AudioNote Lite is a free recorder and notepad in one. You can create yourself a voice memo to yourself about what work you need to accomplish that night. To create a new note, press the plus sign in the upper right-hand corner. As the recording goes on, you can press the text "T" tool and jot yourself notes about important things mentioned in the recording. When you type, it creates a timecode of your text. When you listen to the note in playback mode later, you can press the link on the text and it will start from that moment.
My favorite function of AudioNote is that you can make a drawing by pushing the "/" slash key. This works the same as the text tool. If you are giving yourself directions and want to draw a left and then a right, you can do this. Like the text function, when you press the link on the drawings, it will take you to that timecode that you made the drawings in the recording. You can make the drawing during the initial recording, or during playback.
This application is great because it is free, but it always asks you to upgrade to the full version when you open the app. The upgraded version has unlimited recording and you can share notes by email and over Wi-Fi. That is the main problem with AudioNote - you cannot send the note anywhere. I recommend this application if you are just recording something simple, like you grocery list or even voice notes on ideas for your next radio script. If you are just recording a note for yourself, then it is fine, but if you need the audio to be sent somewhere, such as an email address or an audio editing application, you better fork over $4.99.
