Every time you maintain your car you need to remember what you’ve done, when, and when is the next time to do it again. Otherwise, you are jeopardizing your vehicle’s performance and your own safety. SeyanAgenda will carry this burden off your shoulders by keeping track of your car maintenance easily, accurately, and reliably. It has the following main features: “Home” – Displays a list of all vehicles you saved in your app, to choose any of them for editing its data, adding a new maintenance log, or even deleting the whole vehicle from your application if you no longer need it. “Add Car” – Save each of your vehicles' info to your app, edit, or delete them. “Add New Maintenance” – Add, edit, or delete every maintenance of your vehicle including its date, type, milage, and all details of that maintenance. “Maintenance History” – Displays a list of all maintenances saved for each of your vehicles. It also allows you to add a new maintenance, and edit or delete an old one. SeyanAgenda also supports both English and Arabic languages for display and entry, and allows switching between them at any time to suite all your needs. The great thing about SeyanAgenda is that all your vehicles’ logs are available in one place. You no longer need to remember / write down what you did and when. In a few minutes and bunch of clicks, get all your maintenance details recorded and tracked using your preferred language.
