Mobile Text-to-Speech

Been wondering about text-to-speech applications versus our mobile system option of text-time-speech tool (Talkback) which I don't like using. Trying to find me a good application to help me as an interpreter the second I need to communicate instead of using one of the mobile to text "write" to each other. Sometimes I worry when anyone has my phone in their hand and accidently drops it or whatever.
