Ringo lets you easily pick and use any MP3 music file as your ringtone - and set individual ringtones for each of your contacts and caller groups.

Ringo really powers up your SMS text message notifications too - set a different tone for each contact's messages, and control LED colors (when supported), caller or message sender voice announcing, pop-up notifications and more!

In fact, Ringo Pro allows you to customize almost every aspect of ring tone and SMS notification. If you are one of the many people who don’t notice the polite vibrating of the phone when it rings, Ringo Pro offers a much stronger vibration. Vibration patterns are aptly named: Discreet, Classic, Enthusiastic, Frenzied, and Relentless.

Ringo Pro will really shine as you start to apply its custom settings to caller groups and to individuals in your contact list. Each person can be assigned a unique ring tone, unique SMS tone, their own color of blinking LED (on phoens that support it), and a unique level of vibrate intensity. You will know instantly whether a call is from your brother, boss, or broker. One user sets a discrete ring tone and SMS tone as a default, then gives each important caller his or her unique tones.

Ringo Pro is packed full of customization options, so you can configure your incoming calls and SMS Text alerts exactly how you want them!

Please note that the HTC EVO 4G LTE currently has a problem with custom ringtones. If you have one of these and you don't hear the tone you expect for a call, you are experiencing this problem. HTC say they'll fix it in their next update.
