Set up a group once (Tuesday Toadstools, Year 3, the Thursday home-ed crew) and give it a term: the dates, the site, the times, the price. The app lays down every session with its register, its plan and its risk assessments ready, and one click puts the term on your booking page for families to buy whole or drop into. Skip half term with a tick. Next term takes two minutes, because the group remembers everything.
