A morning note at 8:00 your time, with what is on your plan today, or on a rest day the next session coming up. Days with more than one session list them all. Its first line is your coach's own, about yesterday's session or today's.
An evening check-in at 21:00, only when a session that day is still open, so you can mark it done, skip it or move it. On a day you have already ticked off, there is nothing to ask and nothing arrives.
A heads-up when a plan you asked for is ready, so you can lock your phone while it is written.
Turn Morning note or Evening check-in off in Settings, Notifications to stop either one. The plan heads-up stays.
A notification names the sport and how long it takes, never what the session is called and never anything about your health, because your lock screen is something other people can see.
