This is a basic budget planning app developed to be used by semester abroad (Erasmus) students. Since I started this project with a momentary fad and don't have the motivation to perfect it, it might include basic bugs. In order to avoid most of them I would suggest being careful with the inputs. This application does NOT need internet access, it uses local_simple_database library which simply saves anything to a .txt file on your computer. Please do review the code before using it.
By using the "Deposit" option, have your different assets from different bank accounts under one roof. Use "Withdraw" option after spending money.
Set your planned monthly income (scholarship, allowance) and spending (rent, monthly subscriptions) from relevant options as well as your remaining duration of mobility (from "Settings") at the beginning of a month and receive monthly budget expectations. (Math behind it might need an update, use it with caution)
From "Travel Planning", set a name for your trip and determine the budget for it. Withdraw money as you spend it.
Records of your deposit and withdrawals can be accessed from "History" page. History records of your trips are accessible under the relevant menu.
