Overview
About evenus
EvenUS is a fairness engine for couples that combines finances, chores, and the invisible mental load into one unified dashboard. It provides AI-powered insights, a live Household Harmony Score, income-aware expense splits, effort scoring, gentle reminders, and actionable tips to rebalance without blame or arguments.
Unlike traditional spreadsheets or basic chore apps, EvenUS treats money, tasks, and cognitive labor as an interconnected system, helping couples (married or not) reduce resentment, save time, and strengthen their relationship. Features include real-time syncing between partners, mental load tracking, fairness reports with Effort Balance and Financial Balance scores, Zone Ownership, automated reminders, and seamless integrations (calendars, banks, grocery apps).
Launching soon on iOS & Android with a generous free tier.
