I am very new to the piwik. In our application we want to build our own custom reports. For example a report showing the visits from android device and ios device. Can any one share me one sample example so that I can learn. And for doing this should we need to modify the tables?
Good news: we have now released the Custom Reports feature for Piwik!
Custom reports lets you choose which dimensions and metrics you want to see. You can combine multiple dimensions (up to 3) and as many metrics as you need.
The custom reports can be emailed to your partners or customers, and have their own menu entry in the Piwik report list. You can even setup advanced filters to further customise the reports.
Learn more about the power of Custom Reports in the user guide: Custom Reports - Analytics Platform - Piwik

and have a wonderful end of year!
