TT Rockstars maker to switch on daily time limits in all schools from 24 November

Bruno Reddy, founder of the firm behind the times-tables app TT Rockstars, said every school will have a curfew and a daily time limit switched on from 24 November. Leaderboards, which rank pupils, will be switched off by default. Labour MP Emily Darlington has warned at the Commons Science Committee that such apps could harm children's development.
