🧮 DENKLEM – Mediation Fee Calculator

DENKLEM (from Latin "aequare" = "to equalize") is a comprehensive native iOS application for calculating mediation fees according to Turkish law. Written from scratch with SwiftUI, the app performs calculations based on the 2025 and 2026 mediation fee tariffs.

The name "DENKLEM" reflects the concept of creating equality and balance between parties, which aligns perfectly with the essence of mediation: establishing balance and fair resolution between disputing parties.
