ChronoBook is an innovative day planner for iPad where you draw and plan your activities around the clock, combined with making notes, mindmap, sketches, and scribbles.

ChronoBook is a minimalist daily planner for iPad and Apple Pencil where each day is represented in AM and PM and you plan your activities around the clock, make notes, sketches, and scribbles. It's a day-planner, mind-map and scribbly notes all in one.

Typical day planners have lost the freedom to express yourself, by trying to define your life in small boxes, but life does not conform to boring lines of a grid on the typical day planner, our lives are not always contained in a grid. We will always have to write something outside the lines. There's never enough space for your life.

Enter ChronoBook: This day-planner bravely remove all the rigidity of a typical day-planner and start fresh with an idea.

It frees up clutter typical of daily planners, by embracing the analog notion of representing time by putting an analog clock in the middle of the page.

The clock occupies just a small amount of space, where you can plan your activities around the clock, make notes, sketches and scribbles. The rest is completely flexible.

Each page represents either AM or PM, and you write your plans like a dial of a clock, it is very easy, simple, but yet effective. Focus on the individual tasks of the day, rather than being forced to engage with every calendar day.

It's intuitively organized, it's the simplest clear definition of what a day planner is all about.

Like an analog clock, the relationship between projects and tasks gives you a sense of better control of the time, and easily visualize allotment of time and how relates in the day.

And there's something special about seeing your plans layered out in the wheel and how it relates to your day. It gives you a sense of better control of your time.
