Everybody wants to be fashionable, but not many people have the time to go out and buy trendy clothes. Usually, you have to go to Central or Causeway Bay to try on a stylish outfit. Online shopping is a good alternative, but it's risky because you don't really know whether the clothes will fit you. If I could design a mobile app, users would be able to take a full body shot of themselves and use the photo to 'try on' different clothes. That way, you wouldn't have to worry about buying an outfit online because you'd know it would be 'perfect' for you.

My app would be called 'The Maths and Science Killer'. It would solve maths and science problems if you take a photo of the problems or read the questions out aloud. The phone would immediately analyse the photo or your voice and then answer the questions with a built-in memory. Within seconds, the answers would pop up on your phone, along with the steps, so you would understand how the answers were done. This cool app would also help you create graphs while tackling calculus or physics questions.

If I were to design a mobile app, it would be called 'Good Deed of the Day'. It would encourage the user to do a good deed every day, and the deed would be related to the users' job. For example, if the user was a teacher, the app would suggest: 'If a student misses the deadline for submitting homework, extend it.' If the user was an office worker, the app would say: 'Treat a co-worker to coffee.' This app would help boost morale and remind people to help others. Helping others would become a habit and the earth would be a better place.
