DTMFdec app for iPhone and iPad

DTMFdec is a highly sensitive DTMF-tone decoder which dynamically adapts to noisy or quiet environments.

Decoded numbers are stored in a list, from where you can perform actions like:
• dial number
• new contact with number
• add number to existing contact
• copy to pasteboard

Especially the "copy to pasteboard" feature is useful when you want to lookup the number in your local phone directory or just google for it.

DTMFdec is able to decode the following digits:
1234567890*#ABCD
