    Let’s catch a glimpse of the latest inventions this year.

Parallels lets you use desktop apps on your phone

You'd think most applications would have created a mobile app by now — but many companies still use desktop apps exclusively. Now Parallels Access lets you access them on your smartphone. All you need to do is download the app, then connect Parallels' Applification™ to your computer, so you can access important files and other apps with a single click. You can easily use your apps in full-screen mode, using intuitive(直观的) touch controls to work faster than before.

Usually,Parallels Access is $19.99, but you can get it now for $9.99.

Take your lighting to the next level with this smart switch

You probably don’t spend a lot of time thinking about your home’s lighting, but it’s important: the way that you control your lighting affects the environment (and your electric bill).

This WiFi wall switch is controlled via a companion app on your smartphone, so you can control connected lights or ceiling fans from anywhere.

Usually, the Meross WiFi Wall Light Switch costs $45.99, but right now it’s on sale for $39.99 .

Shoot beautifully clear videos with this smartphone gimbal

If you're interested in shooting professional-quality videos and photos, you don't have to spend a fortune to take a beautifully composed shot: just use this Rigiet Smartphone Gimbal instead.

A gimbal is a support for your camera (in this case, your smartphone) that allows it to pivot（移动）, and automatically detect and adjust to the position that you want to film in. Unlike any other camera hardware you might own, this one comes with its own accompanying app.

Usually, this Rigiet Smartphone Gimbal is $269, but you can get it now for $109.99.
