About this app

Lending money to friends, family, or colleagues is a common part of daily life, but keeping track of those informal debts can easily become awkward. Defterix is a premium, offline-first personal debt tracker and loan tracker built to remove the friction from personal loan tracking.

Whether you need a simple IOU tracker, a shared expense ledger, or an offline money tracker to manage money you lend and borrow, Defterix makes it easy to keep your shared balances clear. Set automated debt reminders, manage open balances, and track your money with absolute privacy.

WHY USE DEFTERIX AS YOUR DEBT TRACKER?

• 100% OFFLINE & PRIVATE MONEY TRACKER
Your financial records are your business. Defterix is an offline-first loan tracker, meaning all your loans, transactions, and contact names are stored strictly on your local device. We have no databases, require no account registrations, and do not track or sell your data. It is a completely private IOU tracker that works offline, even without cell service.

• SMART LOCAL DEBT REMINDERS
Never let a payment slip through the cracks. Defterix functions as a proactive debt manager by scheduling automated morning system notifications when a loan is due or overdue. Because it runs locally, no background servers track your notifications, keeping your reminders and alerts quiet and private.

• PREMIUM LEND AND BORROW DASHBOARD
Open the app and immediately see who owes you and who you owe. Tap on any contact to view detailed lend and borrow history, settle outstanding balances, or add new debt tracker records in seconds.

• PREMIUM DUAL THEMING
Enjoy a clean, state-of-the-art interface that matches your style. Defterix features a custom typography layout and transitions seamlessly between a crisp Light Mode and a battery-saving Dark Mode based on your system preferences.

• BILINGUAL SUPPORT
Fully localized and ready to use in both English and Dutch.
