Sublimental

Sublimental is a simple auto-suggestion app that will play your pre-recorded self-help messages, alongside your music and your generated self-help text alongside a favorite picture from your photo album as a backdrop.

* Pre-record any audio message you wish to play back and control playback frequency and intervals.
* Adjust the playback volume of your message to be as subtle as you wish.
* Type in your favorite mantra message for display and choose your favorite photo as a backdrop for your self-help messages.
* Mix-in your favorite music and off to self-improvement land you go!

And its free!

Note iPodTouch users: You will need to plug-in headphones that contain a microphone in order to record. iPhone users already have a built-in microphone.
