The studio

Small studio, same discipline everywhere.

Rime Hill Studios is one developer, Rick Conner, publishing under Rime Hill LLC. Twenty-five years of building production systems went into how these apps are made.

Native where it counts

The games are SwiftUI and SpriteKit with no cross-platform wrapper. Projects are generated from a YAML spec with XcodeGen so the Xcode project never drifts from the source tree.

Logic tested outside the simulator

Game rules and extraction logic live in packages with no UI dependency, so they run under a plain test command on any OS and in CI before a build ever reaches a device.

Privacy-first by default

The games have no accounts, no sign-ups, and no in-app purchases. Ads are non-personalized only, the advertising identifier is never requested, and progress stays on the device.

Built for bad signal

CrewHub360 Field is offline-first because the trades work in basements, crawl spaces, and rural routes. Everything a tech does in the field is queued locally and synced when the phone reconnects.

A real person answers support

Every app page lists a support address that reaches the developer directly. Device model, OS version, and a short description of what happened is all it takes to get a fix moving.

Made in West Virginia

Rime Hill LLC is a West Virginia company based in Mineral Wells. The same company runs CrewHub360 and the consulting practice at rickconner.com.
