A recent report by HP showed that 80 percent of the vulnerabilities, which an app faces, are user's fault.
There is no app that can be considered invulnerable, though the security level may differ but all of them are at risk.
HP also examined about 180 Android and iOS apps and found nearly half of them leave data and personal information at risk.
iOS and Android platforms have the encryption capabilities, but if app developers don't integrate them into the apps properly, the encryption can't protect the data on the device.
