What I’ve made.

Every one of these started from something that caught my attention in ordinary life. Available apps and work in progress are kept apart so you can explore each world, then open its brand site.

Visited places

Colorvia

Colour the places you’ve been. Watch the map fill in.

Where it started
Travel records piled up, but how far I had actually been existed only in my head. I wanted a form I could take in at a glance.

A visited-places app focused on colouring countries, states, and prefectures. The map is the experience.

What it does

Colour a world map by marking the countries you have visited
Record sub-national regions where they are supported
See statistics such as how many countries you have visited
Place search, plus theme and map colour options
Export and import your records as JSON

Space & pause

Yohaku

Make space between your plans.

Where it started
I kept trying to make good use of time that had nothing in it. To leave it open, the emptiness itself had to be written down as a plan.

An app that makes small pockets of rest in a busy day.

What it does

Give unplanned time a name, a start and an end
Look back through Today, Week and Month
A quiet notice three to seven minutes before a space begins
One small check-in afterward that you can simply dismiss
System, light or dark appearance
