butce.app's answer:
Butce.app is the only budget app built specifically for how people spend in Türkiye. In Türkiye, almost every purchase comes with installment options across multiple credit cards. No Western app handles this. Butce.app lets you set the number of installments on any expense and automatically splits payments across future months on your financial calendar.

butce.app's answer:
People living in Türkiye who manage household budgets across multiple credit cards with active installment plans. Typically individuals or couples tracking monthly income, fixed expenses, loan payments, and variable spending in Turkish Lira.
butce.app's answer:
Built by a solo developer who could not find a budget app that understood how spending actually works in Türkiye. Every existing app was designed for markets where people pay in full. After tracking installments manually in spreadsheets for years, the decision was made to build the right tool from scratch.
butce.app's answer:
Python, Flask, SQLite, SQLAlchemy, Bootstrap 5, Chart.js, vanilla JavaScript. Each user gets a fully isolated SQLite database. Hosted on shared infrastructure with a focus on stability and data privacy.
