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!

What’s New

Version 2.0

Prefixer has been re-imagined for iOS 7 with a new design and new features! You now create Fixers, which can consist of either a prefix, a suffix, or both, and easily switch them on or off right within the app!

All new numbers added under "Home" label!

I use a long distance carrier that requires a prefix so this app looked perfect. Even had an enable/disable switch for when I'm on another network.

I used the feature to label the LD carrier. HOWEVER... when I enabled the prefix it added duplicate numbers (correctly prefixed) with a label of 'Home' instead of LD carrier. So now there are Home labels everywhere. Disabling the prefix leaves everything in my address book! - I guess because it can't find the LD carrier label ... Because it never added numbers that way in the first place!!

Faced with a huge cleanup. Did Apple even test this app?? Is this app a big practical joke?! Not happy

This app rewrites your phone numbers with the new prefix to your address book. Imagine what happens when you sync with iCloud and it uploads to the rest of your devices! Nightmare.
