Most of us have heard of Google’s well-publicised moonshots: Self-driving cars, smart contact lenses, internet-beaming balloons, and more.
While those products and services sound amazing, most of us can’t use them just yet. But the company actually has a bunch of other ones that are incredibly useful that you might not even know existed. For example: Did you know Google has a massive free library of fonts?

Here are some of the under-the-radar services Google offers.

Android: Widgets are one of Android's most unique, flexible features. They can clutter your home screen if you have too many, though. Quidgets lets you tuck them away in your Quick Settings shade instead.

Android: Widgets are still one of the most useful parts of Android, but who has the time to go alll the way to their home screen to see them? Snap puts them in your notification shade, so they're always accessible.

iOS: Workflow is an incredibly powerful app for iOS that allows you to create your own miniature extensions to make working with multiple apps easy on iOS. Today, it gets an update that adds a new Today Widget so you can run those workflows without ever unlocking your device.

iOS: Want to covertly check in on Instagram without opening the app? Feeday stuffs your Instagram feed right into your Notification Center.

iPhone: Converting between timezones can be tricky sometimes. If you're looking for a simple way to glance at the time across the world, Klok is a Notification Center widget that does just that.

iPhone: Google has updated Chrome for iOS with a few handy new features. It now includes a pull-to-refresh gesture, a way to search from the Notification Center, and new suggested answers in the address search bar.

iOS: We really liked Launcher when it first came out, but it was pulled from the App Store within a few hours of its release. Now, it's back in the App Store to add all kinds of useful shortcuts to your Notification Center.

iOS: Music Center is a widget for iOS 8 that lets you browse your entire music library from the Notification Center. Once it's enabled, you can start playing music without having to open and browse through the Music app.

iOS: iOS 8's new widgets are a great way to make Notification Center more useful. Vidgets is an app that allows you to add information such as world clocks, device status and GPS information to your Notification Center.

iOS 8: Widgets in the notification center are one of the coolest new features in iOS 8. Paste+ is a good example of how that feature can be used: it provides shortcuts for your clipboard.

While Apple added lots of stuff in iOS 8, some of the best additions are Share Sheets, Safari Extensions, photo-editing extensions and widgets. Finally, we can now customise iOS just a little bit more. Here are some of the best we've seen so far.

Android: Widgets can make your Android phone or tablet much more productive. Month is a new calendar widget that does what most apps do, without ever having to open an app -- and it looks good too.

Android: Hop in your wayback machine. Google has updated its already-sweet News and Weather widget and released it to the Play Store. Yes, the one that was last seen with the Galaxy Nexus.

Android: Widgets are one of Android's best unique features. The trouble is they're limited to the home screen. Flippr solves the problem by putting any widget a swipe away.

Mac (10.9+): If you're looking to customise your desktop in OS X, usually you'd turn to an app like GeekTool. Now there's an alternative -- Übersicht, a new app that lets you build custom widgets to embed on your desktop and display whatever you like -- weather, to-dos, appointments.

Android: You probably have a handful of contacts that you call more often than the others, and usually at predictable times. CallWho learns who you call and when, then adds those contacts to a handy widget.

Your TV, Blu-ray player and DVR all come with remote controls, but if you use a PC to run your media centre, nothing comes in the box. Fortunately, if you have an Android phone, you can control just about everything on your PC.

Android: We love our widgets, but Google has yet to provide one for its messaging centrepiece app, Hangouts. Fortunately, a third-party app is on the case.
