One passport-style entry stamp drawn for each of 194 countries. They are the stamps you collect inside Driftlog, an iPhone travel app I make on my own. The poster below is free to republish.
Use it anywhere, including commercially, with or without credit, no permission needed. If you would like to credit it: Driftlog (driftlog-app.pages.dev). I would rather you post it than ask me first.
Driftlog is a travel app for iPhone: it notes the countries and cities you pass through in the background, and it can rebuild trips you took before you installed it by reading the location metadata in your own photo library. There is no account and no server, so the stamps are collected on your phone and nowhere else. The stamps above are exactly the artwork in the app.
I am Akira Takashima, an independent developer in Alberta, Canada. Driftlog is free to install, with one optional one-time purchase. Questions, or a version of the poster without the title block: shiori.sutudio@gmail.com.
Also useful: an honest comparison of apps that track countries you have visited, written by me, including the ones I would pick over mine.
