From Mao Labs:
Contact Sendr is an application that lets you easily transfer all your contacts from device-to-device. It also allows you to easily share all or select contact information to multiple people across different devices. Maybe you need to share a client's contact information and photo to other coworkers or send a friend another friend's new number and email or share your contact information to a relative without an iPhone. You can do that in seconds directly from your iPhone with Contact Sendr.The simple and intuitive interface lets you quickly select, send, and sync your contacts. This app is also ideal for people who have recently upgraded to an iPhone 6S and want to immediately sync their contacts from their previous iPhone. No computer needed. Key Features:* Easy, wireless backup and transfer. You don't need a server or a computer to share or backup your device's contacts ever again. Don't risk losing your data with confusing syncing / Cloud services ever again. * Compatibility with different devices. The contacts are sent as a .vcf file (saving all selected contact info & photos) via email, which can be opened on any iPhone and Android device, as well as on your computer. * Select and send specific contacts. Don't just send a huge file with all your contacts. * Super simple and easy to use. No frills, just pick your contacts (or select all) and send.
