Fynn is your minimalist finance companion. Keep track of your accounts, balances, and everyday spending without the clutter, charts, or complexity you don't need. Open the app and see what matters. Adding expenses is designed to be effortless. Type or dictate naturally, enter the details manually, or let Fynn find transactions in receipts, bills, payment confirmations, and screenshots. Take a photo, choose an image from your library, or paste one from your clipboard. Fynn can even recognize multiple activities at once, so catching up on several expenses doesn't mean entering them one by one. With Apple Intelligence, Fynn understands natural language and helps turn what you type, say, or scan into activities you can review before saving. On supported devices, you can scan receipts directly with your camera, while Siri AI lets you interact with Fynn through natural conversation. Your financial data and AI processing stay on your device. The interface stays focused on your finances. See your total balance at a glance, manage multiple accounts and currencies, and open any account to browse its activity. Natural daily summaries highlight what matters without overwhelming you, while widgets bring useful information to your Home Screen and Lock Screen. Already tracking your finances somewhere else? Fynn can import existing data from Revolut and Cashew, making it easier to get started without leaving your history behind. Fynn respects your time and privacy. No ads. No subscriptions. No unnecessary complexity. It works with or without Apple Intelligence, with fast manual entry always available and optional gentle reminders to help you stay consistent. (Camera scanning requires a device with Apple Intelligence enabled and iOS 27.0 or later.)

See your money clearly, without handing over your bank login. Many expense trackers make you choose between linking your bank and entering each purchase by hand. Mieru offers another path. Choose a supported CSV or PDF statement. Mieru finds transaction rows on your device, suggests categories when it finds similar entries in your ledger, and lets you review every proposed change before it updates your ledger. On compatible devices, on-device AI helps Mieru read PDF statements. CSV imports work locally without a bank connection. Mieru never connects to your bank. You provide no bank credentials and maintain no bank feed. After you set up Mieruβs payment shortcut, an Apple Pay payment can open a prefilled expense for review. Your Shortcut passes the amount, merchant, and selected card to Mieru. You confirm before saving. Built for real life: β’ Track spending across cards, cash, and other accounts in their original currencies β’ Add transactions with categories, tags, dates, places, and recurring schedules β’ See spending charts and category breakdowns across the periods you choose β’ Review active and paused recurring costs β’ Share an encrypted ledger with a partner through a shared iCloud Drive or Google Drive folder β’ Export your data as CSV or an encrypted backup Private by design: Store your ledger only on this iPhone, in iCloud Drive, or in Google Drive. Backups and cloud copies are encrypted with your passphrase. Mieru has no ads, trackers, or in-app analytics that send your financial activity to us. Manual tracking stays private. Statement import adds automation when you want it. Why Mieru: Mieru comes from θ¦γγ (mieru), a Japanese verb meaning βto be visible.β Weβre a married couple, both engineers, and we built Mieru for our own lives: to keep shared money clear and calm without handing our bank logins or financial records to a personal-finance company. Nothing else fit, so we made it. See your money clearly. Keep it yours.

Verdict
The clearest difference is in-app purchases: Fynn at none against Mieru's 3. Mieru's advantage is update cadence (every 2 weeks vs every 2 months) and iOS requirement (18.6 vs 26.0). On price, ads and device support there is nothing between them.
