DIS Diary is an app provided to registered users of Driving Instructor Services. This app will let you manage your diary and pupils via your mobile device, while updating the information to the DIS server, making the information available to call operators and potential pupils booking on your website. Some key features include alternating your diary between day and week view, checking your pupil balances, entering payments, booking appointments and sending and receiving messages. This app also allows you to use it while having no signal, updating when you re-connect.
