Every Realtor or real estate investor needs this app!!! ### 5/5 — Best Mortgage Calculator on the Planet! *2019-03-15* Love this app. So simple to use and dead on accurate. ### 5/5 — Easy & Intuitive *2016-01-18* I like the design of this app. It's really easy to slide the numbers around and see the results for possible loan situations. Thanks for updating for iOS 9! ### 1/5 — App Doesn't Load in iOS9 *2015-11-24* I had the free version, but it didn't load in iOS9. So, I popped for the paid version. That doesn't open in iOS9 either. Looking at the reviews, nothing's been going on in this app for 5 years. Ryan - either make your product work on the current iOS or remove it from the App Store if that's more than you can handle. I would like a refund, please. **Developer response:** Sorry for the poor experience. The app has been updated and should be working on iOS 9 and newer now! ### 2/5 — Not great for paid app *2010-12-06* Doesn't take into account pmi, extra payments, taxes or anything. Not helpful at all for me. Needs more, especially if it's a paid app. ### 5/5 — Great app. Worth the money. *2010-07-23* It does what it says. Super easy to use. ### 2/5 — Slides everything but the term *2010-07-09* Good interface, but I want to slide my payment to see how quickly I can pay off my loan -- instead of adjusting the term, it adjusts (increases) the loan amount. WTF?? Please add this basic functionality... :-( ### 5/5 — Quick changes on the fly *2009-07-24* This app helps you get an idea how much your monthly mortgage payment will be based on Loan amount, Interest rate and Years of term. After setting any amount or variable, it is very easy to "slide" each category and see the changes instantly. Totally helpful in working out what you'll be paying monthly. Very handy. ### 5/5 — Easiest Mortgage Calculator Ever *2009-07-14* I downloaded this mortgage calculator and it's absolutely the easiest to use of any that I've found. It's handy and actually fun to use. ### 5/5 — Simple! Easy! Fun! *2009-07-13* Works great! Easy to use...by far the best Mortgage Calculator out there! ## Frequently asked questions about Slider Calc ### What is Slider Calc?
