The app records what the user tells it and never advises

Context

Anything that reads like medical guidance (a suggested dose, a warning about two medicines, “you can take another”) makes the app a medical device in the regulatory sense and a liability in the ordinary one. Play’s Health apps policy also asks every health app to say whether it is one.

Decision

The app stores the user’s words and the clock, and makes no claim about medicine. The Amount and Note are free text, never parsed, validated or compared. No list of medicine names ships or is fetched. No copy uses advisory words (CONTEXT.md, Words we deliberately avoid). First run and the listing say once, plainly: this is a reminder, not medical advice and not a medical device; ask a doctor or pharmacist about your medicines.

Alternatives

Interaction warnings from a bundled dataset. Useful, and wrong the first time the dataset is stale or the user’s spelling differs, with the app’s name on the advice.

Structured Amounts (“2 × 500 mg”) to drive Supply. Supply (phase 4) instead counts units the user declares per Medicine, so the Amount stays text.

Consequences

• Autocomplete only ever offers names the user has already typed.
• Supply counts down by a number the user sets per Medicine (“each Dose uses 1”), not one read from the Amount.
