About this app

Murphy is a hand-drawn spending diary for people who never manage to stick with a normal budgeting app.

Instead of typing numbers into boring tables, you doodle every purchase and Murphy, an AI potato accountant, reacts to your spending with a personality you choose: gentle, hype, nagging, blunt-fact, or savage.

WHY YOU'LL LIKE IT
- Draw your spending: leave a little hand-drawn doodle on every entry, from coffee to rent.
- Meet Murphy: your AI potato friend leaves a daily comment on your spending and a weekly letter looking back on your week.
- Pick a personality: from warm and encouraging to brutally honest, Murphy's tone is yours to choose.
- A calendar that becomes a diary: after a month, your calendar turns into an illustrated picture diary of where your money went.
- Simple stats: see category breakdowns, totals, and trends at a glance.

PRIVATE BY DESIGN
- No account, no bank or card linking, no ads.
- Your entries, notes, and drawings stay on your device.
- Only a short spending summary is sent when you ask Murphy for an AI comment.
- Analytics and crash reporting are off by default.

Available in English and Korean.

Murphy+ is an annual subscription with a 7-day free trial that adds more weekly story styles, AI rewrites in your chosen Murphy voice, and monthly recaps with story history. Your journal, first story, and weekly Tiny Purchases stay free.
