Directions are good but will scam you on tickets – TMB App (Metro Bus Barcelona) Review

All the city advertisements will tell you to get the hola Barcelona card telling you this is for “ticket public transit” then this app will constantly try to force you onto the A1, A2 busses for the airport and the Nit Bus (any line starting with N) which is the only ones running after midnight. These are run by private companies and not the Metro. The is no way to say in the app that you only want public transit. Instead plan to pay for the Aerobus and buy a T10 or T50 ticket (10 or 50 rides) at the metro station that ticket will qualify for the Nit Bus.
