Check79

Track PHQ-9 and GAD-7 symptoms day by day, rebuild rolling 14-day scores, and keep your mental-health history private on your iPhone.

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.
