The best part about using this application is that it has very easy to use interface, which makes my job easier as I can easily create heat map with ease of just few clicks! And its free for basic version too!! It's not available in mobile app yet but i believe they will add soon because there are lot more users who want such kind feature so we must wait till then only!! Very helpful tool if you're looking out some new features or something related from geographical point view! As an analyst working at client side most often time our work depends upon data analysis done by us through GIS tools like QGis etc., So when ever user ask me any questions regarding same thing than what do other people think? What should be added/ removed / changed? Then openheatmap would help them solve their queries quickly without going back & forth between different websites (like google).
