Expo Go

What it is

Expo Go is a tool from Expo Project, filed under Libraries & Demo. It is free, rated Everyone, and first appeared on Google Play on December 8, 2015. The latest update in the data is October 19, 2026.

It is not a consumer app. The listing describes it as a developer tool for building experiences with JavaScript and React Native, using an Android device together with a computer. The store summary adds that Expo is a free and open source platform.

What it does well

The numbers are modest compared with consumer giants, but healthy for a niche tool. The app has 5,000,000+ installs and 32,021 ratings, averaging 4.31. Of those ratings, 76.7 percent are five stars and 4.6 percent are four stars.

The description is brief about features. It names camera, background location, audio and video, and SQLite as examples of what you can work with. That tells a developer the app exposes common device capabilities for testing.

The workflow is the real draw. The listing says you can start building with just your phone and your computer. For a developer who wants to see a project running on a real device, that is a clear promise, although the page gives no steps and we have not tested it.

Where it falls short

This is not for beginners. The description says some programming experience is recommended, and it directs you to expo.dev to learn more. If you are not a developer, there is little reason to install it.

The rating curve has a sharper bottom end than the average suggests. 11.9 percent of ratings are one star and 3.2 percent are two, so about one in seven raters scored it low. With only 32,021 ratings, a few thousand unhappy users make that visible. The data does not say what went wrong for them.

The listing is also silent on important practical details. It does not mention version compatibility, which projects can run, or any limits on what the app can do compared with a standalone build. The terms of service apply from the moment you download and run it.

Who it suits

React Native developers who want a quick way to see their work on a handset. Everyone else can skip it.
