The free App ensures that you will always think of everything and, if necessary, put you in the position to plan well in advance. These are some of the features that we have integrated:
- Management of the residents
- Tips and planning of the feeding
- Water values
- Maintenance tasks, such as the cleaning of the tank, changing of the water, pumps and filters
- Photo library
In this way, you can be on top of everything and can rest assured that your fishes are in good hands and are thriving magnificently. So that no information is lost, you can save all the data not only locally, but also on an Android backup facility (not available with some manufacturers).
The Aquarium Manager is one of the most comprehensive tools currently available on the market. It is suitable both for hobby aquarists, as well as for all those who cannot take responsibility for their own Aquarium. It is also particularly convenient if you want to go on holiday: Because the care-taking steps unfold at a glance, you can give your aquarium keeper precise instructions for days and weeks while you are physically away!
Although we wasted no effort in the development to anticipate everything and all needs, we always appreciate feedback so that we can become even better. Our goal was to create an individual, comprehensive database to assist you keeping your aquarium optimally, regardless whether you are physically present or absent.
Please note: For an optimal experience a Tablet of at least 7 inches is recommended.
We hope you enjoy our App!

1. Always check angle units and numeral bases: trigonometric functions, integration and complex number computation work only for RAD!!!
2. Application contains ads! If you want to remove them purchase special option from application settings. Internet access permission is needed only for showing the ads. ADS ARE ONLY SHOWN ON THE SECONDARY SCREENS! If internet is off - there are no ads!

NOTE ABOUT INTERNET ACCESS: Calculator++ (version 1.2.24) contains advertisement which requires internet access. To get rid of it - purchase a version without ads (can be done from application's preferences).
How can I get rid of the ads?
You can do it by purchasing the special option in the main application preferences.
Why Calculator++ needs INTERNET permission?
Currently application needs such permission only for one purpose - to show ads. If you buy the special option C++ will never use your internet connection.
How can I use functions written in the top right and bottom right corners of the button?
Push the button and slide lightly up or down. Depending on value showed on the button action will occur.
How can I toggle between radians and degrees?
To toggle between different angle units you can either change appropriate option in application settings or use the toggle switch located on the 6 button (current value is lighted with yellow color).
Also you can use deg() and rad() functions and ° operator to convert degrees to radians and vice versa.
268° = 4.67748
30.21° = 0.52726
rad(30, 21, 0) = 0.52726
deg(4.67748) = 268
Does C++ support %?
Yes, % function can be found in the top right corner of / button.
100 + 50% = 150
100 * 50% = 50
100 + 100 * 50% * 50% = 125
100 + (100 * 50% * (25 + 25)% + 100%) = 150
100 + (20 + 20)% = 140, but 100+ (20% + 20%) = 124.0
100 + 50% ^ 2 = 2600, but 100 + 50 ^ 2% = 101.08
Does C++ support fractional calculations?
Yes, you can type your fractional expression in the editor and use ≡ (in the top right corner of = button). Also you can use ≡ to simplify expression.
2/3 + 5/9 ≡ 11/9
2/9 + 3/123 ≡ 91/369
(6-t) ^ 3 ≡ 216 - 108t + 18t ^ 2 - t ^ 3
Does C++ support complex calculations?
Yes, just enter complex expression (using i or √(-1) as imaginary number). ONLY IN RAD MODE!
(2i + 1) ^ = -3 + 4i
e ^ i = 0.5403 + 0.84147i
Can C++ plot graph of the function?
Yes, type expression which contains 1 undefined variable (e.g. cos(t)) and click on the result. In the context menu choose 'Plot graph'.
Does C++ support matrix calculations?
No, it doesn't

King Calculator recently got accepted to the Google in education program and being incorporated in schools who use Android devices as educational tools.
King Calculator offers a simple layout for common operations and a scientific layout for when you need a scientific calculator which also comes with a function graphing engine.
Excellent for school work, college studies, science and engineering.
Simple calculator layout offers:
• Basic arithmetic, Exponentiation, Square root.
• Percentage calculation.
• Classic memory functionality or Casio style MRC / M+ / M- buttons and memory capabilities.
• Calculation History.
Scientific calculator layout offers:
• Trigonometric function ( Sine, cosine, tangent, arcsine, arcosine, arctan, hyperbolic • sine/cosine and tangent)
• Square and cubed root (or any other root using the exponentiation button)
• Factorial and modulo operations
• Logarithmic functions
• Absolute value function and more.
• Plotting/Graphing functions.
calculator with percentage
•A resizeable widget with arithmetic, percentage button, and fractions.
•Expression (formula) based input.
•Fraction input and output with conversion to proper fraction, mixed fraction and decimal. Even the quadratic or cubic root functions, for instance, will return fractions when the answer can be written as a fraction.
•Full history with buttons that load old results, in case you need to start over from a previous point.
•Unlimited memory slots that can be named and are always displayed on screen.
•Multiple input fields except on small phones. This let's you do short side calculations without losing your place.
•Pre-packaged functions for quadratic equations as well as many geometric formulae.
•Buttons that store user defined functions that are created by binding an argument to a binary operator.
•Visualization of multivalued complex functions (roots, inverse trigonometric, logarithm)
•Visualization of quadratic and cubic functions
•Visualization of angles returned from inverse trigonometric functions.
•Complex numbers are very easy to work with, and all functions work with complex numbers where they are defined (inverse hyperbolic cosine, for instance).
•There is a fourth layout for small phones that is not shown in the screen shots.
•A unit conversion utility that lets you build arbitrary composite units. Conversion factors are written to the history, so you can bind the factor with multiplication to do the same conversion many times.
The layouts are designed to be ergonomic for each of four device sizes in portrait and landscape. Here are some examples of what we've done to make the calculator easy and speedy to work with:
•On small tablets in landscape, the keys are split so you can operate the calculator with two thumbs.
•On small phones, the numeric keypad is right under your thumb when holding the device with one hand.
•Square root, square, inverse and negation are all close to the numeric keypad.
•On small tablets, the long "NHN-1" button is a gesture recognizer that lets you scroll the six input fields with your left thumb. That way you don't have to let go of the device with your right hand to click an input field.
The main advantages of this calculator is:
- Simplicity and ease of use.
- Stylish design.
- Ability to change skins (colors), you just need to click the menu and go to the settings.

Number of digits in the calculation results because it is a 12-digit
Unless such person to calculate the national budget,
I think basically okay.
While maintaining beautiful image quality,
as far as possible, the size of the app itself
We have to strive to reduce.
※ In order to raise the production costs of the new app,
I have entered the ad.
That it is an inconvenience to our use
I apologize m (__) m

A simple calculator, the display of which indicates expressions and gives easy operation for editing.
The calculator PanecalST includes features below:
*Four arithmetic operations, root, percentages, and tax calculations
*Calculations with parentheses
* Memory, M+, M-, MR, MC
*Scroll up/down lines
*Easy editing by using a cursor operation
* Cut, copy, and paste
*Expressions history and answer history
*Configurable grouping separator and decimal point
Four arithmetic operations:
1 + 2 - 3 × 4 ÷ 5 = 0.6
√( 2 × 2 ) = 2
500 + 20% = 600
500 - 20% = 400
500 × 20% = 100
100 ÷ 500% = 20
500 Tax+= 525
525 Tax-= 500
( 1 + 2 ) × ( 3 + 4 ) = 21
( 1 + 2 ) ( 3 + 4 ) ( 5 + 6 ) = 231
Grouping separator and decimal point:
123,456,789.1 + 0.02 = 123,456,789.12
123.456.789,1 + 0,02 = 123.456.789,12
