I downloaded dozens of calling card and prefix dialers and ultimately decided to keep only this one.This application is very powerful, and allows prefixed, suffixes, dial digit replacements, pauses, etc.In a nutshell, it can do everything you might want to do when dialing numbers with calling cards, Skype to go numbers, using your phone I'm a foreign country that won't allow country codes to be used in dial sequence, or which requires local prefixes to be done.I am incredibly happy with its functionality. It does everything I want it to do and works with ios 10.However there is significant room for improvement in the looks of the application, and the instructions. The application is not intuitive and most people will probably give up. It requires a bit of basic programming mentality in the configuration of the macros, and some playing around to learn to use it. But if you do, I promise you that this is it! This is the one you have been looking for. Developer. Consider polishing the interface to make it nicer looking. Also, can you make a command available that does a replacement (example "+") only in the first instance following the command? Right now it applies rules to the entire dial string and it makes creation of the macro more difficult. However overall it's great. Thanks!

Works really well! Another feature that should be part of the OS but isn't. Interface not very polished, but this app allows you to to make changes to the telephone number to be dialed without re-entering the number in Contacts, and the macro-feature is brilliant! Once the macro is set up (again, programming the macro is a bit clumsy in execution, but very easy once completed), you just select the telephone number, select the macro, and presto the new dail string appears ready to be dialed. Great for entering discount IDD prefix's, call-back, etc. 4-stars only because interface is not that polished, but so what! Thank you Brice!

I find this app very useful as my dialing requirement changes when roaming between countries. This tool is specially helpful when roaming with carriers that have VoIP option, by dialing a special prefix, to get lower calling rates.I found couple of areas that I think the app can become more efficient for users like me:1. Direct access to the favorite contact list, instead of searching from the complete contact list. But over time the "recent dialed" list may address most of that requirement.2. Ability to easily manage which macro gets displayed in the macro selection window on the dialing screen will reduce the requirement to scroll through the long list of macros.Overall, great job by the app developer. Useful app.

Just watch out for the order of fields I had to play around to figure it out could use documentati
