About this app

Take control of your loans and mortgages. Lessen gives you a clear and accurate view of your debts. Add your mortgages, personal loans, or car loans, and the app automatically calculates your complete amortization schedule: how much you pay each month, how much goes toward interest, how much goes toward principal, and how much you still owe.
Precise and detailed calculations. Forget spreadsheets. Lessen generates the exact breakdown of each payment using the French system, just like your bank. It supports fixed-rate, variable-rate (linked to the Euribor), and mixed-rate loans, with their corresponding rate adjustments. Always see how much you owe. At a glance, you can see your current payment, how much principal you've paid off, and your actual outstanding balance today. Simulate and save. Thinking about making an early repayment? Instantly see how much you would save on interest, either by reducing the term or the monthly payment. Notifications that matter
Get reminders before your payment due dates and, most importantly, a notification when your variable-rate mortgage review is coming up, so you know how your payment will change.
Your privacy first
Your financial data is yours and yours alone. Everything is stored encrypted on your device—no accounts, no logs, no cloud servers. Plus, protect the app with biometric lock (Face ID or fingerprint). Download Lessen and stop wondering how much you really owe.
Manage your loans and mortgages. You always know how much you owe and how much you have left.
