Built with ApkPy¶
The showcase is a visual test of the library, not a set of static mockups. Each app below is an executable Python program that was opened in the Hot Previewer, tested through its primary action and navigation, and transpiled into native Android sources.
Lumen — personal finance¶

Money without visual noise
Lumen combines a high-contrast balance surface with restrained supporting color. The screen uses themed containers, a rich transaction list, Material actions, toast feedback and a four-destination bottom navigation.
- Global light theme and reusable color tokens
- Responsive action row and financial summary card
- Interactive rich list and bottom navigation
Onda — daily wellbeing¶

A dashboard that knows when to stay quiet
Onda uses a limited lime-and-coral palette to make readiness, recovery and the next useful action immediately legible. Flex containers keep paired metrics balanced at phone width.
- Custom dark theme with clear semantic color roles
- Flexible metric cards and compact schedule composition
- Button feedback and state-preserving tab navigation
Northline — travel companion¶

Every travel detail in the right place
Northline treats the boarding pass as the primary object and lets the itinerary recede behind it. Nested containers build the route, timeline and trip actions without a custom Android layout.
- Native-style top app bar and four-screen navigation
- Nested horizontal composition for flight information
- Action feedback and itinerary hierarchy
Afterglow — music discovery¶

An editorial listening surface
Afterglow pairs local artwork with a compact listening queue and warm, tactile actions. The image is packaged into Android resources while the same source renders immediately in the Previewer.
- Local image asset with cover fitting and rounded corners
- Composed feature card and track queue
- Interactive playback action and saved-library navigation
Validation snapshot¶
The current local review generated four Android projects with a total of sixteen screen Activities. Every generated XML file passed parsing, generated Java passed structural checks, and the main transpiler suite completed with 146 passing tests.
The runnable showcase sources are kept with the 1.1 release preparation so they can be reviewed before publication.
