    I just wanted to say that I really like the new Metro icon for your app. It does however, look more like a Calendar than a calculator, but it's close enough. It's obviously inspired by the new Office Icons, which I also like. Great job!
    Thanks, I'm glad you like it! I'm working on the Windows 8 port and the old logo really didn't work there. I downloaded Office 2013, saw the new logos, and redesigned mine the next day.

    PS. I think the calendar logo looks more like a calculator. :P

    Calculator≤ app for Windows in the Windows Store

    The Windows 8 version of Calculator≤ is now in the Windows Store!

    It's still at an early stage and only features the Basic and Scientific modes, but I'm looking to have everything included by the time Windows 8 hits general release.

    I've made a few updates to the phone app to reflect the changes now already in the Windows 8 app. The update (version 1.15) is currently being certified and should be published early next week. The main changes are that I added an extra row of buttons (don't tell Apple!) to the Scientific Calculator as shown in the image above, providing a better balance between ease of access to commonly used functions and large button sizes. I've also removed the +/- buttons from each memory item. Numbers can now be added to or subtracted from (multiple) memory items using the +/- buttons in the app bar. Finally, there are a few minor visual changes, bug fixes and the odd performance improvement.

    I also want to say that I've decided to remove the background task for automatically updating the exchange rates and Currency live tile from the free version. This is now only available in the Pro version, and in Windows 8 will be available via the in-app purchase that currently removes the ads. The exchange rates are provided by the excellent service at Open Exchange Rates, an open source venture by Joss Crowcroft. Due to it's popularity he is now charging for the service to help keep it going. Similarly, due to the large number of downloads of Calculator≤ the background task is making a lot of requests for the exchange rates data, and I can no longer support this with the current monetisation model. This was my own decision in anticipation of increased success with the app in the coming months thanks to Windows 8 and Windows Phone 8, and not at all forced upon me by Joss. I simply do not want to abuse his service without being able to contribute fairly.

    Richard Walters.

    Does either calculator app support RPN?

    Hi Laura. They don't at the moment, but RPN is probably my most asked for feature so I've already decided to add this as a 2.0 update. I have some good ideas for the layout and how to implement the stack, so hopefully I can create quite a nice version. However, it's going to be a few weeks before I can get started on this; I'm finishing my phd thesis at the moment and then I want to get the Windows 8 version up to the same level as the phone version before general release. There's also the Windows Phone 8 SDK coming out soon which I'm eager to play with!

    If you have any specific requests for the RPN implementation please voice them in this thread. The feedback will be useful as I haven't got that much experience with RPN calculators.

    I'll second the request for RPN. I like the Calculator3 app so far, but RPN would make it wonderful.

    The best example of RPN is the HP-12C.

    My one major issue with the HP-12C is that you only see one line of the stack (at least from what I recall). That's why I've always liked the HP-48G. Then again, I'm an engineer, so my uses are probably different than most financial people.

    Though frankly, most of the time nowadays I simply use RPN to balance my checkbook, etc. So a basic calculator, with just the major basic functions (numbers, enter, +, -, /, x) with a visible stack of 3 or 4 would be awesome.
