Cadence

Cadence is a Flutter app designed for the cases that mainstream map apps treat as edge cases: planning a weekend hike, sharing live location with family on a road trip, finding the nearest specialist clinic while abroad, or tracing a route that mixes paved roads and trails. Routes save offline, location shares expire automatically, and groups stay private by default.

The Solution: Maps That Belong to You

The mainstream map apps optimize for two scenarios — driving and search advertising. Cadence optimizes for the rest: planning, sharing, and tracking in a way that respects user privacy and works without permanent connectivity. Live location sharing is opt-in per group, has an expiration timer baked into the UI, and the underlying tiles are downloaded for offline use before you lose signal.

The mobile app talks to an independent maps.onlainez.net API instead of being tethered to a single provider. That API is reusable: Klinio queries it for "find a doctor near you", Tisko uses it to compute delivery radius, and Orbit consumes it for live family location sharing. Built once, consumed everywhere.

What We Did: Native Performance with a Single Codebase

The mobile client is Flutter, which lets us ship native iOS and Android performance from a single Dart codebase while keeping native plugins for the parts that matter — background location, push notifications, secure storage of session tokens. The API is the first real consumer of the Onlainez-fwk Bearer authentication layer with refresh rotation and reuse detection, which means the same auth pipeline a web tenant uses also secures the mobile client.

Map tiles, routing, and geocoding go through a self-hosted stack so we are not metered or rate-limited by a third-party SLA. The API is versioned, documented, and treated as a first-class product rather than a hidden internal endpoint.

The Result: A Maps Layer the Whole Platform Reuses

Cadence is both a useful mobile app and a building block other Onlainez verticals plug into. When a Klinio patient needs to find a clinic with a free slot in the next hour, that query lands on the same maps API that powers route planning in the mobile app. When a Tisko customer asks if the restaurant delivers to their address, the radius check goes through the same endpoint. Building Cadence paid for itself twice: as a standalone product and as a shared infrastructure tier under everything else.
