How it works
Thirds is a simple budgeting app built around one idea: every dollar (euro, pound) you earn belongs to one of three buckets: Needs, Leisure, or Savings. Choose the classic 65/20/15 split or the well-known 50/30/20 rule, and watch three clear rings tell you instantly whether you're on track!
What you get
• Three-way budget breakdown, visualized at a glance — no spreadsheets, no manual math
• Savings funds with goals - track an emergency fund, a holiday, anything you're saving toward
• Recurring expenses and income, entered once and tracked automatically
• Spending trends and category breakdowns, including comparisons across past months
• Import transactions from an Excel file, or enter them by hand in seconds
• Full backup and restore, so switching devices never means losing your history
• Choose your currency (EUR, USD, GBP) and language (English or Italian) - independent of your device's settings
Built for privacy
Thirds keeps everything on your device. No account, no bank connection, no cloud sync, no data ever leaves your phone. The local assistant that surfaces spending patterns and gentle nudges runs entirely offline too as a set of straightforward rules looking at your own numbers, not a chatbot and not a hidden data pipeline.
If you've ever wanted a budgeting app that respects the classic "give every part of your income a job" philosophy but without asking you to link a bank account or hand your financial life to a server somewhere...
Thirds is built for exactly you.
