The app is available to download for anyone aged 16 and over if they choose to do so. For some young people, particularly those with special educational needs and disabilities (SEND), parents will need to decide whether or not their use of the app is appropriate.
This aligns with wider NHS services which are generally offered to those aged 16 and over as routine. This will mean that some students in year 11, and the majority of students in years 12, 13 and in FE colleges will be eligible to use the app and benefit
from its features. Staff members will also be able to use the app.
