My experience with the SonoHealth company has been very good. They are responsive to issues and clearly working to better their programs via new features and fixed bugs. I recently had an issue after an update with their Android app that appeared to delete all the EKG-data I had collected over since installing the app. I submitted a ticket about the issue and within 24 hours I recieved a response informing me that they had corrected the issue with another update. I installed the new update and all my data was back! I very much appreciate that they are continuing to improve and work on their products and would recommend this to anyone who wants to more carefully monitor their heart health.
