CastleID

Instead of manually entering and managing a bunch of other peoples' contact details in your address book, you load your own details into the app and decide who you want to share with and which data you'd like them to have. The app then automatically pushes the right data directly into each others' native contacts app. The CastleID app does a few simple things:

1 - It lets you update your own contact personal information (phone, email, address, etc.) so if you move, change providers, or just feel like switching it up, you can easily update all of your friends/family/colleagues/etc. with the new information in a pain-free way.

2 - It gives you control over what information you share with your CastleID connections so you don't have to share every piece of personal information with everyone. It's customizable and puts the power of your contact details back in your hands.

3 - It automatically updates your native contact app with any contact information that your connections are sharing with you through the app (and vice versa will update their native contact app with your details). This means you never have to update your contacts again - you can have confidence that the phone number you're calling, or the address you're sending that holiday card to are accurate and up to date!

** Note – CastleID will automatically update the contacts in your native app so you may want to back them up in advance of using the features of this app
