DualShot from the launch to 100 000 downloads in 20 days

My friend designer Vincent and I decided to share the story of our latest app DualShot. The goal is not to be show-off. We want to show diverse statistics that can help analyze the Windows Phone market and encourage other developers and designers to continue providing quality apps.

Before starting, DualShot has two restrictions:

  • It is only available to Windows Phone 8 devices.
  • It requires a back and front face camera. In other words, the most popular devices the Nokia Lumia 520 and 521 cannot download the app, because they don’t have a front face camera.


The launch date was September 16th. The download count surpassed 100 000 on October 15th.

It’s not a big surprise that the peak arrived close to the launch date. DualShot received a lot of good press from many Windows Phone websites.

Here is the top 30 markets. We were quite surprised that India and Thailand arrived on the second and third spot despite the fact that DualShot was available in English and French only at launch. The two biggest continents with the most users are Europe and Asia.


Complete list

Here is the percentage usage per device. There is no doubt that Nokia is dominating the Windows Phone market. The non-Nokia device with the biggest market share is HTC with 5.3%. Looking forward, I’ll be curious to see how the Lumia 1020/925 will evolve. Their percentages are low because they are new and not available worldwide yet.

Concerning the reviews, there is a clear relation between the number of reviews and the downloads. The American were the most critics about our app!

Developing an app is one step, but advertise an app is another step. I’m not a firm believer that submitting an app without talking about it that the app will become popular.

The day before the app went live, we contacted a lot of editors and friends. A full day can be easily spent sending all the information.

For those who noticed, we created a little teaser on September 26th. It turned out that the one-day teaser worked well.




At this point, this is where the team has less control. It is the turn to the public to decide about the success of the app. It is also on the hands of the editors if they want to talk or not about the app. This is the most exciting and stressful period where the team awaits the result.

In the case of DualShot, we were very happy with the first days following the launch. In reality, it surpassed our expectations.

We were proud to appear twice on Windows Phone Central:

We were delight to see a YouTube review from our friends at WinSource:

We had a review on a Microsoft Canadian website and many more sites.


Having a lot of tractions at launch caused a positive domino effect. The more an app is downloaded, the more it appears on different categories. At some point DualShot was the top New+Rising app in USA.


A week later, the download count probably caused a trigger on the algorithm of Microsoft to display the spotlights. With the help of my app App Spotlights, I was able to detect that DualShot was on the spotlight of many markets on October 4th.


Later on, we had one occasion with the big spot in the USA spotlight page. We can see the effect on the graphic at the top of the blog post.


So far, we had a lot of exposures:



While we didn’t make any money from releasing DualShot because we made it free, we had so much fun following the launch. It surely motivates us to create more Windows Phone apps. Now that the Windows Phone market is not small anymore, we see a lot of opportunities and we encourage developers and designers to jump in. You can also be surprised with the result.
