- Add a timer — Start from Timers using the add action in the header (or the flow your screen shows for logging a dose / starting a timer).
- Add a temperature — Start from Temperatures with the add action.
- Add a family member — Open Family and use the add flow.
- Add a medication — Open Medications and create or edit an entry.
Exact buttons vary slightly by platform, but the idea is the same: go to the right tab first, then use Add or +.
