Even the best smartphone apps have been found deficient, especially in an emergency. A review of medical apps by a research team found problems. For instance when doctor reviewers entered information that should have produced warnings–like entering an extremely abnormal blood sugar. Only 28 of the 121 apps responded appropriately. Another issue found was the safeguarding of personal medical information–often sending reports by text or email.
PositiveTip; Don't depend on apps until their safety, accuracy, and privacy have been improved.
