TO GET THE LATEST AND GREATEST !!!
The basic way that you use SimPlates is just like pilots from those flying small Cessnas to those flying Boeing and Airbus airliners do every day. As you virtually approach an airport on your computer, bring up its corresponding plates in the SimPlates app. Use the plate as a guide in flying the approach to landing - just like a real world pilot would. SimPlates is useful for virtual pilots of many desktop flight simulation programs, including Flight Simulator (all versions including FSX, FS2004, and MS-Flight), X-Plane, and more.
While SimPlates are real-world plates, they are NOT SUITABLE FOR REAL WORLD FLIGHT OPERATIONS and MUST NOT BE USED FOR REAL WORLD FLIGHT OPERATIONS OF ANY SORT. As SimPlates is intended for flight simulation entertainment use, the plates are not kept up to date with real-world aviation changes (worldwide subscriptions for real-world current data over $2000 per year elsewhere!). However, for serious flight simulation entertainment use, the massive collection of plates represents incredible value and capability.
SimPlates includes over 70,000 real-world IFR plates, including approach plates, SIDs/STARs (Departures/Arrivals), Airport Diagrams, Approach types include ILS, VOR, VOR/DME, NDB, LLZ, SDF, GPS, TACAN, Helicopter and Visual. With so many plates, SimPlates provides very good worldwide coverage. For most countries and major airports of the world, if you are looking for a plates, SimPlates will likely have it. However, the coverage is not universal - please see http://www.dauntless-soft.com/products/simplates/airportlist.asp for the current list of inclusions.
Supplemental features include an integrated WORLDWIDE Airport/Facilities directory and a worldwide NAVAID (Navigational Aid) directory.
Simplates' friendly interface makes it easy to find exactly the plate or information you are looking for quickly. As the totality of plates exceeds a whopping 100gb, the plates themselves are not included with your initial download from the AppStore. Rather, they are downloaded on demand when you select them in the app – this generally takes only a few moments per plate, but does require you to be online. Any plates you have downloaded into SimPlates remain on your device (unless cleared) so that you can continue to use them even while offline.

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.

Derived Unique Key Per Transaction (DUKPT) is a key management scheme in which a cryptographic key is derived for each transaction. In order to use a key derivation transaction, it is used a initial key known as Based Key Derivation (BDK) and also a public value called Key Serial Number (KSN).
Crypto Tool DUKPT is a simulator which performs the derivation of a key per transaction as if it were a capture device. The use of 3DES encryption allows the simulation of encryption PIN (password), data and MAC calculation.
It also allows the simulation of the host environment, being able to decipher the encrypted data on a device or in the simulator.
For PIN encryption uses the standard PIN Block ISO-0.
Allows to load data files to facilitate the process of input data.
It also allows the data calculated to be saved in a file for future use.
In case of data inconsistency calculated, please send us an email for analysis.

This little educational app helps you better understand the principles of a single-tape Turing machine. You create a list of rules, fill the tape and choose the initial state of the machine. Then you can step by step follow the changes of the program configuration, or go directly to the final point. The application contains two examples that help to understand its functioning.
- Saving and sharing between devices
- Simple interface
- Two examples are ready to run
The app may contain minor bugs; let me know if you find one
This fun and educational app teaches you about the mysterious world of cryptography. It helps you to understand ciphers and keys, and enables you to create encrypted messages that you can share with your friends.
You'll learn about four encryption techniques:
You'll have a fun and interactive way of building your own messages using each technique, as well as learning the history behind their use.
Once you've created a message, you can share it with your friends and see if they can decrypt it... It's up to you how much help of information you give them!
