Prefixer

Prefixer allows you to quickly add prefixes and suffixes to numbers in your contacts. It creates new entries for all of your contacts, without deleting any existing information. For example, you can add a calling card number before dialling out a contact's regular number to save on long distance. When travelling, you may want to dial an access number before the number you wish to call; Prefixer is perfect for this kind of use. When you're done travelling, simply disable all the prefixes the app added with one button tap, and maybe enable a different one! Because the changes are added as an additional field in your contacts, you can call through with the added prefix or suffix without returning to the app, making for a clean, built-in solution that you can use in the Phone app, Contacts app, or even with Siri!
