Hoops — basketball shooting tracker for the UNA Watch

Count makes and misses with one button press at 13 court spots, run built-in or custom workouts with rest timers, and read your results as a court map, category stats, highlights and a trend — all on the watch. Built on the UNA SDK with the LVGL GUI.

• Store text and screenshots: docs/store/listing.md, docs/store/previews/
• Workout builder (offline web page that reads and writes the watch's workouts.bin): https://the-hull.github.io/hoops/tools/workout-builder.html (source: tools/workout-builder.html)
• Built-in workouts: Software/Libs/score/presets.json
• Developer reference (architecture, build, self-test, decisions): CLAUDE.md

Build

Needs the UNA SDK checkout in $UNA_SDK, the ST GNU tools for STM32, CMake, Ninja, SDL2 and a Python venv in .venv/ (see CLAUDE.md "Environment").

export UNA_SDK=$HOME/una-sdk
# host tests (engine)
cmake -S Tests/Host -B build-host -DCMAKE_BUILD_TYPE=Debug && cmake --build build-host && ctest --test-dir build-host
# desktop simulator
cd Software/Apps/LVGL-GUI/simulator && cmake -S . -B build -G Ninja && cmake --build build && (cd build/bin && ./HoopsSimulator)
# watch app
cd Software/Apps/Hoops-CMake && cmake -S . -B build -DUNA_PYTHON_EXECUTABLE=$PWD/../../../.venv/bin/python3 && cmake --build build -j

Simulator keys: 1/2/3/4 = UP / DOWN / SELECT / BACK, Esc quits. Install on the watch by copying the .uapp to Apps/Hoops/ over USB mass storage.

Versions
