Mäuse

Separate accounts. Shared life. Mäuse is the expense tracker built for couples who want to share everyday costs without sharing a bank account. The name Mäuse is German slang for "money" - a playful fit for keeping shared finances in balance. Record what you paid, choose a fair split, and always know what needs to be settled at the end of the month. BUILT FOR TWO • Track groceries, rent, trips, meals out, and other shared costs • Split by percentage or enter the exact amount your partner should cover • See monthly totals, your partner's share, and the current balance at a glance • Move easily between previous and upcoming months CAPTURE IT BEFORE YOU FORGET Open a new expense straight from a Home Screen or Lock Screen widget, the Lock Screen, or Control Center. Manual entry takes seconds. OR JUST SAY IT Optional Voice Mode turns what you say into expense drafts. Choose the mode that suits you: • Apple · On device – free. The AI runs locally on your iPhone, and your voice stays on the device. Say one expense at a time, check the draft, and save. For every iPhone with Apple Intelligence. • OpenAI · Cloud – more accurate, and captures several expenses at once using GPT-Realtime-2.1. Review drafts in a compact list, correct them by voice, and expand “What I understood” to see your requests and corrections in order. Requires your own compatible OpenAI API key. Animated feedback shows when Mäuse is listening or processing. Nothing is added to your expenses until you tap Save. ON IPHONE DUO Mäuse fully supports iPhone Duo and makes use of the larger screen when unfolded.
