Following graphs shows more than 2 years overview of project iKatastr on various platforms – web site, iOS, Android. Project iKatastr does simple stuff – shows cadastral map and enables user to tap on map and get information from the parcel registry (e.g. owner) in Czech Republic. Except Android version, all started at the same time 2 years ago for web, iPhone and iPad. All of the users of iKatastr are solely Czech consumers and thus reflect situation in the Czech app stores and web.
first graph shows how monthly sessions have evolved. Original thought that mobile launch of app iKatastr would boost web site visit failed. However after 15 months of runing iKatastr.cz web site and rephrasing some keywords for SEO it started dramatically to gain visits. Decline of iOS version in last 4 months is caused most likely by new project iKatastr2 that replaces the original one on iOS. iKatastr2 statistics is not yet revealed here.
second graph shows distribution of sessions among all platforms of iKatastr. 75% of all iKatastr sessions comes from mobile devices, while only 25% comes from web.
#1 iKatastr is still on top in the category Navigation in Czech app store after 4 months ! on iPhone it keeps 2nd place right after Mapy CZ provided by largest internet search in CZ Seznam. On iPad, however, iKatastr is still 1st in category Navigation.
#3 IKatastr has been mentioned in Czech magazine “Mobility” 1/2011, on page 85.
Quoted from the magazine press:
“There are just few high quality applications in the Czech App Store. Even fewer of them are for free. iKatastr developed at Mendel University in Brno belongs to this narrow group with functionality that is also unique in the international comparison. “
In short : it was a great experience – WP7 was smoothly registered, automaticaly connected to internet even without a SIM card using USB cable and Visual Studio 2010 integration just works perfect (so far:) In comparison to many difficulties and ‘certification hell’ on iPhone this is a great relief. Now giving the fact that Nokia is going to support and develop Windows Phone 7, great user experience with WP7 and (for me and menay others) great development experience, this might change the mobile landscape significantly over the 1 or 2 years.
I will guess here that WP7 platform will exceed number of iPhone applications in less than 2 years.
Update #3 02/2016 : this estimation was completely wrong , Windows Phone platform is nowhere, looks like great lesson learned – even you own great language and framework (C# and .NET) there is nothing that guarantees you being successful on emerging/disruptive platform/form factor. Objective-C (then Swift) or Java on Android got this mobile cake.
