What it is, in plain words.
HypoNavi: Mortgage Planner is a mortgage calculator and payment planner for anyone shopping for, refinancing or paying off a home loan. Enter loan amount, rate and term to see the monthly payment, total interest and payoff date, then compare scenarios such as extra payments, a rate rise or a refinance. It works offline, with no signup, no ads and no in-app purchases.
What is it?
HypoNavi: Mortgage Planner is a mortgage calculator with amortization schedules, scenario comparison and refinance analysis that runs on your device.
What problem does it solve?
A bank calculator gives one answer and asks for your details, while a home loan raises many what-if questions about extra payments, rate rises and refinancing. HypoNavi lets you test them side by side without filling in forms or sharing data.
Everything it can do.
Mortgage calculator
Enter loan amount, interest rate and term to see monthly payment, total interest and payoff date.
Amortization schedule
See how each payment splits into interest and principal and what balance remains, with monthly, biweekly or weekly frequency.
Scenario comparison
Save several scenarios, compare up to five at once and pin your top three.
Ready-made templates
Use 12+ templates such as extra monthly payments, a lump sum, a rate rise after fixation, a refinance with fees or a shorter term.
Refinance analysis
Model refinancing with one-time fees and an optional new term, and see the break-even point.
Automated insights
See what a rate rise would cost and how many years extra payments could save.
Charts
View balance over time, interest versus principal and cumulative interest.
Export and share
Export a PDF report, a CSV amortization table, plain text or a JSON backup.

Is it for you?
First-time buyers, existing borrowers weighing refinancing or extra payments, anyone who wants to stress-test a rate rise when fixation ends, and advisors modeling scenarios with clients. Results are for planning and are not financial advice.
Private by design.
The store listing says HypoNavi works offline, with no account, no telemetry, no tracking, no ads and no in-app purchases, and that mortgage data stays on your device. The privacy page lists file system access for exporting and importing data as the only device permission, used only when you grant it.
