Ankarina

Product previews shown in German, the studio's working language.

Independent studio. Apps · Print · Writing · Music. Based in Germany. EU-hosted.

A studio for the things that take time to make properly.

Here the work runs across iOS applications for regulated spaces, illustrated editions, music, writing and independent projects. Few at once, made carefully.

Studio still life: open notebook with a lavender ribbon, a small cup of tea, a stack of books, a vinyl record at the edge, warm daylight across old oak.
