Pronote is a school life management software created in 1999 by Index Education, and used in more than 10 000 high schools. It is initially a fat client, but since 2003, there is an extension that allows to use it as a web application: Pronote.net. Since 2008, Pronote is also available as a mobile application. (Wikipedia)
While this application is a great way to access your grades on the internet, there is one thing that all French high school students who stress about their grades will tell you: It lacks a notification system, a way for everyone to have access to their grades when they normally appear on the application.
That's when Pronotify appeared, which, thanks to the Pronotepy and Telegram APIs, makes the dream of all French high school students come true. Pronotify is a notification system that contacts (gives the new grade, the subject in which the grade was added, and the user's new average) whoever is using it through Telegram whenever there is a new grade on Pronote.
To test the app, you may deploy it on Heroku's (a script runner from server) platform, a free version of the subscription is enough to cover around 25 to 31 days of each month.
