Record any sound, play it backwards.
Just have fun or seek for backmasking :)

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.

While making this app I have realized there is a whole conspiration theory about backmasking - give it a search on Youtube or Wikipedia - you will be suprised. My favourite one is "Oh no, you're playing the record backwards. Watch out, you might ruin your needle" ... at least using Say It Backwards app you will not ruin your needle :)
