I think my favorite “looking glass” app icon for now is Flow, the pomodoro app. The specular effect on it fits just perfectly IMO. Love it!

Deep linking always felt like some kind of rocket science 🚀 (“how is this even supposed to work?!”)…
But this week? We’ve cracked it — and I’m super proud 😄

With the job situation still going on, I’m struggling to be confident on myself. But those numbers are starting to look really great for a one guy project, right? These are the database entries per country and city on @koteiapp.bsky.social ☺️

As designer, I’m never really satisfied when working on a logo for myself, always find something to change or a good reason for starting from scratch… So… this is the new logo for @koteiapp.bsky.social 🤓
…and also the new website: kotei.app
