About EP Calipers

epcalipersicon-180x180EP Calipers is an app that allows you to use electronic calipers to make measurements on images of ECGs or EP recordings.  See this post for more details.

EP Calipers is available for iPhone or iPad,  Android devices,  Mac, and Microsoft Windows™.  Click on the links in the previous sentence to go to the download pages of each version, except for the Microsoft version, for which see the next section.

Notes on EP Calipers for Windows

There are two ways to get EP Calipers for Windows.  The first way is to download a zip file containing the program, available from FastSpring.  Unzip the downloaded file and double-click on setup.exe to install the program.

The second version is available from the Microsoft App Store.

Both versions are identical in function.  Which version you should download depends on whether you want to have a self-contained version of the program or want to use the Microsoft App Store.  Both versions will run on 32-bit and 64-bit versions of Windows 10.  Updates to the program are free for both versions; however users with the Microsoft App Store version will receive automatic update notices, which is not (at present) possible via FastSpring.  Purchasers of the FastSpring version of EP Calipers will be emailed a coupon for free updates shortly after their purchase.  Email me at mannd@epstudiossoftware.com if you don’t receive this coupon.  Follow me on Twitter (@manndmd) to hear about new version releases.

It is possible to run the FastSpring version on earlier versions of Windows (back to Vista SP2!); however,  it is necessary to download the Windows Universal CRT update.  Please read the instructions of the linked page carefully to set up your system.

The latest version of EP Calipers for Windows (2.0.0 and later versions) happily now has a transparent window feature that is working well regardless of how you install it, from FastSpring or the Microsoft App Store.
