What is it?

Distance From Me is an Android application whose objective is to calculate straight-line distances. Code is organised by features in a multi-module Gradle project, following MVVM + Clean architecture.

Features

• Searches places by keyboard and by voice.
• Calculates multi-points distances.
• Calculates distances from current position or from any position.
• Allows to show elevation profile.
• Loads and saves distances.
• Shares distances with friends.
• Shortcut to Play Store to rate app.
• Some FAQ.
• Languages: English, Spanish, French, German, Italian, Portuguese and Catalan.

Testing

The project has comprehensive test coverage for all critical components:

• 100% file coverage 🎉 - All ViewModels, Mappers, Repositories, Formatters, and UseCases have unit tests
• ~80% branch coverage 🟡 - Most code branches (if/when/else) are tested

For detailed branch coverage analysis, see BRANCH_COVERAGE_REPORT.md.

Run all unit tests

# Run all module tests with visual progress feedback
cd /home/david/projects/Distance-From-Me-Android && printf "=== RUNNING ALL UNIT TESTS ===\n\n" && for module in core-distances common show-info address faq opensource elevation settings app; do printf "📦 Testing: %s\n" "$module"; ./gradlew :"$module":testDebugUnitTest --quiet 2>&1 > /dev/null && printf "✅ PASSED\n\n" || printf "❌ FAILED\n\n"; done && printf "=== TESTS COMPLETED ===\n"
