Optional features include sending an alert silently through email or SMS gateway. An additional peace of mind for families with young kids. Works with or without a cellular account. Notes: • the app is intended to be an additional security measure, not a replacement to conventional home and travel solutions • silent alerts are sent as-is; while every attempt is made to ensure delivery, there may be situations outside our control which can prevent delivery • when running, battery usage is increased by less than 1% per hour
