### 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❤️ !!!!!!

### 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.

### 5/5 — The best

*2026-07-17, version 10.6.0*

Love it use it 24/7

### 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.

### 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!!

### 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.

### 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!
