## What is Calcium Pro?

Blood calcium, vitamin D, and osteoporosis are important health issues. The consequences of abnormal levels are often life-changing and occasionally life-threatening. Using this app is the equivalent to spending hours with the world’s most experienced doctors teaching you about your calcium, parathyroid, osteoporosis, and vitamin D issues. Your tests results are analyzed to determine if a problem exists, what risks are associated, and what to do about it. Beautiful graphs make understanding these problems simple!

Blood tests and bone density scans can be difficult to interpret—even many doctors do not diagnose calcium, vitamin D, and parathyroid problems correctly or timely. Hyperparathyroidism is a disease that affects 1 in 800 people and 1 in 250 women over 50 and is very often overlooked while patients suffer from chronic fatigue, memory loss, depression, osteoporosis, bone pain and many other symptoms. Calcium Pro is a powerful software program that will analyze your calcium health and provide you guidance about the status of your bones, kidneys, parathyroid glands, vitamin D, and other related health issues.

You start by entering your test results for calcium, parathyroid hormone, and vitamin D. Then we look at your bone density (osteoporosis levels). CalciumPro will analyze and graph your tests making them easy to understand. It will let you know the status of your parathyroid glands and your chance of having hyperparathyroidism. Suggested next steps are given. Tracking tools will show your calcium and vitamin D levels over time, and will show if your bones are losing density (worsening osteoporosis), or gaining bone density. There are important learning tools on every page, and an extensive video and reading library at the end. The app will provide guidance about talking to your physician regarding the possible need for surgery and other important steps.

A Risk Assessment Tool shows your relative risk for conditions associated with high blood calcium: Osteoporosis, Heart Disease, Heart Arrhythmias and Palpitations, High Blood Pressure, Kidney Stones and Kidney Failure, GERD, several Cancers, and others. Watch your risk assessment graphs change as you address your calcium problems. 

This app was developed by doctors at the Norman Parathyroid Center, the world’s leading parathyroid and calcium treatment center using over 4,000,000 data points from over 30,000 patients. Let the world’s leading doctors help you understand these problems so you and your doctor can make important, informed decisions. Take control of your own health!

### 5/5 — Great App

*2026-06-10, version 1.6.1*

First time user, and I am impressed. The results confirmed my suspicions!

### 2/5 — Data older than 3 years is ignored; results strange

*2025-02-25, version 1.6.1*

The app has a lot of useful information in it but the results are strange. I know it’s not a substitute for a visit with the doctor, but the conflicting results it gives didn’t help me figure out my next steps. More confused than ever!

First, your calcium/parathyroid hormone results > 3 years old are ignored when calculating your risk. After digging around, I discovered that’s on purpose. If you start out with your oldest labs first and they are > 3 years old, you’ll get error messages saying you didn’t enter anything when you did. That’s because the app ignores it. 

Why use only 3 years of data? The doctors are emphatic that people walk around with this condition for years, and the more information you have, the better. 

In addition, it doesn’t seem to factor in that you might be trending worse as time goes on, giving me a somewhat baffling interpretation.

For example, if I enter one lab at a time, look at the analysis with the needle, then delete it and enter the next one so I can see what each one independently says about my risk, I get the following results: 
3 years ago = UNLIKELY POSSIBLE cusp, 2 years ago = halfway through POSSIBLE, and in the most recent year = LIKELY/VERY LIKELY cusp. Getting worse, right?

But when these 3 years are all entered so that they are analyzed as a unit, the needle indicates the high end of UNLIKELY, with the needle LOWER than it was for any of the 3 individual entries!

Wouldn’t the most recent year = LIKELY/VERY LIKELY have more weight since it was recent and there’s a worsening trend? Why does it come up with a result that is LOWER than what each individual result says?

My labs from 2018, entered by itself using a fake recent date to work around the 3-year issue, put the likelihood as high as it will go, followed by several years of not-so-certain. Not sure why this bloodwork is not relevant to the app.

So bottom line is, I don’t know if I’m VERY LIKELY to have it or UNLIKELY to have it. So I guess I’m going to wait another few years until everything seems really obvious, right? This is what I’ve been doing for 7 years and I was hoping this was going to help me out, but I can’t make much sense of it.

A couple of small things to make working with this easier.

It would be nice to have the analysis button available after each data point is entered instead of having to back all the way out to get to it. I liked seeing how each entry changed the needle and it was a slog to have to keep backing out and then going back to enter another data point.

When editing the date, it completely jumps back to today’s date instead of keeping the date you had, so if all you wanted to do was change the day of the month, for example, you have to re-enter the entire date. Kind of annoying.

### 4/5 — Feedback

*2024-07-23, version 1.6.0*

Thank you for creating this tool. It has been very helpful in evaluating my condition. However, one inconvenience I encountered was that the tool does not store the data I input. As a result, I had to input my data repeatedly, which was quite time-consuming. It would be great if you could add a feature to save users’ inputs.

### 1/5 — Measurement Options Won’t Change

*2024-04-12, version 1.6.0*

I tried to load the Calcium-Pro app to add my information and try to pinpoint if I have PHPT or not as my labs come back, and am not able to add my lab values in, due to not being able to change the unit of measure selection to the correct units of measure. It seems that it is one line off… the selector changes the unit of measure for the next line of data entered below it for some reason (in app on iPhone). Hope they can get this fixed so I can update the review, and add stars/update review after the app is working correctly.
Thank you

### 5/5 — Crucial App Self Diagnose

*2023-09-27, version 1.6.0*

Your calcium numbers are “kinda high”. Nothing alarming.   

Maybe just under some range set by the lab but still high.  

But go back a few years and compare.  Are they always in the 10’s?  

Time to get a parathyroid hormone test added to your bloodwork.    

Show this app to your family doctor.   Show it to
Your friends and family.   

You don’t have to live in pain for years.

### 2/5 — Riddled with Bugs

*2023-07-05, version 1.6.0*

Sadly, the bugs mentioned by some people 2 years ago, have not been fixed. I have also found out that under the “My Analysis” section, the calcium/PTH, Vitamin D, calcium/vitD and osteoporosis sub-sections are not working. The app states: “You have not entered any data to graph “ - or the app does not provide a dot to let you know where you stand. It is very frustrating! Why would a reputable hospital creates an app, but does not follow up on its functionality?! Many patients will rely on an app like this one to convince their primary care physician to investigate their symptoms regarding hyperparathyroidsm because of a general lack of understanding, and then you are also being let down by it. Please, do fix your app!

### 2/5 — Not accurate

*2023-06-02, version 1.6.0*

Entered all my data from the past 10 years and says I have very low risk of kidney stones and hbp.  I have lots of stones. Including one 3cm one and have moderately hbp.

### 5/5 — Love Calcium-Pro

*2023-05-26, version 1.6.0*

Super easy to use and understand!

### 1/5 — Great idea, doesn’t work

*2022-08-03, version 1.6.0*

The description of the app sounds great, but it doesn’t seem to work on the iPad. After entering my test results, I can only click on one analysis tab, then the app locks up and I have to force quit. When I reopen it, I have to enter my test results again. I did this several times to see various graphs, but re-entering the test results every time is not a good user experience.

Don’t suppose I can get my $0.99 back for a non-functioning app?

### 1/5 — KB

*2022-02-22, version 1.6.0*

App analysis doesn’t work and is wrong. Don’t waste your $1 or your time.
