I created Sono [1]. It’s a debt manager app. I created it because in the past every time I lent or borrowed money, I used to note that in a text file. Eventually the file became really long and hard to manage. With Sono I just need to record the transaction whenever I borrow or lent money, it’ll help me to keep track of the debts. I learnt Flutter and built it in a year. Then I thought that maybe I could let other people use it and see how it goes :))
