The main features of Lemon Tracking

Foreground application tracking. Records process identity, start, end and duration.
AFK separation. Uses the operating system idle timer and keeps idle periods separate from active totals.
Operational categories. Education & Learning, Social & Communication, Gaming, Passive Entertainment, Work / Productivity and Other.
Device-aware timelines. Desktop and laptop events appear by device row with clock-time overlap.
Manual history. Add a past session or a daily estimate with source and confidence fields.
Provenance preserved. Automatic, manual, estimated and imported records remain identifiable in history and exports.
Local exports. Export JSON and CSV with the event fields and codebook needed to interpret each record.
Data deletion. Delete today, a selected date or all tracked records from Settings.
