One developer.
8PLAY STUDIO.
I'm Quyen Dang, an independent developer based in Lâm Đồng, Vietnam. I design, build and support the apps at 8PLAY STUDIO.
What I make
I build apps around specific parts of everyday life: a treadmill run, a classroom, the next bill or a focused work session. My portfolio spans health and fitness, education and personal productivity.
StreetStride brings real-world routes to indoor workouts. FastScores helps teachers organize their classrooms. FastRemind, FastFocus and FastLoop are tools for payments, focused work and daily routines. KneeClap and JackFit are my newer exercise-counting projects.

How I work
I handle product design, development and support myself. Claude Code is part of my development toolkit. When you contact the studio, your message reaches the person behind the apps.
