This is the kind of thing you wish to have around you just when you need it most. When something breaks down, you immediately want to know if it is still covered by warranty. When you cannot be sure, you do the next best thing, which is to search through your stack of hardcopy warranty cards or purchase receipts. Unless these cards or receipts are filed properly, it will be a sequential search; not an easy task. Furthermore, it will be very frustrating to find an expired warranty after all the panic and effort spent to locate it. If you experienced this situation before, you will appreciate this Warranty application. Keep the important warranty data in an easily accessible device that can be powered up quickly. Waiting for the desktop computer to boot up is not ideal either. You can check instantly if any devices are still under warranty.

We all own typical items with warranty, for example, watch, personal computer, TV, household and kitchen appliances, Xbox 360. Different devices have different coverage periods, namely days, months or years, and even lifetime. Devices are grouped into categories which can be maintained by you. If you like, you may enter service centre details for easy reference when needed.

The application supports the following features:
- user-created categories
- configurable currency code/symbol
- moving of devices between categories
- one touch database reset
- listing of all devices or by category
- searching of devices, with partial keyword
- devices with expired warranty will be highlighted in red
- data can be exported as Comma Separated Values (.csv). This allows other applications, such as MS Excel, to import the values, as another form of data backup.

Remember, when things break down, you will appreciate this application. At other times, this application contains relevant expense information to help you make informed decisions for future purchases. For example, price comparisons, product depreciation assessment.

Toy Clock

This is NOT a clock application. It won't tell you the current time of the day. There is already an app included in your iPhone or iPod touch that does just that. Instead, this is an application to teach your child, or anyone for that matter, how to read a time shown on a clock.

A clock has two kinds of hand: an hour-hand and a minute-hand. In this application, the hour-hand is represented by the blue arrow, while the minute-hand is represented by the red arrow. You can adjust both arrows by touching and dragging them around the screen. As the arrows are dragged around, corresponding blue and red guides appear to help you see where they are being moved to. The red minute hand moves in discrete intervals of 1-minute, while the blue hour hand can move smoothly and continuously.

There are 2 ways to play and learn all about clocks and time:

Set the clock:
You will be given a time. Your objective is to move the hour and minute hands to show the clock displaying the time given. Once you have adjusted both hands, press the Answer button, at the top right corner, to check your solution.

Tell the time:
You will be a given a clock arrangement with both hands positioned in a certain way. Your objective is to tell the time shown by pressing one of the buttons displayed on the screen.

The exercises given above will let your child practise setting a clock and reading a time shown on a clock. Both 12 hour and 24 hour notations can be used. In addition, you can learn to express time as a phrase. In other words, besides the numerical expression like 10:15, time can also be expressed as a phrase like Quarter past 10.

A new Mixed mode of game play is now available. There is an option to simulate and learn the movement of the hands of a clock. This is useful to show and explain how they move in relation to each other.

Please also read the Instructions page for more details about the Threshold setting.

Here is a video demonstration of this application:

BasicMaths iPhone OS application

This is an application based on the drill-and-practice instructional strategy. Similar to memorization, such a strategy presents the tasks to be completed repetitively to build up the foundation skills for more meaningful learning in the future.

This application provides exercises covering basic mathematical skills like addition, subtraction, multiplication and division. The exercises are targeted for children under 12 years, with varying degrees of difficulty depending on their age.

Memory iPhone OS application

This is one of my first iPhone OS applications for the iPhone 3G and iPod touch devices. It is a Memory game. One of the ways to improve your memory is to regularly engage in activities focused on the sensory and short-term memory.

Sensory memory allows an individual to look at an object or item and thereafter remember what it looks like with just a brief moment of observation. Short-term memory goes longer, retention from a few seconds to possibly as long as a minute.

The main aim of this application it to help trigger and exercise your sensory and short-term memory capacities. Your objective is to identify, remember and match pairs of pictures. There are many different pictures included in this application to fully stimulate your memory. Reveal all the pictures in the smallest number of moves or in the shortest amount of time.

Go get it from

You can also view a video of this game in action at YouTube.

Kayaking to Pulau Ubin

I made another trip to Pulau Ubin last week, and I've attached a few photos. The picture below is my AE AF 10.5' kayak.

Additional photos of the journey there:

This is Chek Jawa at low tide. Looking at the barnacle-markings on the walkway, that is the high-tide level.
