Park France — car parks near the destination with estimated prices

01

Overview

A native Android parking assistant for France built only on public data: national and city open-data feeds for car parks, street parking, tariffs, live occupancy and EV chargers.

02

Our solution

Kotlin and Jetpack Compose with a tariff engine that handles increments, caps, midnight and daylight-saving edge cases, MapLibre maps, and strict honest-data rules: an unknown price is never shown as free, and frozen feeds are hidden.
