Mo Calc “clone” detected

I was checking up on Mo Calc over at Windows Phone 7 marketplace today and I came across an interesting finance app.

It’s called Loanster. Check out these screenshots below:

Despite drawing inspiration from Mo Calc, I am assured that Loanster is a completly legit and independently written app. Its author Tony was nice enough and agreed to tweak the UI in the next version in order to differentiate Loanster from Mo Calc a bit more.

Mo Calc 1.2 released

I finally had some time to release a much-needed update to my free mortgage calculator for Window Phone 7. Mo Calc 1.2 sports a new payment summary page with pie charts to better visualize payments structure.

I also revamped the comparison page. I decided to hide the detailed numbers and only display the monthly and total payments, in order to fit more items on the screen. The details are still available – just click “show details” to expand them.

I felt that the amortization table was pretty useless in the previous version. Who wants to scroll through 360 months of rows to see just a bunch of numbers? My plan is to gradually start improving it and making it more user-friendly. Version 1.2 has a “quick jump” capability (alike the people hub in Windows Phone 7) allowing quick hop to a designated year. Click on the year header to activate it.

There were also other miscellaneous improvements that made it to this version. Here is the list:

Version 1.2

  • Improved payment summary page
  • Added pie charts
  • Improved amortization table
  • Using large numeric keyboard for number input
  • Added collapsible details for mortgage comparisons
  • Performance improvements and bug fixes
  • New icon and splash screen
  • New About page
Update: Looks like I made a simple “copy and paste” error and both charts are the same. Thank you TheManOfSteel27 for pointing that out. I already submitted an update to the Marketplace. Now just waiting for Microsoft to approve it.

 

Microsoft’s redemption

Yesterday Microsoft finally reactivated my App Hub account so I was able to publish a long overdue Mo Calc update. It did take them a whole week and I still don’t know what the issue was in the first place. I guess at this point I don’t really care. To sweeten the deal Microsoft reimbursed my money and pre-paid the $99 for a yearly App Hub membership. That, plus my app was approved after only a few hours. Call me satisfied.

Cool

First Windows Phone 7 App

As you undoubtedly heard from my posts on Twitter, I have published my very first Windows Phone 7 app. Yes, you guessed it right – it’s a mortgage calculator called Mo Calc.

Dev Experience

I wanted to see if Microsoft’s promise of reusing existing Silverlight code on the phone was true. Indeed it was, but mainly for the business logic. The unique space constrains of a phone screen pretty much required a brand new UI. I was glad my old code followed the MVVM pattern – I was able to quickly use databinding and get the new UI of the ground.

I really enjoyed styling the interface in Blend. Microsoft did an awesome job on this front. Visual design makes writing apps much quicker, even quicker than on Android. You don’t have to deploy to the device/emulator to see how your UI will look like.

The APIs feel fine as well – every .NET dev will be at home. That said, I must say I personally like the “intent” model of Android better that Silverlight’s web-like “navigation” model. But that’s just my personal opinion. I’m still giving WP7 dev experience very high marks.

Marketplace Experience

Unlink Apple, Microsoft has published clear guidelines of what is allowed and what is not. It was nice to be able to read a document outlining all the things that are considered during the certification process. I chose to make my Mo Calc free and make money from ads. Microsoft allows 5 free app submissions.
Publishing Mo Calc through the website was very easy; a typical “wizard” experience. I was told the approval may take as long as five days, but my app got into the market just after 18 hours. Nice!

The Bad and Ugly

While the quick submission turnaround time was certainly impressive, Microsoft managed to frustrate the heck out of me.

Right after my app made it to the market, I received a confirmation email stating that my marketplace account had been cancelled. Wait, what?
You read it right. The money was refunded to me, and I can no longer log in. Why did this happen? Nobody knows.

I have been calling MS tech support every day since, but was told that it may take more than a week to get my account reinstated. Very, very frustrating!

Meanwhile, my app is available in the marketplace. I have since found a few bugs and issues (ex. the ads are not showing, so I am not making any money) that I would like to fix, but I cannot access my account. Thanks Microsoft. I just hope that no one gives my app negative feedback for the glitches.

I’m really hoping my account gets reinstated soon…
