Tuta (formerly Tutanota) did it.
Why Proton can't did it yet?

Please implement this in your next "change order" or "sprint cycle". Enable us to completely separate ourselves from the BigTech web. Far too long have these walled gardens kept us constrained and vulnerable to their ownership.

This is huge. Need it to replace the Google contacts app.

Dedicated IOS Contacts app would round out an already great suite of tools.

If Proton create a softphone app, then please integrate it with that as well. Being able to associate different contacts with burner phone numbers would be awesome.

This is critical. Also integrate Contacts with Calendar.. so calendar shows birthdays and anniversaries specified in a contact.

Oh also I'm not sure about integrating with the on-phone contacts. Seems like that would compromise security. But I guess what people really mean is to be able to save contact information to the app easily, and one-click phone calls and email (which I believe already works for contacts in Proton Mail).

In addition to the great ideas above, it's critical to have easy EXPORT of contacts. If Proton stops working at some point in the future or one decides to move, you must be able to export contacts easily.

I suggest a Proton contact app, with synchronization with the Proton account, and with the possibility of having the contacts appear in the default contact app on the Android smartphone.

All encrypted, of course.

That's the only reason I haven't switched to Proton yet. Once contacts can be synchronized with the phone's address book, there's nothing to stop me from switching COMPLETELY to Proton.

I have a paid Visionary account along with my wife. We are both retired from successful business and have a lot of shared contacts. We have blown out Google everything and moved to ProtonMail, Shared Proton Calendar, and Shared Proton Pass on our family's accounts and passwords. All we are lacking is to have shared Contacts. That would complete the sweep for Proton. Please allow us to share contacts!

This is the one thing Proton should consider before adding other apps. I feel it should be at the core of it all. I want to have my contacts in one place, syncing with my emails, a new Proton chat app, my calendar, etc.

The Proton Mail contact book is one of the oldest components of the Proton user experience. And it feels like it as a user. Data entry between Web and Mobile is not consistent. There is no client-side personalization when browsing contacts based on information in the contact. Data like contact birthdays does not appear in Proton Calendar. Data entry is a hassle, and data entry experience on mobile is not great. The Proton contact book is also exclusive to Proton Mail, which means any Proton user who has a mobile phone is likely either maintaining two contact books, or chooses to only use one and ignore the other.

It is time. Proton Contacts needs to become the next cornerstone app in the Proton product family. Instead of being an oddly-integrated part of the Proton Mail experience, graduate the contact book from its humble beginnings into a true competitor that rivals contact solutions from Office 365 and Google Workspace.

For Business users specifically, Proton Contacts is the missing enabler that would give the Proton product suite the ability to compete at a foundational level with Office 365 or Google Workspace. For Proton Business customers, an address book can be one of the most important parts of an organization. Imagine how useful it would be to provide an organization-wide contact book maintained by admins, while allowing each user under my plan to maintain their own contact book as well.

The improvements and maintenance to existing apps plus the advancement of new and exciting apps from Proton is great. The Proton product family is very strong, and great UI/UX makes complex security details seamless and invisible for people who don't care how GPG encryption works. But the Proton Mail contact book is one sore spot in the Proton product family that needs love and attention. It is awkward at best. This would be a nice complement to the highly-upvoted idea for a Proton Contacts mobile app.

Proton Contacts is the missing enabler that would give the Proton product suite the ability to truly compete with Office 365 or Google Workspace. Proper mobile support for Proton Contacts separate from the Proton Mail app is the next right step to make the Proton product family a real competitor for any privacy-conscious user or business/organization.

Agreeing with the below comments. How can we get completely away from Google without a Proton contacts app?

It's the only item preventing me moving totally off gmail.

HOW IS THIS NOT A THING YET!?!?

this has been here since 2022 and rudimentary version of it is already integrated into Proton Mail. What's the hold up?

This is about the easiest thing to do...
If storage is an issue, use proton drive to store the info.
If it's the UI, you've already got one in Proton Mail, just move it to it's own page.
If it's the app, use an open source app as the base

I want to move completely away from "Big Tech" but not having contacts sync or regularly backed up is a REALLY tough sell for many people who want to simply move without hassle

I would also like a dedicated app

I would like to have an dedicated Proton app for Contacts on iOS!

Agreed, how can I degoogle if I can't export my emails, calendars AND CONTACTS to seperate apps. My contacts are shared between emails/calendar life on PC/smartphone and phone app on my smartphone like in Google/iOS. Any nex contact that goes into my phone needs to sync with email/calendar contacts and vice-versa like in Google.
