TourCount is an Android app that supports species-specific and individually localized registering of butterflies.


  • Data recording is organized for a tour in nature with its expected butterfly species.
  • The app comes with a prepared basic database with the most common species in Europe as a starting point.
  • Databases can be individually created and adapted within the app regarding meta data and expected butterfly species.
  • You may use an individual species list per region.
  • The app contains an editor to setup or adapt the current species list,
  • an editor to prepare the meta data for a tour,
  • an editor for individual species data of a count (e.g. state, remark or bulk count entry).
  • Counting page with scroll-down-menu to select a species and
  • separate counters for ♂ or ♀, ♂, ♀, pupa, larva or egg.
  • The app automaticaly inserts date, time, coordinates and height as well as
  • location data by reverse OSM-geocoding when GPS and internet are accessible.
  • Results are prepared for easy readout to transfer them to the science4you entry mask for butterfly registration.
  • Results are shown with meta data, totals, remarks, species results and individual data.
  • Results may be exported in SQLite- or CSV-format (for transfer to a PC for your own processing, e.g. in a spreadsheet.)
  • Help contains a detailed userguide.
  • TourCount uses the European coding scheme for butterflies from Karsholt/Razowski.


The app demands for

  • storage access permit which is needed for im-/exporting the counting data,
  • GPS permit for coordinates and location info per count,
  • internet access for OpenStreetMap reverse geocoding and
  • the permit to keep the device awake.

The smartphone screen should have a minimum resolution of 1920 x 1024 pixels.
The app is usable with Android Version 4.4 (KitKat) or newer.
