OPTIONAL REWARDS
Core calculations work offline. The app contains ads. Optional rewarded ads can unlock Share Plus styles and HD images, or a PDF export pass, for 24 hours. Standard image and text sharing remain available without a reward unlock. Ad loading and reward availability require an internet connection.

Financial figures are illustrative estimates, not guaranteed returns or financial advice. Actual loan terms, fees and rounding may differ. Project estimates depend on the measurements and assumptions you enter.
