You can set a sleep timer in the app so the music will stop automatically - that way you can focus on sleep. They have even created some new relaxing tracks (some even using binaural beats) to help you fall asleep faster and achieve even more restful sleep. 

ZEEQ links to a smartphone app, so you can see your sleep data, including your Snore Score. If you want to take it a step farther, the app can help you track your diet, exercise and other habits to analyze how these factors effect your sleep, so you can make changes toward more restful slumber.

1.  Discovery   -dream talk-

On this page users can explore dream talks, and upload their own dream talks.

Current design: The hierarchy of the information is not appropriate, the ‘Explore dream talk’ should be the priority information to the user.  ‘Snail Mail’ is an online store for snail smart pillow. ‘Online store’ is better remove from Discovery feature.

Redesign: Instead of click lots of buttons, 'filter' is easier for user to access.


2.  Discovery  -Healthy Sleep-

'Healthy Sleep' includes bedtime articles, stories, and night forums.

Current design: The hierarchy is disturbed by colors. Colors are too bright when users are reading at night.

Redesign: Articles organized by user’s interests with 'guess you like' feature. Also, Colors are being unified and darker


3.  Daily Report List

Current Design: The graphs are hard to read.

Redesign: The graphs are enlarged. Timeline and the sleep score are more readable with larger texts and graphs.


4. Daily Report  -Data Visualization-

Redesign: Colour transition make graphs more modern and eye-catching


5.  Weekly Report  -Data Visualization-

Current Design: Stacked bar chart can only read total sleep time and overall proportion of each category.

Redesign: Data is more clear on the radar chart. Colour transition make graphs more modern and eye-catching.



Overall, Snail Sleep is an excellent app with modern design and pleasing colours. Compare to other competitors on the market, Snail sleep has better design and unique features such as the dream talk community and bedtime articles. The app is also supporting multiple languages to users with different cultural backgrounds. However, the hierarchy of information could be improved.
