My name is Richard Walters, and I am the developer of Calculator?. Last week I released a major update to the Windows Phone app, highlighted by this article on Windows Central: Calculator? for Windows Phone gets a huge upgrade, Windows 10 version coming soon | Windows Central. The update significantly improved all areas of what was already a highly rated app, and I'm very pleased with the end result. I hoped that my own satisfaction in the new version would be reflected by the Windows Phone community, but that has not generally been the case. There is a single reason for this; the Currency Converter, which used to be freely available, is now a premium feature.
Previously, the app included five calculators: Basic, Programmer, Scientific, Currency and Units. The app was free and supported by adverts, with an in-app purchase costing $1.49 to go ad-free. However, only a very small percentage of users paid for the in-app purchase -- almost all felt that it did not provide worthwhile value given that it didn't add any new functionality. The revenue generated by the app was not worth the time investment on my part to continue to support it, which would have been a great shame as I've very much enjoyed working on it and I know that a good many users find it useful.
In the latest version, I added a Financial Calculator, which is unlocked by the in-app purchase. I also made the decision to make the Currency Converter a premium feature, as it is the one part of the app that costs me financially as I pay a third-party for access to their exchange rates service. With this new monetisation policy, the free version of Calculator? provides the same core features as the new Windows 10 calculator (Basic, Programmer, Scientific, Unit Converter) although each feature is much enhanced, e.g. with the addition of scientific constants and ASCII buttons. The Financial Calculator and Currency Converter are then premium features not available in the OS?s inclusive calculator app.
The change in monetisation policy is to enable me to continue to support the app going forward. Unfortunately, I've received a multitude of negative reviews such as:
"Since upgrade you locked currency exchange. Not professional... So why one star..."
"Unimpressed with latest update disabling currency converter unless you upgrade to full. Uninstalled."
"Currency was free in previous version! :-( "
"Don't get it, the update makes it so you have to pay for everything"
"they ruined the app! I can't use the currency converter anymore
. they ask for money"
"Used to be easy to keep track of currencies in start screen. That has now become 'to be paid' ... I'll get my currencies somewhere else and look for another unit converter at the same time."
"The currency converter is locked after the last update. You will be prompted to pay for it. I have uninstalled Calculator?."
"After updating, many functions just got lost, and people who want to use those functions have to pay. But they were free in last version!"
The average daily rating for the app dropped from ~4.25 to 2.75 in the days after the update was released. And yet it is a much improved version of the app. I must say that some users have kindly contributed very positive reviews about the update too, although they are not the majority.
Let me put the case for the change in monetisation this way. I have actually taken three months of unpaid leave from my current job in order to work on the app full-time and release this latest version. I have taken a huge hit financially in doing so, but I?ve very much enjoyed this period of my life. My hope is that over time, the new monetisation policy will help recoup the loss of income to make this venture worthwhile. It remains to be seen if this will be the case. The point is, I would love to work as a Windows app developer full-time and release other apps in addition to Calculator?. If only 10% of the people who downloaded the app decided to purchase it, then this would be possible for me. Unfortunately, the ratio is nowhere near that number, even for such a high quality app as Calculator?. At $1.49, the cost of the in-app purchase represents fantastic value ? it is much cheaper than a handheld scientific calculator with the same level of functionality, much cheaper than a coffee from a coffee chain, or a pint of beer from a bar. It is only a fraction of the cost of the phone, which without apps would merely be a very expensive device for making and receiving calls. If more Windows Phone users were willing to support developers, then there would be a lot more Rudy Huyn?s out there working full-time on creating wonderful Windows Phone apps to help fill the app gap between Windows and the other mobile platforms.
My hope is that this post will raise awareness of developers motivations for charging for content in their apps. I also wish to spark a debate so that I can further understand the consumer's point-of-view and thereby cater more sensitively for their concerns.
