Gboard for iOS is getting an update today that adds a significant new feature.
The Gboard for iOS update to version 1.40 adds haptic feedback, which you can enable by launching the app, going into "Keyboard settings", and then selecting "Enable haptic feedback on key press". When enabled, you'll get a small vibration whenever you tap a key to let you know that your press was registered.
Apple's default iOS keyboard doesn't have haptic feedback, so this addition to Google's Gboard is welcome. Since you're just tapping on glass, it can be nice to get a small vibration with each key press so that you know for sure your taps are being recognized. The feature is available on the iPhone 7 and later, so if you use Gboard, go grab this update and give haptic feedback a try.
The update to Gboard for iOS version 1.4 also brings language support for Lao and Mongolian and optimizations to Gboard assets that help to reduce the app's size.
