These last three weeks we have been working on apps for smart phones. I decided to make a cleaning app for three people living in a shared apartment, this based on my own experiences. The app was going to work like a relay (from a relay race). You get the “relay” when it is your turn, it reminds you when it is time to clean and when you are finished cleaning you have to check out that your have done your job and send it to the next person. This person then has to accept it, by this he/she is accepting that you have done your job and that he/she got the “relay” and know it is his/her turn to clean next week. This person then rates you on how well you have done your job so you get feedback on how you are doing your job. This are stored in a statistics part where you can see your own effort over time and compare with your room mates.
