This app is great for scholars and parents wishing to understand graphs in mathematics. While there are many graphing calculators that allow you to graph many complex functions, this one focuses on teaching simple grade 10 math graphs in a really simple and visual way. Using sliders to change the values of variables, you can see the impact the variable has on the overall equation or function, as well as other interesting things like x and y intercepts and asymptotes. You will quickly grasp just how simple graphs are by watching them change shape and move around as the value of a variable becomes larger or smaller or goes from positive to negative, or zero. Even parents will wish they had this app when they went to school, as they too will grasp just how easy and fun math is.

Specifically, the following graphs are included:
1. Lines of the form y = mx+c or ax+b
2. Parabolas of the form y = ax^2+bx+c
3. Hyperbolas of the form y = a/(x+b)+c
4. Exponentials of the form y = ab^x+c
5. Trigonometric function (sin, cos, and tan) of the form y = a*sin(bx)+c or a*cos(bx)+c or a*tan(bx)+c

You can also pan around the graphs and pinch to zoom in and out, and just tap the graph to reset the pan and zoom.

Enjoy learning math graphs, and drop me an email if you would like me to include a couple of other graphs that you or or children are struggling with.

Speedometers is a really simple and beautiful speedometer for your truck, car, motorbike, or bicycle. It uses GPS on your iPhone or iPad to establish your speed, and shows this information graphically in a simple user interface. You can change the units from miles per hour to kilometres per hour and back, and change the top speed of the speedometer reading. You can also let your speed guide what the top speed shown should be.

This is an easy to use financial calculator with three different tabs, all slightly differently configured. There are no number buttons or settings. You simply drag a bunch of sliders around, and watch as your monthly instalment for car finance or home loans gets recalculated, as well as the graphs demonstrating the payment down of capital and total interest. The retirement calculator allows you flex many different parameters relating to savings towards retirement, including your current age and the age at which you plan to retire, as well as your real salary increases and real investment return. You can see how these and other parameters like your current savings, will affect how much you have at retirement as a multiple of your salary at retirement. You can also see a full payment or savings schedule, and each calculator has its own help / info screen. The app also includes force touch from the home screen, as well as for peeks and pops from within the app, utilising the latest iPhone and iPad features.

This application is a digital scoreboard for your game of cricket darts. In cricket darts, two players compete to close the numbers from 20 to 10, and the Double, Triple and Bull (DTB) first. After scoring three hits on a number or DTB, the player opens that number or DTB for additional score until the other player closes it. The first player to close all numbers and DTB, and have the higher score, wins! It’s as simple as that.

The game provides a timer for additional information purposes only, as well as a count of how many turns have been taken.

What’s New

Thank you for the overwhelming support!

In this version:
I’ve added an undo button.
You can now enter the players’ names.
I’ve added a button to record misses.
I’ve added a button to upload your game to iCloud.
You can now see all your previous games, including the time taken, the date and time of the games, the number of turns and misses for each player, as well as the address (location) of the game. All stored privately in your iCloud account where no one else can see.

When last did you do, or see, or hear, or smell, or think, or feel something very specific? If you don’t recall because it has been a while, or you don’t recall because it happens so often, then this application is about to make your life a whole lot more interesting!

WhenLast? is a fun yet powerful application that keeps a record of every time something important or interesting happens to you or to those you care about, or to the world around you. Whether it is something that you have done, or a way you have felt. Whether it relates to activities or it relates to your health. Whether it happens all the time, or too infrequently to remember.

With one quick tap on the screen, you can record an incident for ever, and it will be accessible across all your devices as it is privately and securely stored in iCloud, where no one else can see.

You can add past events, and view statistics on the frequency with which all your events occur. This could be important if the events are medical related, or simply because you are either trying to do something often (habit forming), or trying to stop doing something (breaking a bad habit). The applications are endless.

To get you started, I’ve included about fifty sample questions across five categories (health, emotions, tasks, activities, and emoticons). Emoticons provide a beautifully simple representation of events of interest (see the sample screenshots). I’ve also allowed you to select your own background color for the application, so that it can match your favorite color, your mood, or your iPhone or iPad.

I’ve also added an “easter egg” for you to discover!

Please enjoy and drop me an email if you would like me to add specific colors, or simply tell me about other uses that you have found for the app!
