Your to-dos on all your devices. Things Cloud is a free service that keeps your to-dos in Things updated across your Mac, iPhone, iPod touch and iPad.

It’s simple, fast, robust, invisible and secure.

Simple.

Turning it on is as easy as flicking a switch in the settings and creating a free Things Cloud account.

Once it's on, everything happens automatically. Every time you change something on one device, it is immediately sent to Things Cloud, which then sends it to all your other devices. You’ll never have to worry about syncing your to-dos again - Things Cloud does everything for you.

Fast.

When you're on the go, you want to quickly pull out your iPhone, enter a to-do, and put it away again. You shouldn't have to wait for this change to be sent to the server.

So we built Things Cloud to be fast - crazy fast. Compared to the previous Bonjour Sync, Things Cloud is up to 4x faster in common use cases.

How did we achieve this? It involves some beautiful engineering of how Things Cloud and Things store and update your to-dos. And this beauty is more than skin deep: We have completely rewritten the inner workings of the Mac and iOS versions to be highly optimized for Things Cloud. As an example, when you log 100 items to the Logbook, only a single piece of information needs to be sent to the cloud: the current time. This happens so fast you barely even see it happening.

Robust.

When your goal is to build a reliable cloud platform, you don't just ship your first working version. Things Cloud had its first internal test flight over a year before launch, and we’ve been iterating, improving and refining it ever since.

To date, hundreds of thousands of users have created a Things Cloud account, helping us make it the most robust and reliable system we could conceive. Here’s what they’re saying.

Invisible.

Did we mention that Things Cloud is simple? It’s so simple, in fact, that after turning it on, you’ll never see it again – unless you want to, of course.

Every time you change any of your to-dos, Things automatically triggers an update with Things Cloud. If you don't have an internet connection at the moment, but it becomes available shortly after - Things automatically triggers an update. Every time you switch applications - Things automatically triggers an update. See the pattern? All of this means that you never have to worry about or interact with Things Cloud directly. It just sits there, happily performing its duties. And, dare we say: it just works.

Secure.

It's nice to know that your data is safe when you're working in your local coffee shop, or riding on the train.

With Things Cloud, all your network traffic is securely encrypted using the latest SSL technology, ensuring that everything you do is for your eyes only.
