Morti is a fast, beautiful mortgage calculator that respects your privacy. Just type in your numbers and get instant results — no sign-up, no ads, no data collection. Ever.

INSTANT CALCULATIONS
Enter your property value, down payment, and interest rate. Morti calculates your payment in real time as you type. No buttons to press, no loading screens. Change the amortization with a slider and watch your payment update live.

FULL PAYMENT BREAKDOWN
See exactly where your money goes. Morti shows your principal and interest split, total cost of borrowing, and your exact payoff date. Switch between monthly, bi-weekly, and weekly payments to find what works for your budget.

YEAR-BY-YEAR AMORTIZATION
A detailed amortization schedule shows how your principal and interest change over the life of your mortgage. Visualize the breakdown with a clear chart, or scroll through the full table year by year.

TRULY PRIVATE
Morti is 100% offline. Your financial data never leaves your device. There are no analytics SDKs, no Firebase, no third-party trackers of any kind embedded in the app. We can't see what you type because there is no server to send it to.

No ads. No in-app purchases. No subscriptions. No "premium" tier. Every feature is available to everyone, forever.

NO PERMISSIONS REQUIRED
Morti doesn't ask for access to your camera, contacts, location, storage, or anything else. Install it and use it — that's it.
