Reading and speech writing sms

I believe that technology should help to improve the quality of life, one of the ways is to use apps made specifically for this purpose.
Even if you believe you can download this app:
-listen to the phone number and the messages that arrive
- Respond to all incoming messages with predefined text or with any text (selecting auto-response)
-send voice sms
-also you can make the app run in the background: in this case will be notified when a text message arrives, tapping the notification will open the app and read or reply to the message automatically depending on the settings chosen
-holding the button with the microphone you can make a voice call
