Why is Offline Surveys not completely free like LimeSurvey?

The FREE version of Offline Surveys offers nearly the same features like the customized PRO version. The only limitation of the FREE version is a max number of responses that can be synced and surveys that can be locked (max = 10). But there is no limit at OfflineSurveys regarding:

  • the number of surveys you can use
  • the number of questions at your surveys
  • the number of Android multimedia questions you can use
  • the number of responses you can collect
  • features for exporting and emailing responses

We are only charging for features required by enterprises (AutoSync and Kiosk Mode)
