Terrible company do not use!
The app does not work well and does not show timetables correctly. We bought their pass to travel to Sintra and Cabo de Roca with the understanding they come every 30 minutes. We waited for the first bus 50 minutes and our second bus over 60 minutes. Definitely a terrible company and a scam. A lady tried selling rides for 7.50€ in her personal vehicle because it took so long. Would be cheaper / easier to rent a car.
