This app helps you bulk update your contact list and add country code to the numbers. The contacts will be saved in international number format. And it is real fast.

You can filter all contacts that you want to add the country code.

We regularly add contacts in our phone without the country code. We face difficulty when we go abroad and then try to call our friends and family members. We have to manually modify all numbers one by one and add the country code in order to reach them. This app just does that.

This app also fixes issues when you cant find your contacts in WhatsApp and Signal.
