When using I’m Safe your contacts will be notified via SMS. But sending an SMS may not be enough… Past events have learned us that the cellular network might get saturated when everyone is sending or calling trying to contact their loved ones. In that case you can also add your social media accounts so the app can still send your message via Facebook or Twitter.
There’s also the I’m Safe extension for your smartwatch (Android Wear), no need to pull out your phone out of your pocket, just open the app on your smartwatch and tap the shield!
This app has been made possible thanks to Endare and Huawei.
