Seven of the nine apps are not published — they were built as showcases. It says so here, because otherwise someone else would have to find out.



Vantis
Health & readiness
Seventeen screens that together explain a day.
Sleep, recovery, strain, goals — every number hangs on another. The largest app here, and the one that shows whether density can still stay readable.
17 screens · showcase



ProofFlow
B2B · job documentation
From job to signed record — without paper.
The job belongs to a customer, the documentation to the job, the signature to the record. What comes out is a real PDF — and that it survives a device restart is tested on every change.

VOLT SNAKE NEO
Game
Where design has nowhere to hide.
A game that feels bad is a bad game. The identity holds from the title screen down to the least remarkable settings row — that is the real test, not the first frame.
