My two favorite technologies are Mobile and Golang. It might sound like an unusual combination, but I completely disagree. There is a powerful tool called GoMobile that brings these worlds together.
GoMobile takes advantage of Go’s interoperability with native mobile languages. It allows you to consolidate business or performance-critical logic in one place. For applications that need native-level speed and cannot afford the memory overhead of something like React Native, GoMobile becomes a strong option. It is not a framework or a lightweight webserver, although you could build one with it. At its core, GoMobile lets you call into Go code just like you would with any other interoperable language.
Why not write this in C?
You absolutely could. But let’s be honest. Outside of a small slice of developers, most of us are not trying to spend long days inside C or C++. One of the reasons I advocate for Golang is because it hits a rare balance of developer friendliness and performance. GoMobile gives you these same benefits. You get native performance while keeping your core logic in a centralized, maintainable place.
Does it actually work?
It does. I am using GoMobile today for two production apps currently in the App Store, and I am finishing a third one. This third app is the most exciting because it really showcases the strengths of GoMobile. It processes audio streams using several operations, including a Fast Fourier Transform (FFT). It is a great example of how GoMobile can handle performance-heavy tasks without the complexity of writing them in lower-level languages.
If it is so great, why isn’t everyone using it?
Like any tool, GoMobile has trade-offs. Teams need to decide whether the benefits outweigh the effort for their specific application.
Downsides
Language requirements:
GoMobile requires Go. That should not surprise anyone, but it does mean your team is picking up another language. The learning curve is much lighter than C, so for many teams this is actually an advantage.
Limited type support:
You can only send primitives and byte slices between Go and the mobile layer. This can feel restrictive. I use Protocol Buffers to structure data, which adds a bit of complexity and computational overhead. It works well, but I know it is only a matter of time before I hit an edge case.
Additional benefits
Before getting into examples, there is one more benefit worth calling out. If your backend is also written in Go, GoMobile unlocks logic and data model sharing between your frontend and backend. For the right project, that can simplify maintenance and strengthen consistency across the entire application stack.
Example
This is from my first app built with GoMobile. It is intentionally simple, which made it a perfect starting point. The Go code maintains all the chemistry equations and the functions required to calculate the answers.
Here’s the protobuf file for the project:
This next section looks a little intense at first glance, but it becomes straightforward once broken down.
The result is used to populate a SwiftUI list view. From there, it is standard UI work.
The final interesting piece is the calculation screen. The main function is called calculateValue. It runs when the user taps the Calculate button. There is some boilerplate around the protobuf conversions, but that could be abstracted cleanly.
Final Thoughts
GoMobile will never be the most mainstream mobile solution, but it fills a meaningful and often overlooked space. It delivers native performance, centralized logic, and a straightforward developer experience without the weight of C or the overhead of hybrid frameworks. For teams already working in the Go ecosystem, it can be a game-changing bridge between backend and mobile.
At RBA, we see this as a strong example of the practical, high performance engineering patterns we bring to clients. For the right application, GoMobile is worth serious consideration.
