Watch it run

Filmed from the real app, beside its real code. All of this motion is in the zip.

Screens ripple out of the control you touch
The orb travels the dock and every notch follows
Amounts roll on digit wheels
The card deck rides a loop
A satellite carries each top-up to the goal

One folder per feature

Data, logic and screens stay together, so each feature is easy to find and change.

Demo data in one place

All sample content sits behind one repository, so you know exactly what to replace.

Motion you can tune

Every animation is a plain timeline, with the timing in one file.

Names over comments

No comments in the code. Longer guides live in the README.

What is in the zip

A full project that runs with one command. No backend, login or live data, so you connect your own.
