About
Check79 is a private, local-first mental-health tracking app built around daily yes/no logging for the PHQ-9 and GAD-7. Instead of relying on memory to answer “over the last two weeks,” Check79 helps you log symptoms one day at a time and then rebuilds rolling 14-day scores and trends automatically.
Use Check79 to:
- Complete a quick daily check-in
- Backfill past days from the calendar
- Review a timeline of saved entries
- See rolling PHQ-9 and GAD-7 reports
- Inspect how each questionnaire item maps into the 14-day score
- Add notes and support resources
- Import and export your data in JSON or CSV
- Check79 is designed for personal tracking, reflection, and preparing for conversations with a clinician. Your data stays on your device by default, with no account required.
Check79 is not a diagnostic tool and does not provide medical advice, treatment, or crisis support. If you are in immediate danger or need urgent help, contact local emergency services or a qualified professional.
