scout4all

scout4all is a free, open source app for volleyball scouting. It's built to cut the time it takes to record events while scouting, with an interaction designed mainly for the keyboard, but usable with a mouse or other devices too. The data you collect let you check statistics and analyze performance, during and after the match: side-out and break point, rotations, distribution, zones and trends over the season.

It runs on Windows, macOS and Linux; an Android app is in testing.

features

• scouting from the keyboard: pick the event, the player and the evaluation; the app follows the rotation, the phase and the libero, offers only what makes sense and keeps the score
• zones of play: serve and attack destination, reception, dig and block zones on a grid, plus set tempo and number of blockers, all optional
• substitutions, libero and setter changes, undo and correction of any event of the set
• match statistics, while scouting and afterwards: efficiency and positivity of each fundamental, side-out and break point by rotation, setter distribution, errors, trends rally by rally; filters by set, player, rotation, phase, role and quality of the reception
• team analysis over several matches (the last month, the last N, any period), with match-by-match trends
• DataVolley import (.dvw), with zones
• PDF report laid out as a scoresheet
• export and import of teams and matches, to share them with colleagues
• customizable keys, five languages (English, Italian, Portuguese, Polish, Japanese), light and dark theme
• automatic updates: at startup the app checks for a new version and, if you agree, installs it and restarts

scripts

Each one says at its top what it does, its options and what it needs.

script	what it does
scripts/test.sh	the tests as the CI runs them, in several time zones (UTC, Rome, Tokyo, Los Angeles); arguments go to cargo nextest
scripts/bench.sh	the times of the reads, of the statistics and of the scouting on large archives made of real DataVolley matches (downloaded once into a cache); generate DIR [TxM] keeps such an archive to try the apps on it, measure DIR times the reads on a data folder, scouting DIR the scouting of the match in progress of such an archive, reports DIR OUT writes the statistics of every match to compare them (diff -r) before and after a change
scripts/release.sh	releases the next version (major, minor or patch) from master: bump, commit, tag, push
scripts/generate_screenshots.py	the screenshots (and the video) of the desktop app for the site, in every language
scripts/generate_phone_screenshots.py	the screenshots of the Play listing, in every language, from the phone connected with USB debugging
scripts/country_names.py	writes core/src/shapes/country_names.rs, the names of the countries in the languages of the app, from the CLDR data
