Test games and apps on your device by broadcasting them from the AppGameKit IDE on Windows, Mac, or Linux before using them in a standalone application. You can make games and apps in the IDE using AppGameKit's BASIC inspired script and at the press of a button see them running on your iOS device. Scripts can be used to write anything from simple applications to sophisticated 3D games. When you are happy with your script you can use the IDE to build it into a standalone application and use Transporter to submit it to the App Store*. Compatible with both AppGameKit Classic and AppGameKit Studio *requires a Mac

About

Uncertainty Calculator

This app allows users to perform error propagation calculations for mathematical expressions involving uncertain variables. It supports absolute and relative error inputs, various functions, and trigonometric calculations in degrees or radians. The tool helps ensure accurate reporting of results based on estimated errors.

Highlights
  • Error propagation calculations
  • Absolute and relative error input
  • Support for mathematical functions
  • Trigonometric calculations (degrees/radians)
  • Variable combination in expressions
  • Significant figure guidance

Read full description

Uncertainty Calculator evaluates the error propagation throughout the mathematical expressions comprised of variables of uncertain value. The application allows input of up to three value-error pairs (A, B and C), that can be used as a parameters in the final expression. Error values should be provided in absolute (100 +/- 5) or in relative format, the latter should appear in percent format (100 +/- 5%). The evaluated expression can include numerous functions, that provided by row of the appropriate buttons. Components and functions can be added directly to the expression field by pressing the corresponding buttons. To encompass expression into the preset formula, select the expression and press the corresponding formula button. Particular attention should be paid to placing brackets to avoid equation ambiguity. The application deals with independent, random errors. So if this is a case never use A + A, but rather 2*A and never A*A*A but rather A^3! Obviously, different parameters can be combined in any way (A+B or C *A^2 .. is perfectly fine). Angles for trigonometric functions can be provided in degrees or radians, and that should be reflected by setting a yellow button to "DEG" or "RAD". Bear in mind the importance of units in any of calculations! Implementation Examples: 1.The charge passing through an electrical circuit is defined by: Q = I * t, where I is the current and t is the time. Calculate the total charge value when a current of 0.15 ± 0.01 A passes through the circuit for 120 ± 1 s: Input: A = 0.15 ± 0.01, B = 120 ± 1 The final expression will be A*B, and press Calculate: The final value will be: 18 ± 1.2 Thus, it can be reported the total charge as 18 C ± 1 C. Important! One should only report as many significant figures as are consistent with estimated error! So the value should be rounded to the rightmost decimal place at which error applies. 2. A ball is tossed straight up into the air with initial speed vo = (4.0± 0.2) m/s. After a time t = (0.60 ± 10%) s, the height of the ball is h = vo*t - 0.5gt^2 = 0.636 m (g = 9.80 m/s^2). What is the value and uncertainty of height? Input: A = vo = 4.0 ± 0.2, and B = t = 0.60 ± 10%, then the final expression should be: A*B – 0.5*9.8*B^2 The final value will be: 0.6 ± 0.4 (meters).

Verdict

The call

The clearest difference is price: AppGameKit Player at Free against Uncertainty Calculator's $3.99. AppGameKit Player also leads on ratings volume (10 vs 1) and iOS requirement (9.0 vs 17.0). Uncertainty Calculator's advantage is rating (5.0 vs 4.0) and ads (none vs shown). On update cadence, in-app purchases and device support there is nothing between them.

AppGameKit Player is free to download; Uncertainty Calculator costs $3.99 up front. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

Uncertainty Calculator holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: AppGameKit Player has 10 ratings behind it against 1, so its average is the more settled of the two.

UpkeepUpdate frequency

AppGameKit Player ships an update every 2 months, Uncertainty Calculator every 3 months. The most recent releases landed on November 6, 2026 and November 2, 2026 respectively.
