Native iOS features, added to your React Native app.

A countdown, a delivery, a match score that stays on the Lock Screen and in the Dynamic Island without anyone reopening the app. Three layouts to get right — compact, minimal, expanded — and update budgets Apple enforces quietly.

Shipped in Ticket, a parking timer, and in Qindil for prayer times.

Actions your app exposes to the system: a Siri phrase, a Shortcuts block, a Control Center button that works without unlocking the phone. Since WWDC 2026 this is the only route — SiriKit is deprecated, and apps still using it are invisible to the new Siri.

Ticket starts a parking session from Siri, from an NFC tag, or from the Control Center.

The widget itself is straightforward. The part that breaks is data: an App Group, a shared store, and a refresh policy that decides when iOS actually redraws it. Most widgets that show stale data fail here.

Widgets in Pilou, Amiens and Qindil, each reading data the React Native side writes.

React Native does not run on watchOS. The watch app is SwiftUI, full stop. What can be shared is the model and the logic; what has to be written twice is the interface. Worth knowing before anyone promises otherwise.

Watch apps in Qindil and in Amiens · Bus & Vélam.

A real domain model, not a bag of key-value pairs: relationships, migrations, and queries that stay fast as the data grows. On device, with no server and no account.

Pilou holds the full vaccination schedule, weight history and observations for each animal.

Not a cache bolted on afterwards, but a decision taken before the first screen: what ships inside the binary, what syncs, and what the app shows when it has nothing.

Isogonic makes no network call, ever. Amiens embeds the full timetable.
