Background Jobs — Periodic and one-shot background tasks that survive app restarts, with platform-aware scheduling and battery optimization.

HTTP Transfers — Resumable background file uploads and downloads with progress monitoring, Azure Blob Storage support, and foreground service integration.

Local Notifications — Rich local notifications with channels, scheduling triggers, and platform-specific customization.

Push Notifications — Native, Firebase, and Azure Notification Hub push providers with a unified delegate model.

SpeedyDock is an essential application for drystack marinas, boat clubs, and their clientele, streamlining the process of scheduling and monitoring boat launch requests, reservations, and additional services. It offers a user-friendly alternative to the frequent calls customers used to make, enabling electronic scheduling around the clock. Since its initial release in 2016, SpeedyDock has been accessible across iOS, Android, and web platforms, seamlessly integrating Xamarin and Shiny to manage native functionalities.

A core component of SpeedyDock’s efficiency is Shiny. It powers the app’s capability to work with permissions requests, local notifications, geofencing, and Firebase push, ensuring customers are consistently informed about their request statuses. For marina operators, these timely notifications are instrumental in enhancing service quality when customers set foot on the premises. Shiny has expertly bridged the gap between iOS and Android, offering a structured way to organize and share code, which, in the absence of such a tool, would be intricate due to variances across platforms and different OS versions. It has streamlined our development process for new features and minimized the edge case bugs typically associated with varying Android versions.

Shiny isn’t just a tool for SpeedyDock; it’s a cornerstone of our mobile app development. Its integration has empowered us to deliver a top-tier app with a native experience. Looking ahead, we’re eager to continue our journey with Shiny, leveraging its capabilities for upcoming projects and refining the SpeedyDock experience. It has undeniably been a key factor in our app’s success story.

— Travis Wolfe, CEO SpeedyDock

PoolMath is the go-to pool care app for hundreds of thousands of pool owners, and Shiny has been a critical part of our stack from the beginning. Running on .NET MAUI across iOS & Android, Shiny handles the native plumbing that would take months to build and maintain on our own. It just works, and it works well.

Beyond PoolMath, I see Shiny’s impact across the entire .NET MAUI ecosystem every day in my role at Microsoft. Shiny fills real gaps in the platform — areas where developers would otherwise be writing fragile, platform-specific code. It’s become one of those libraries that the community leans on because it solves hard problems cleanly, and it’s been instrumental in making .NET MAUI a viable choice for production mobile apps that need serious native integration.

If you’re building a .NET MAUI app and you’re not using Shiny, you’re making your life harder than it needs to be.

— Jonathan Dick, CEO PoolMath & Principal Manager @ Microsoft .NET MAUI

At Moultrie, we build mobile apps that connect hunters and landowners to our cellular trail cameras, feeders, and land management tools. Our apps run on .NET MAUI and lean heavily on several Shiny libraries to deliver the kind of native experience our customers expect — reliable background operations, seamless device communication, and responsive notifications even when cellular connectivity is spotty.

Shiny has been instrumental to our product development. What would have been months of platform-specific work across iOS and Android gets reduced to clean, shared code that we can build on with confidence. The breadth of the library suite means we’re not stitching together a dozen different packages with different conventions — Shiny gives us a cohesive foundation that covers our needs and lets our team focus on the features that matter to our users.

For any team building production .NET MAUI apps that need to go beyond the basics, Shiny is the library suite you want in your toolbox.

— Tommy Baggett, Principal Software Architect, Moultrie
