Implicit multiplication missing Not supporting implicit multiplication is a TOTAL pain! Really?!!! Uninstalling.
Eric Kumlin
Basically unusable The "x" button does nothing and there's no backspace button. This isn't really usable in its current form.
Frank van Caspel
Does it all Great colorcoded interface, and allows use of parenthesis (as any graphing calculator should).
Erik Felix
EXCELLENT! While this app is still very young, it already does a lot and it does it great. I sent a few suggestions to the dev and got a quick response saying some of my suggestions will be in incorporated, so response to feedback is great as well. This must be one of the best calculator apps on the market and I can recommend it too anyone who needs one.

Listen Read Device Only Added Installed This powerful graphing calculator lets you graph functions, parametric equations and point sets using Cartesian or Polar coordinate system. The graphing calculator automatically switches to function, parametric or point set modes according to the form of the expression  for details refer to the builtin instruction accompanying this graphing calculator.
Examples
Function:
• f(x) = xsin(2x) intvl=(∞, ∞). (You don't have to type in the interval 'intvl=(∞, ∞)'; the graphing calculator appends it when you press the Graph button. You can change the endpoints as desired.)
• Polar: f(θ) = 3sin(2θ) intvl=(0, 2π). (You can use x for θ; the graphing calculator replaces x's by θ's when you select polar coordinate system).
Parametric Equation:
• p(t) = 3cos(3t), 3sin(2t) intvl=(0, 2π). (You can use x for t.) Note: enter x(t) and y(t) separated by a comma (no enclosing parentheses around p(t) ).
• Polar: p(t) = 3cos(3t), 3sin(2t) intvl=(0, 2π). Note: enter θ(t) and r(t) separated by a comma as above  the first component is θ(t)  (no enclosing parentheses around p(t)).
Points:
• 1,2; 2,3; 4,5; Note: enter the point (x,y) as x,y;
• Polar: 1,2; π,3; π/2,5; Note: The first component is θ; enter the point (θ,r) as θ,r;
When you enter points, new labels appear on three buttons as P(x), L(x) and CNCT. Pressing each will find and graph the polynomial of the least degree passing through all the given points, the line that fits best according to the least squares criterion or connect the points, correspondingly.
When no interval is specified,:
• The graphing calculator automatically appends a default interval to the function and parametric expression and draws the graph on that interval.
Graph MULTIPLE expressions on the same coordinate system:
• First long press 'Graph'.
When viewing the Graphs:
• Touch Polar on the upper right corner of the graphing area to draw the graphs in polar coordinate system.
• Drag the graphs. To center the graph on the screen, touch the coordinate indicator on the top left corner of the graphing area.
• Touch ++ or  on the lower right corner of the graphing area to zoom in or out.
• Touch the lower left corner of the graphing area (where the caption is) to reset zoom.
You can use the following in your expressions
• Basic algebraic operations
• Trigonometric functions and their inverses
• Hyperbolic functions and their inverses
• Exponential and logarithmic functions
• The Gamma function Γ (related to factorial) and Psi function Ψ.
• Absolute value and Step functions.
If your expression is incomplete or if you make a syntax error the = sign changes to ? mark. When you touch it, this artificial intelligent graphing calculator gives you a feedback by precisely indicating the error.
Other features
• Calculate complex numbers. Example: (2+3i)^i+5∠(4). You can use i or j for the imaginary unit.
• Calculate derivatives (symbolic) of functions and parametric curves and graph them.
• Solve f(x) = 0 to find all the xintercepts (zeros or roots of a function) on an interval without guesswork.
• Generate table of values for functions and parametric curves.
• Calculate definite integral, area and arc length.
• RAD and DEG mode.
• Scientific, engineering and fixed point notations.
• Units Converter  convert units of length, mass, time,... .
• Change background color of the calculator.
On this graphing calculator most keys are assigned a second functionality by long pressing. For example
• Long press of the backspace button x←: Clears the input box. Immediately after pressing it will display back the deleted expression.
• Long press of ^ (power) sign: Appends 'intvl=(' to the expression if it is not already there. Long press of decimal point inserts comma to separate the endpoints.
All of the above with more details are included in the builtin Instruction accompanying this graphing calculator.

Listen Read Device Only Added Installed Get Graphoid  the graphing scientific calculator with fast and easy zoom. Use the scientific calculator lookalike touch keyboard to enter expressions and functions, all on one screen without "2nd" key. Draw graphs or value tables, zoom in the values of the value table or graph by just touching the screen. Calculate min, max, intersections and more in graph mode as well as in table mode!
* EASY TO ZOOM GRAPHS OF FUNCTIONS
Use pinch zoom (twofinger zoom) to zoom graphs on multitouch devices. On older devices you can use onefinger zoom. Just long press the graphs to enter the zoom mode. Then just drag left/right/up/down to zoom. The scale grid is automatically updated. To select the interesting parts of the graphs has never been easier! With Graphoid calculator you can focus on inspecting graphs of functions, not how to use menus.
* ZOOMABLE VALUE TABLE OF FUNCTIONS
The functions can be investigated by a value table as well. By dragging the table up/down you move the visible interval of the function. You can even zoom the table values with pinch zoom on multitouch devices or by using the zoom buttons on the screen on nonmultitouch devices. The differences between the xvalues are auto calculated to be human readable. Rotate the device to portrait format and compare two functions in the table. Of course you can calculate min, max, intersections etc right from the table screen. To inspect functions with a value table is faster, easier and more intuitive than ever with Graphoid!
* SYNTAX HIGHLIGHTING INCREASES READABILITY
When you enter expressions or functions they are displayed with colored text; the negative sign has a different color than the subtraction sign, the scientific notation 'E' is highlighted by color so you don't miss it (we all have received answers like 1.394735386937635E9 without notice the 'E'). During the input of an expression matching parentheses are highlighted with color to make multi parentheses input more readable.
* EASY HUMAN READABLE ERROR MESSAGES
In case you enter an illegal expression you will get an easytoread error message. Also, if a calculation error occur a specific humanfriendly error message will tell you what went wrong; 'Division by zero', 'Log of a negative number is illegal' etc. Graphoid is made to help us avoid mistakes!
* STORED VARIABLES AND EXPRESSIONS
You can easily store variables with an arbitrary name and use them in future calculations. The last entered expressions are automatically stored and can be reused or edited.
