Google Go, a lightweight version of Google’s search app, is today becoming available to all Android users worldwide. First launched in 2017 after months of beta testing, the app had been designed primarily for use in emerging markets where people are often accessing the internet for the first time on unstable connections by way of low-end Android devices.

Like many of the “Lite” versions of apps built for emerging markets, Google Go takes up less space on phones — now at just over 7MB — and it includes offline features to aid those with slow and intermittent internet connections. The app’s search results are optimized to save up to 40% data, Google also claims.
