TransectCount supports the species-specific counting of butterflies per transect section according to the European Butterfly Monitoring Scheme method. It is meant for transect counters to ease registering butterflies and day-flying moth during transect surveys.

New in Version 5.0.4:
- Bugfixes for version 5.0.3

New in Version 5.0.3:
- French and Italian languages added
- French and Italian example files added in GitHub Docs
- Added species: Adela reaumurella, Zerynthia cassandra, Cucullia artemisiae and Lithosia quadra
- A "0"-character (zero) in the section specific species remark puts the species also into the results despite a 0 count
- Exporting current DB and results creates the .db and the .csv-file name with date and time of the inspection start instead of the current time
- Counter alert function removed as hardly used
- Some data corrections
- Bugfix for problem with to quickly repeated counter clicks with button sound enabled

Features:
- Data collection is based on a transect inspection.
- Databases refer to a transect and can be individually created and customised within the app with regard to metadata, transect sections and expected species.
- The app contains an internal list with many European species and has a prepared database for a transect section with the most common species to be expected in Germany as a starting point for direct use.
- Export of the current species list for import by TourCount and TransektCount.
- Separate counters for internal/external counting areas and separately for ♂-♀-indeterminate, ♂, ♀, pupa, caterpillar or egg.
- Results page with prepared presentation for transfer to the input mask of Butterfly Monitoring Germany (web.app.ufz.de/tagfalter-monitoring/).
- The result can be output as an SQLite DB file or as a CSV table (e.g. for transfer and further use in a spreadsheet programme on a PC).
- The help contains detailed user instructions.
- TransektCount supports counting in German or English language.

Functions:
- Duplicate and delete transect sections.
- Editing the transect section lists (adding and deleting species and editing terms).
- Editor for metadata in preparation for an inspection.
- Counter page per section with scroll-down list for species selection.
- Species editor for annotation and bulk counter entries.
- GPS support for selecting the current section.
- The results page shows metadata, notes, totals and counting results per species and transect section.

Prerequisites:
The app requires
- storage access permit for importing and exporting counting data,
- the permit to set the screen brightness,
- the permit to prevent the sleep mode,
- optionally the permit for exact GPS location recognition.

The smartphone screen should have a minimum resolution of 1024 x 1920 pixels.
The app can be used with Android version 7.1 (Nougat) or newer.

TransektCount is one of two apps for monitoring European butterflies.
The second app, TourCount, supports the species-specific and individually GPS-localised counting of butterflies on any walk in nature.

Both apps use the coding scheme of Karsholt/Razowski for European butterflies and thus contain only European butterfly pictures.
