I was browsing StackOverflow and saw some cool looking ASCII diagrams, thinking to myself "How can I make these easily on macOS?". So that's how the idea was born.
I then spent about 1.5yrs from the initial commit until v1 release. Unfortunately, the financials didn't work out, so I had to find a job eventually.
But I'm still maintaining the app and do have longer term plans when my job situation changes.
I was one of the co-creators of Clear and the developer who built the iOS app. It was co-created by me, Realmac and Impending. I had previously interned at Realmac and had been friends with the founder, Dan (they acquired another app of ours - EventBox, which later got rebranded as Socialite).
