The best thing about Gboard is that it’s free. You are never asked to pay to unlock new features, and you never see ads on your keyboard to support the developers. You can also sync your dictionary to your Google account to personalize text correction. The pro version of Chrooma includes a grammar and spelling checker, which you launch by tapping the icon in the upper-right corner of the keyboard. From there, you can see the app’s suggestions. You also get access to a clipboard for copied text, and you can build your own custom themes. However, to get access to every feature available, you must pay for the pro version of the app. Pro features include typing speed analysis along with other stats and more theme options. The premium version includes a grammar checker that offers suggestions for improving sentence structure to make sure your messages sound professional. As a bonus, it includes free Android games that you can play in the app.
