Definitely No. There are too many great apps out there and protonmail would have to be compliant with at least some of them. I do not expect many of my friends installing another im app

Yep, u are right.

Signal uses Google play services to communicate and needs access to your body sensors to do so. Please make a messaging app that doesn't need all of that information and allows me to click a contact and go straight to messaging them.

secure, private instant messenger/photo and file transfer app (phone-desktop crossover

Please don't re-invent the wheel. Signal is an excellent secure messaging app: https://www.signal.org

This would be a waste of Proton's resources.

I would totally use it

There is no need for proton to get involved in a messaging app.
Signal on mobile.
XMPP and OTR on desktop.

Hey, when you start build this messenger?

No.

The last thing we need is another messaging app crowding the field. People should be adopting other alternatives like Signal, or other Signal Protocol clients. Getting users off of FB Messenger, SMS, iMessage is hard enough - let alone a dozen competing standards

waiting for proton chat messenger app like fully encrypted security features ..

I would go with Wire Messenger.

Let ProtonMail do what it was designed for...email. There are plenty of secure messaging apps out there already. Give Signal a try.

would be interesting to see PMs take on this ... While I like the levels of security that Signal offers it's got a couple of limitations which bug me. Because I don't *need* that level of security for my family IM needs I use Telegram as my primary messaging client but it would be nice to have something that integrates with PM (single client install on mobile?) and offers Signal level of security/integrity with some of the user friendly Telegram features

I agree with using XMPP+OMEMO, Conversations.im already works well, it would be good to have a server with ProtonMail's security.

I would love a chat feature. Only because I feel many platforms are monitoring online chat and using it to restrict conservative groups.

not sure if this has been proposed, but it would be interesting to get a slack-like tool from Proton.

Keep in mind protonxmpp is not operated by Proton Technologies AG, of protonmail fame, but by some random guy hosted in digital ocean servers

Please Launch a Encrypted free messenger , thanks a lot

The only thing I could see them adding is something like a secure XMPP webclient since they seem to be interested in using open standards. And given that OMEMO is one of the major selling points for using XMPP for IM they could definitely do something especially if they also allow access over their onion site. But building a new app with a new scheme seems redundant given the existance of Signal & Wire.

I very much agree that enabling Protonmail XMPP services should be a top priority for all the reasons mentioned by the Op...
