A butterfly monitoring app for species-specific registering of butterflies in Eu
About this app
TourCount supports species-specific and individually GPS-localized registering of butterflies.
New in Version 3.8.1: - Exported Excel spreadsheet improved - Code improvements - User guide and Help amended - Docs updated - Bugfix for getting start locality only once after app start - Bugfix for getting location metadata after Reset or Import Data
Features: - Data recording is organized for a regional tour with its expected butterfly species. - Databases can be individually created and adapted within the app regarding metadata and expected butterfly species. - The app has an internal pool of many European species and comes with a prepared basic database with the most common species in Europe as a starting point for direct use. - Separate counters for ♂-♀-indeterminate, ♂, ♀, pupa, larva or egg. - You may use an individual species list per region. - Results are prepared for easy readout to transfer them to the science4you entry mask for butterfly registration. - The results can be exported in formatted XLSX or CSV format, as well as in an SQLite database file (e.g. to transfer them to a PC, for easier reading in a spreadsheet program, or for further processing). - Help contains a detailed userguide. - TourCount supports counting in German, English, French, Italian and Spanish language and provides locale species names in these languages.
Functions: - Editor for metadata in preparation for an inspection - Counter page with scroll-down list for species selection - Editor for individual species data of a count (e.g. status, remark or bulk count entry). - The app automatically inserts date, time, coordinates and height as well as location data by reverse OSM-geocoding provided that GPS and internet are accessible. - The app provides functions to add, delete or edit the species for the current species list. - The results page shows metadata, notes, totals and counting results per species.
Prerequisites: The app requires permits for - storage access for importing and exporting counting data, species lists and results, - reading location data by GPS for coordinates and location info per counted individual, - internet access for OpenStreetMap reverse geocoding requests (locality info) and - preventing the sleep mode.
The smartphone screen should have a minimum resolution of 1920 x 1024 pixels. The app is usable with Android version 11 or newer.
Documentation is provided under https://github.com/wistein/TourCount/tree/master/docs.
TourCount is one of two apps for European butterfly monitoring. The 2nd app, TransektCount serves transect counters on their inspection walks. It supports species-specific counting of butterflies per transect section according to the European Butterfly Monitoring Scheme method.
Both apps use the coding scheme of Karsholt/Razowski for European butterflies and thus contain only European butterflies.

Installation Guide
Open Settings on your Android device
Go to Security → Unknown sources (or Install unknown apps)
Enable "Allow from this source" for your browser or file manager
Open the downloaded APK file from your Downloads folder
Tap "Install" and wait for installation to complete
Launch the app from your home screen
Make sure to re-enable Unknown Sources restrictions after installation for security.
How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be com.wmstein.tourcount is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 3.8.0 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall TourCount first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of TourCount, and a listing is removed when the evidence for it stops holding up.

Permissions Required
What each permission lets TourCount do. A highlighted one is worth a second look — not necessarily wrong, just worth asking whether this app needs it.
Previous Versions
The signing certificate fingerprint for this release is on record, so a build that does not match it did not come from this publisher.
