Pillcheek is a personal reminder tool only. It does not give medical advice.
Open iOS Settings, then Notifications, then Pillcheek, and make sure Allow Notifications is on. Then open Focus in iOS Settings and check that Pillcheek is allowed in the Focus you are using. Also check that the medication is not paused.
The Live Activity shows the countdown to your next dose on the Lock Screen and in the Dynamic Island, with a Taken button. iOS limits how long a Live Activity can stay on screen, so it can end after a few hours. Your reminders still arrive as notifications.
Add or edit a medication and set the dose amount. It changes in steps of 0.25, so 0.5 is a half tablet. For an as-needed medication, choose the As needed schedule, then tap Log a dose on the Today screen whenever you take one.
On your old iPhone, turn on iCloud sync in Pillcheek Settings. On the new iPhone, sign in with the same Apple Account, install Pillcheek and turn on iCloud sync. Your medications and history appear.
Open Pillcheek, go to Settings and tap Restore Purchases. Use the same Apple Account you bought with.
