User Reviews

Users praise the app for being simple, free, and helpful for planning mortgage payments across multiple loans, with clear numbers and fast calculations. However, recurring complaints center on calculation inaccuracy after updates and device compatibility issues that prevent startup. Ads and missing key features (semi-monthly payments, payment-number column) are noted drawbacks. Overall, it’s a powerful, easy-to-use tool when it works, but reliability and completeness could be improved.
Pros
  • Simple and easy to use.
  • Free to use.
  • Helps project savings across loans and walk through numbers easily.
  • Clear, plain numbers with fast calculations.
  • Helpful support from Karl when questions arise.
Cons
  • Inaccurate or inconsistent calculations after updates (payments can be wrong).
  • Compatibility/launch issues on some devices (e.g., GrapheneOS on Pixel devices) preventing startup.
  • Ads and missing key features or items.
  • Some users find the interface confusing or overly complicated for simple tasks.
  • Missing features like semi-monthly payments and a 'payment #' column in summaries.

this has helped me with over 100 deals, great calculator, It's strait to the point, no need for extras, calendar scheduling helped the most, it doesn't have comments or tips to follow you have to play with it for a bit, good thing it's strait to the point and easy to recognize. I do hope there will be more financial calculations with this calculator maybe with customize options for creative finance.

Beware!! calculates prepayment and extra payments incorrectly. Shows the loan paid off to early and additional payments are calculated to high.
