Say It Backwards app is a sound recorder app with one goal - record a sound and play it back in reverse. Thats it. Such simple tool gives you enormous possibilities. I personally play with my kids and entertain my friends. Check how "NOW" becomes "ONE", and if you practice a little you can learn to say short sentences backwards. Listening to known songs, jingles or other sounds can be surprising.

Give it a try with English words: "easy", "Funny enough", "Amor Roma", "say yes" - those are all phonetic palindromes.
