Monlio — Personal Finance Tracker

Monlio · FinTech

A calm manual finance app for iPhone and iPad — multi-currency accounts, crypto and stocks, clear reports, and optional iCloud sync without bank linking.

Offline-first · Multi-currency · iOS & iPad

Challenge

Most finance apps push bank linking, subscriptions and complexity. Monlio needed a minimal tracker for people who want clarity over their money — across everyday spending, savings, crypto and stocks — without handing over bank credentials.

Solution

  • Dashboard with net worth, account count and recent transactions at a glance
  • Accounts for card, cash, savings, crypto and stocks with live default-currency equivalents
  • Income, expense, transfer and exchange entries with categories, dates and notes
  • Reports with income vs. expenses, category breakdowns and period-over-period trends
  • Multi-currency support with ECB rates via Frankfurter, crypto via CoinGecko and stocks via Yahoo Finance
  • Offline-first SQLite storage with optional iCloud sync across Apple devices
  • Face ID, Touch ID or passcode app lock; sign in with Apple or Google
  • Light and dark mode, iPad layout, haptics and empty states on every screen

Result

Monlio delivers clarity without complexity — a private, manual finance tracker built for iPhone and iPad that stays out of the user's way.
