Dd is turning 14 in October and has asked for a smart watch for Christmas but doesn't really know what she wants. She goes running and plays tennis, she also cycles to school. She likes the look of the apple SE and also entry level Garmin's although latter is quite big.
There have been so many smart watches e.g. Fitbit and similar but which watches are worth it now. At school she isn't allowed phones out but many students do wear fitness tracker type watches. They need to be taken off for PE.
