Delaivery is an iPhone app that allows you to record voice messages and have them delivered to another phone number (or your own) at a specific time. You can even choose to have your message re-delivered hourly, daily, monthly or yearly. The recipients caller id will always show your number, so it appears as if youre making the call yourself. Its a convenient and easy way to have your voice heard exactly when you want it. Signing up is simple and its free to get started.
