Time management is a big issue for contemporary students, and I learnt about their needs in this area by interviewing five students, and I organized the problems and needs into two categories: e-entertainment use restriction and study motivation.
Hamster timer/Home page/Store/To-do list
Statistic/Music choosing/Group work timer/Sleeping time record
Community/Entertainment(Little game)
I chose to make a timer with a lot of other different features, the options below include home page/timer, store, community, and statistic. on the way to using it, if the phone is switched to another software, the hamster stops running even if it also stops, something that helps the student to better focus on their learning without being distracted by mobile phone entertainment. And the reward system is also a motivation, the longer you study the more gold coins you get, you can buy more food or better running wheels, another motivation is that you can use it with your friends, this way you will want to work harder when you see others are still working hard.
