The Trial Version  is free and measures blood pressure for for seven days. You may repeat the test as many times as you like. It is offered as a public service and demonstrates the "look and feel" of our other software products. It will calculate your "typical" (median) blood pressure and will show on a bar graph the percentages of your measurements that fall in each classification from low to high. Try it and find out if you have elevated blood pressure.   Elevated blood pressure when untreated can lead to heart disease, kidney disease, stroke, and loss of vision. The Free Trial Version  is similar to the Standard Version, but with less features. Upgrade to our other products, the Standard Version, Advanced Statistics Version, Family Version , or Physicians Version directly from links on the Trial Version. These versions may be downloaded free from our Download Center. To activate them, just purchase an Activation Key from our Order page. Blood Pressure Profiler is a Microsoft Excel* workbook. If you use a different spreadsheet program from Excel* , you should download our Free Trial Version and test for compatibility. If the Free Trial Version works well and is formatted properly, our other software products will also work well. The download link below includes a free Activation Key! Open the downloaded Excel* file and read the "Detailed Instructions" page, which highlights the features of the Blood Pressure Profiler. Enter your blood pressure measurements for a week to determine your blood pressure classification and learn if you may have low, normal, high normal, or high blood pressure. This knowledge may be the first step in helping you to seek a professional evaluation from your physician. See our Measurements link to learn how to take your measurements.
