In today's day and age, smartphones are part and parcel of our everyday routines. We wake up to an alarms set on our phones, check news and weather apps while getting ready, stream music or podcasts on the way to the office, check what we missed on social media, and review emails — even when laptops or desktop computers are readily available. When it comes to writing lengthy emails or editing documents, however, many people finally put the smartphone down because typing on a tiny keyboard is time-consuming, inefficient, and pretty darn error prone. A simple fix? Pick up a Bluetooth keyboard.

There are many different types of smartphone-compatible keyboards, from extremely slim fold-up models to vintage-inspired typewriter designs with satisfying clicking keys. Whatever you’re looking for, you can increase your productivity and mobility easily by working (or playing) on your phone with a Bluetooth keyboard. Check out our list below for some of our favorite Bluetooth keyboards available from top online retailers.
