Sleep Cycle is an App I used for a long time and it is very useful for preventing restless sleep. Sleep Cycle uses sound analysis to identify sleep states by tracking movements in bed. It uses a wake up phase (30 minutes by default) that ends at your desired alarm time. During this phase Sleep Cycle will monitor signals from your body to wake you softly, when you are in the lightest possible sleep state.
For the UX aspect, it has a very clear data diagram to show the sleep quality of users.
It is very easy to use and the instruction is very clear and easily accessible.
In the game, player need too help a princess proceed on her mysterious quest, player will facing ingenious puzzles that involve lifting and spinning the environment. It uses different perspectives of the environment to create visual illusions for players. The graphic is very visually appealing. The game mechanism is not complex but it is very relaxing to play to me.
