Expo Go

Review by eFreeware

Expo Go is for people who already write code and want to see it running on a phone without a long setup. The developer describes it as a free, open source platform for building apps in JavaScript and React Native, and that is the audience it serves: programmers, students and hobbyists who are comfortable in a code editor and want their Android device to be part of the workflow.

What it gives them is a way to build interactive experiences using a phone and a computer together. The focus is on gestures and graphics rather than plain screens, so the apps you make here tend to be things you can touch, drag and watch move. If that description fits how you like to work, the rest of this review explains what the tool provides and what it expects from you.

A development environment in your pocket

The core idea is simple: you write your app with JavaScript and React Native, and Expo Go lets you run it on Android. The developer frames the whole thing as a platform for rich experiences, which in practice means apps built around movement and interaction rather than static text.

The tool is listed in the Libraries & Demo category, which is a fair signal of what it is. It is not a finished product you consume; it is scaffolding you build on. Anyone expecting a ready-made app to open and use will be disappointed, while anyone who wants a place to experiment will find the entry point fairly direct.

Because the work happens in code, the experience is shaped by whatever you bring to it. The developer notes that some programming experience is recommended, and that is worth taking at face value. This is a tool for people who already know their way around a project, not a tutorial that teaches you from zero.

Camera, location, audio and video

The features listed are the ones that make mobile development interesting. Camera access is listed, which points to apps that capture images or react to what the lens sees. Background location is also included, opening the door to projects that track movement or respond to where the device is.

Audio and video round out the media side, so experiences can play sound, record it, or work with moving pictures. These are the building blocks that separate a phone app from a web page, and having them available through the same JavaScript and React Native workflow is the main appeal of the platform.

I would expect these capabilities to matter most to people building prototypes, demos or small experiments. If you have an idea that depends on the camera or on location, this is the sort of environment where you can try it without assembling a stack of separate tools.

SQLite for data that sticks

SQLite is the fourth feature, and it is the quiet one. Camera, audio and location are visible; a database is what lets an app remember things between sessions. Including it suggests projects that store structured information.

For a developer, that combination is practical. You can build something that captures media, records where it happened, and keeps a record of it. Together these features cover a reasonable range of what a small app might need.

The emphasis on interactive gestures and graphics, meanwhile, is a hint about the kind of work the platform is designed around. It is not pitched as a tool for building forms and lists. It is pitched at experiences you touch and watch.

What it asks of you

The requirement stated most plainly is a computer alongside your Android device. The app pairs the device with a computer, which shapes how and where you would work on a project.

The second requirement is programming experience. The developer recommends some, and the whole premise of writing apps in JavaScript and React Native supports that. Someone with no coding background would be starting a long way from the first step.

On cost, there is little to weigh. Expo Go is free, carries no ads, offers no in-app purchases, and the platform is open source. Running it means agreeing to the terms of service published at expo.dev/terms, which is the usual arrangement for a developer tool of this sort.

An audience of builders

It suits students learning mobile development, independent developers prototyping an idea, and anyone who wants to test how a gesture-driven interface feels on a real device.

The install numbers back up that it has found an audience: more than 5 million installs and a 4.3 average from over 31,000 ratings. That is a healthy signal for a developer tool, though it says more about how many people have tried it than about how any individual project will go.

It has been available since December 2015 and was last updated in August 2026, so the project has a long history behind it. None of that changes who it is for. If you write code and want a phone in the loop, the pieces here line up with that goal.

A practical choice for React Native prototyping

Expo Go is worth installing if you already work in JavaScript or React Native and want to build and run interactive experiences on Android. The combination of camera, background location, audio, video and SQLite covers a lot of ground for a small project, and the fact that it is free, open source and free of ads or purchases removes most of the friction from trying it.

The trade-offs are clear: you need a computer as well as your phone, and you need some programming experience to get anywhere. Those are reasonable conditions for a development tool, but they do define the audience clearly.

For the right person, the appeal is direct. You get a long-established platform, a large install base and a focused set of mobile capabilities, all aimed at building rather than browsing. If that describes what you want to do, this is a sensible place to start.
