The NIH Stroke Scale Calculator is a lightweight tool for quickly assessing the neurologic condition of a patient with stroke-like symptoms to determine the presence and severity of any neurologic deficit resulting from an ischemic stroke. The intuitive, responsive UI results in a much faster diagnosis than the standard pen and paper approach to the NIH Stroke Scale thus saving precious time during a potentially life-threatening or debilitating stroke encounter.

Verdict
The clearest difference is ads: NIH Stroke Scale Calculator at none against Eye Handbook's shown. NIH Stroke Scale Calculator also leads on rating (5.0 vs 4.8) and monetization model (free vs ad-supported). Eye Handbook's advantage is update cadence (every 3 weeks vs every 4 months) and ratings volume (1.2K vs 5). On price, in-app purchases, device support and iOS requirement there is nothing between them.
