Cardio Calipers vs EP Calipers on Windows
Chief Executive Officer
Two honest tools for overlapping jobs
EP Calipers is a strong cross-platform ECG measurement app with a modern interface and QTc helpers. Iconico Cardio Calipers are a tiny always-on-top Windows overlay that sits on whatever viewer you already use. Many teams run both. This post explains when each fits, without pretending one replaces the other.
In a clinical setting, speed and reliability are paramount. Whether you are a nurse reviewing a strip at a workstation or a cardiologist analyzing a complex rhythm in a PDF export, having tools that integrate into your existing Windows 10 or 11 environment is critical.
Where EP Calipers shines
EP Calipers, developed by Jason Zey, is a purpose-built application for cardiac electrophysiology. It's particularly useful for users who want a structured environment for their EKG analysis.
- Cross-platform availability: Excellent for clinicians who move between Windows, macOS, and iOS devices.
- Integrated Analysis: Built-in QTc calculators and interval tools mean you don't need to leave the app for basic analysis.
- Store Convenience: Distributed via the Microsoft Store, which is a plus for institutions with strict application whitelisting policies.
Where Iconico Cardio Calipers fit better
Iconico's approach is different: we provide a measurement layer that floats above your entire desktop. This is ideal for teams that use a variety of specialized EMR and PACS viewers.
- Any viewer workflow: Open the EKG in your hospital's proprietary viewer, a PACS export, or even a simple screenshot. Cardio Calipers float on top, allowing you to measure without an "import" step.
- Paper-speed calibration: Stretch the calipers across 20 mm on the EKG grid, click 'Set', and the tool is calibrated. It mimics the physical experience of using calipers on a paper strip.
- Enterprise Licensing & POs: We specialize in bulk orders for hospitals. We accept purchase orders, check payments, and provide volume licensing that is easy for IT departments to manage.
- COM / SDK integration: For research teams or internal developers, our SDK allows you to embed Cardio Calipers directly into your own Windows tools.
Choosing the right tool for your department
If your goal is a standalone, modern app for EKG analysis that you can use on your phone and laptop, EP Calipers is a fantastic choice. However, if your staff is already measuring on scanned strips in legacy Windows viewers and you need a lightweight, reliable overlay that IT can easily deploy at scale, Iconico Cardio Calipers are built for that exact habit.
