It took some training to be able to use it to its full potential, but it was definitely worth it. What is 75 days from today? How much will a $2000 payment buy? What will they save if the rate is .5% lower? Get it all at your fingertips! ### 5/5 — Best Mortgage Calculator out there *2023-03-30, version 10.5.12* This Calculator is a must have for any mortgage professional. ### 5/5 — Best ever *2023-03-08* I have been using this since 1993! Wow 30 years and now I have the app on my IPhone too. Best investments ever made. **Developer response:** Thank you for supporting us for all these years! ### 5/5 — My Qualifier Plus IIIx App *2023-02-13, version 10.5.12* One of the most worthy apps on my iPhone. I use it everyday for business and personal matters. I’d be lost without it! ### 5/5 — Can’t live without this app *2023-01-31, version 10.5.12* This is the mortgage calculator I learned on. I don’t use all the features but I couldn’t do my job without it. ### 5/5 — A Must have! *2022-05-14, version 10.5.4* I have been using the Qualifier Plus for over 25 years! As a professional loan originator and one of the top NMLS instructors in the Country, I insist my students purchase this app, if they are serious about their career. In addition, it is a must have for all real estate professionals! Sharon Butler, real estate trainer! ### 5/5 — Great for Realtors *2022-04-25, version 10.5.4* All Agents in my office have this on their phones. When we are showing properties, Buyers want to understand monthly payments. This is the BEST tool for Real Estate. ### 5/5 — What a Cash Grab!! *2022-04-11, version 10.5.4* I run a mortgage company and recommend this app to all my students. I used to have 3 of these physical calculators and was excited when I could buy it for my iphone. It used to cost $20 dollars one time payment in The App Store. But now I’m so disappointed that all of a sudden it costs $40 per year…every year!!! I don’t know what they did different to all of a sudden want to charge $40 per year just to use it?! 👎🏼👎🏼👎🏼 ### 5/5 — I’m a believer *2022-04-01, version 10.5.4* This app turned me into a math lover! It’s so wonderful and user friendly. I can’t say enough about this app. ### 5/5 — A must for anyone in real estate! *2022-02-03, version 10.5.3* If you don’t own this app, you need to. ## Most critical reviews (10 lowest-rated) ### 1/5 — Terrible new design! *2026-07-26, version 10.7.1* I’ve been using this for years and somebody decided to Royal screw up lipless seal? What the hell are you thinking? Your book is terrible. Please revert. ### 1/5 — Won’t pay a subscription for a calculator *2026-05-23, version 10.6.0* The app works well and the functionality is exactly what I need. I already purchased Qualifier Plus IIIx on Android and was happy to do the same on Apple. But a recurring subscription for a calculator isn’t something I’m willing to pay. I’d gladly buy it outright at a fair price. Please offer a one-time purchase option. ### 1/5 — Subscription for a Calc!? *2025-10-23, version 10.6.0* I was prepared to pay for the app until i saw the subscription. Their Master IIIx has been garbage lately, i have over 20 in my office and nearly half stopped working due to the batteries ### 1/5 — Good app but greedy developers *2025-07-17, version 10.6.0* I have multiple physical calculators as both large and small from Calculated Industries and I've been in the in industry for over 20 years, so I am not a stranger to this. That being said it is completely and totally ridiculous to pay monthly for a calculator when I have purchased multiple calculators throughout my career. I have no problem paying a one time fee (buying) for an app but the monthly subscription really shows how greedy the developers of this app are. I know this is something new as a few years ago you were able to purchase this app without a monthly fee. ### 1/5 — Click Bait *2023-09-14, version 10.6.0* App appears to be free with exception of ads. However, upon installation, you cannot proceed past the welcome page without paying six dollars a month for access need to put that in your summary and quit being deceptive. ### 1/5 — “In app purchase” *2023-05-26, version 10.5.12* Not to unlock premium features, have to purchase to use any features. Waste of time otherwise. Might have bought it if this was anywhere on the product page, just bait and switch ### 1/5 — Very disappointed *2022-09-02, version 10.5.4* I really enjoy the app itself. Functionality is great I bought this app in android ecosystem, and was planning to do the same in apple ecosystem. But I am not paying a subscription for a calculator. I think they are banking on mortgage professionals dropping annually for this app because they have the money. Just dumb. I wish we could go back to the days you buy something and own it. ### 3/5 — Perfect Financial Real Esate Tool *2021-12-21, version 10.5.3* I own the original physical calculator. I bought this when it fist came out. So convenient. Perfectly accessible. ### 4/5 — Olga ok *2023-04-04, version 10.5.12* Nice app but too noice ### 4/5 — Calculator *2022-05-15, version 10.5.4* It doesn’t keep or change the numbers I insert. I do not know why and how to change that ## Most praised reviews (10 highest-rated) ### 5/5 — Amazing! *2026-08-11, version 10.7.1* I have all the same functionality as if it was the separate device I used to own, but now it’s on my iPhone and I don’t have to carry a separate calculator around. What a dream. ### 5/5 — Sr.Loan Advisor *2026-07-27, version 10.7.1* I take you everywhere❤️ !!!!!! ### 5/5 — The best *2026-07-17, version 10.6.0* Love it use it 24/7 ### 5/5 — Must have for mortgage professionals *2026-01-07, version 10.6.0* Having all these tools on your phone is a game changer. I personally like the way you can email or text full breakdown of PITI to borrowers on different rates and loan amounts clearly and quickly. ### 5/5 — The Best *2025-12-19, version 10.6.0* 100%easy 2 use!! ### 5/5 — The qualifier *2025-05-31, version 10.6.0* I've been using Real Estate Master calculators for thirty years and am stoked that there's an app for it now! Like someone else said, it's one less thing to carry around. Thanks Calculated Industries! ### 5/5 — Excellent *2024-08-22, version 10.6.0* I’ve been in the mortgage business for 20 years. The physical calculator is what I started with - and to have this app readily available to help calculate payments/rates is pretty amazing. ### 5/5 — Best ever *2024-05-01, version 10.6.0* I have been using this since 1991! Wow 35 years and now I have the app on my IPhone too. Best investments ever made. Retire with Calculator soon. ### 5/5 — Essential Tool for all Lenders! *2024-03-29, version 10.6.0* Excellent tool for providing quick & accurate quotes anywhere, anytime. Highly recommended! I’ve been using qualifier plus for nearly 3 decades, no substitute. ### 5/5 — Best Calc *2024-03-28, version 10.6.0* This the best calculator designed for mortgage professionals --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
