• During illness — Open Care, start or open a care session, then use Add timer, Log temperature, or Add note in that session. Timers and Temperatures are now part of Care sessions when someone is unwell.
• Add a timer (everyday) — Start from Timers using the add action in the header (or the flow your screen shows for logging a dose / starting a timer). On mobile, show the Timers tab under Profile → Settings → Display & navigation if it is hidden.
• Add a temperature (everyday) — Start from Temperatures with the add action, or use Care during an illness episode.
• 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 +.
