After much excitement, we're absolutely stoked to announce that Clear for iPhone - our collaboration with Milen and Impending - is finally available!

Clear is a complete reinvention of how you interact with lists and tasks, and we think it's pretty amazing. We spent a huge amount of time working to make the app simple, elegant, useful and above all fun - and it's so great to finally be able to say that Clear is now available on the App Store for just 99¢.

We hope you'll enjoy using Clear as much as we do, and can't wait to bring you some updates to it soon.

We've been inundated with requests for more information about our forthcoming app, Clear. There's been hundreds of tweets, and hundreds of thousands of video views, so given the huge interest we thought it only fair to give you an update on when Clear will launch!

So, without further ado, we're super excited to announce: Clear will launch on Wednesday 15th February! We're humbled to see such interest in the app, and we hope that when it launches you'll love the app as much as we do. Until Wednesday!

Just the other day we released the 1.1 update to our hugely popular photo-processing app: Analog.

Along with some much requested new features, Analog 1.1 also includes a few brand new filters and borders. To say that we take our filters and borders seriously would be an understatement... we take them VERY seriously. There's no guess work or "what might look trendy" here. Instead, each has been painstakingly built to accurately recreate real film and camera techniques. Sometime we go to the other side of the world to get it right. Literally.

Last October I took a holiday to South Africa and took with me not only my digital camera, but an old film camera - loaded with a roll of Fuji Velvia 100.

Velvia 100 is a gorgeous film stock that looks fantastic cross-processed. The results are often super high contrast, with over-saturated washes of orange and purple. Here's a photo I snapped from the summit of Table Mountain looking down on parts of Cape Town through the mist below:

The combination of the Velvia film and my old toy camera had created an effect with buckets of soul. This just had to go in Analog! So after much tweaking and experimentation I created the 'Cape Town' filter for Analog. I could now apply this to the rest of my digital photos taken from the mountain. Roll over the following photo to see how it compares.

However, I was well aware that the cross-processed Velvia look, along with the distortions you get from a toy camera - can be a bit heavy for some photos. Well it just so happens that Analog version 1.1 also introduces an intensity slider to the app so that the effect can be toned down as and when you need it.

This isn't any old slider though. What's the point in including filters if you're just going to remove the end result sequentially? There's nothing dynamic about that. It's like saying that the original filter just isn't good enough.

So we decided to approach the intensity slider as if every point in the slider could be a filter in it's own right. Keith, Analog's code captain, designed a way for us to gracefully scale back different filter elements. In turn, we looked at hundreds of photos which we had based our filters on so that we could work out how a filter still retains it's 'feel' at lower levels.

The result is not only a new version of Analog with three beautiful new filters but a version in which there is the perfect vintage effect for almost any photo you throw at it. Enjoy!

This week at Macworld | iWorld we're previewing something new, something for the iPhone… Say hello to our new app, Clear.

Clear is designed to help you manage your life without adding clutter. It's a beautifully-designed, gesture-driven app that we've created to improve on pencil and notepad for flexibly keeping quick, simple todo lists. Clear will be available in February on the App Store.

In the meantime, be sure to follow @UseClear on Twitter - and enter your email address on the Clear webpage to be the first to know when Clear is available.

If you're at Macworld, be sure to drop by our booth - in the OS X Zone, booth 228 #30 - to see Clear in action.

Clear is designed and built by Realmac Software, Milen.me and Impending.

As announced earlier in the month, we're excited to be exhibiting at Macworld | iWorld, which kicks off later this week! Myself (Nik) and Luke will be flying to San Francisco to man the booth, and during the course of the show we've also got Isaiah from YourHead Software and Joe Workman joining us to talk all things RapidWeaver.

If you're going to be at Macworld | iWorld this week, be sure to stop by the booth to say hello: we're in the OS X Zone, booth 30, and we'll be giving some Realmac tees and button badges out throughout the show.

See you there!
