Name substitution app on Smartphone

[Nbj]

Hi there!

Before i ask the actual question, I'm not sure whether this even exists. I've read on some sites before that ppl installed an app on a phone so that specific word would be shown differently. Example: you recieve a message containing the word 'horse' and it gets shown as 'dog'
I'd love to be able to do this with my name because i often times can deal better with being gendered wrongly than called by my birth name.

Anybody knows such a tool?

Thanks
