Our software keeps your electrolytes and your hydration at optimal performance. ------------------------------------------------------- Initial release.

ElectroKare is not to be held liable for any incorrect reports; damages; or liabilities, whether financial, physical, emotional, or other, as resulting from the appropriate or inappropriate use of and/or interaction with its services, app, or platform. The results presented by our platform are an estimation only. Before making any medical decisions, you must consult with a doctor. Our app is not intended to replace medical providers or standard diagnostic procedures, such as blood tests. We are not a medical company, and all data presented by our software are not to be interpreted as medical data. Our models make estimates on electrolyte levels based on your electrocardiograms, but the app does NOT directly measure your electrolyte levels in the same manner as is accomplished with a blood test. Our models are trained on our dataset of electrolyte data paired to ECGs. Several studies are available to support this relationship and the ability to estimate electrolyte data from ECGs. Some examples of these studies are here: 1. https://pmc.ncbi.nlm.nih.gov/articles/PMC8164149/ 2. https://www.nature.com/articles/s41598-024-65223-w 3. https://openreview.net/pdf?id=kNpLdJdBZT ElectroKare stores your electrocardiograms, activity information, and other user-provided information in a database so as to provide you with your analytics during activities and when looking through your history.

Our models are continuously improving, and we are occasionally updating them. Performance changes may occur from time to time as we continue to deploy new models.

SmartMS3's advantage is device support (3 vs 1) and iOS requirement (13.4 vs 17.6). On price, rating, review sentiment and ads there is nothing between them.
