My Dad who has mixed dementia is forever getting confused using his Android mobile phone, so much so that he regularly just turns the phone off in frustation which doesn't help anyone. Rather than replace his actual phone with another simple to use device, I am looking into the possible use of an app. There are a some apps on app store but a few of them have negative ratings so can anyone recommend a tried and tested downloadable app for Android that is easily used? We just require simple phone functions only such as call/recieve/emergency and that the phone defaults to the phone use app screen on switch on. Many thanks
