Writeaday is a fun, visual journaling Android app designed and developed in conjunction with legendary coder, Eddie Lee. This app was designed to be a dead-simple, blazingly fast daily note-taking/journaling tool for those looking to record and reflect upon their thoughts.


How do we harness the benefits of an analog clock, as well as the benefits of a digital experience, to create something neither of them can achieve separately?

Existing Designs (Physical)

Existing planners (such as the ones seen on the right) had captured my attention for their ability to visualize time, but it was clear that restrictions existed for both types of designs. The most prominent problem being that it would be impossible to notate an event that begins at 10AM and ends at 2PM, without breaking the event up between two clocks.

Existing Designs (Digital)

Looking at the digital side of things, both of these existing apps have attempted to address a similar problem, and have resorted to using 24-hour clocks. This allows users to see an event that begins in the AM and ends in the PM.

Unfortunately, nobody has ever used a 24-hour clock and I found both cases difficult to use, lacking the instant spatial cue afforded by a true analog clock.


Through the creation of a spiral clock that never ceases, the analog clock is given an additional dimension. This allows the AM and PM to stay continuous and allows users to visualize events throughout the day in a much more natural and intuitive manner.

As you swipe across the screen, the AM clock begins to unravel and display the PM clock behind it.


Once I had a clear grasp of the mental model of this new digital clock and how it operated, I needed to focus on how to represent this idea to users effectively. This included how a user would interact with the clock as well as communicating visually how it works. I started off experimenting with different ways of representing both AM and PM in one clock interface.

The two main interactions I focused on were the experience of creating an event and the experience of "unraveling" the clock to visualize one's whole day.

Ultimately, I settled on a very minimalistic style that brings attention to the events planned throughout the user's day. I wanted this app to do just one thing, and that one thing extremely well. Through its simple but powerful functions and intuitive interaction, I believe I've achieved this goal.
