Stacked
Stacked is a clean, powerful, and fully free weightlifting app designed to help users of all levels gain muscle and strength efficiently. Developed by Come On Software, the app combines smart workout planning with intuitive tracking, enabling users to stay focused on their goals without distractions.
Unlike typical gym apps overloaded with features, Stacked delivers a streamlined user experience — clear interfaces, fast navigation, and all the core tools a lifter needs. From progressive overload to personal best tracking, every detail is tailored to real-world gym use.
Built from the ground up, Stacked reflects our deep understanding of the fitness domain and commitment to building performance-first applications. It’s simple where it should be, powerful where it matters — and completely free, with no upsells or locked features.
Whether you're new to lifting or chasing serious strength goals, Stacked provides the tools you need to train smarter, track progress, and stay consistent — every step of the way.
iOS development
Our iOS team crafted a sleek, fast-performing app using Swift, focused on delivering instant responsiveness and real-time workout tracking. The interface is optimized for in-gym usability: large tap targets, minimal distractions, and smooth navigation between sets, stats, and history.
Android development
Using Kotlin, we built a native Android experience tailored for performance and reliability across all major devices. Offline support, quick data entry, and a frictionless user flow make the Android version of Stacked ideal for on-the-go lifters.
Web development
While Stacked is mobile-first, our backend infrastructure enables seamless synchronization and data persistence. We built scalable APIs to handle workout history, performance metrics, and user preferences with high reliability and speed.
Swift
We use Swift to create clean, efficient iOS apps that are easy to maintain and fast to use. In Stacked, Swift enabled us to implement high-performance screens for tracking sets, reps, and weight with zero lag or UI clutter.
Kotlin
Our Android stack is powered by Kotlin, which allows for concise, maintainable, and modern code. It gives us the flexibility to handle real-time user input, smart defaults, and long-running in-app sessions — all essential for a lifting app.
Node
The backend of Stacked is powered by Node.js, supporting rapid API responses, secure data storage, and robust user management. Our services are designed for scale, ready to support a growing community of fitness-focused users.
