Source on main is versionName 1.7.0 (versionCode 10). The application id is com.kaustubhtripathi.jaruri.
It tracks money and time: categories, budgets, charts, CSV import and export, and optional SMS import. Main does not use a Google account, Play Services, or a network permission, so the project can be built for F-Droid. It is not listed on the Play Store or F-Droid.
Jaruri binaries are not offered here until a non-debuggable release APK exists. There is no 1.7.0 package to install from this site.
