Retain is for tracking and education, not medical advice. Talk to your prescriber; never change a medication, dose, supplement, or exercise without your doctor.
What Retain does
- Logs your own health records and user-set goals.
- Shows static, cited education and population trial context.
- Offers free local export/import, optional Pro cloud sync, and account deletion.
- Uses consent-gated cloud AI for Pro plate-photo estimates and cited education summaries.
What Retain does not do
Retain does not diagnose, treat, recommend medication, calculate medication levels, set a dose, suggest titration, or tell you whether to start, stop, skip, change, or time a medication.
