Seems like its an android emulator attached to a real phone number.

One use could be to run something like whatsapp to have a virtual US presence if in another country, or maybe have a business number separate from your personal number and use whatsapp web interface to read/send messages.

I would absolutely use this.

I have a work and personal phone. For many reasons, it's very difficult to merge everything onto a single device. Further, I really don't need to do much "phone" stuff with my work phone. It's mostly a glorified pager, 2FA, and occasional Slack/Email. Anything serious gets a sit-down on my computer.

This would effectively let me carry a full-isolated, properly segmented work phone without having to carry two devices.

So you effectively want to merge your work applications onto your personal phone?

If your employer mandated use of a dedicated work phone in the first place, why on earth would they allow you to use this product to do that?

No, I want the isolation.

That’s the thing about this. It creates very clear and strong boundaries which are easily enforceable.

It lets me have a work phone on my personal phone without giving my employer any meaningful access to my personal phone.

Think BYOD, but without mixing personal and business data. So you can just open a browser on your personal mobile phone and access your work phone. Then, when you're in front of your (work) laptop, you just open a browser tab to access the same cophone instance.

(iPhone user here) isn’t there the concept of a “work profile” on Android phones to help segment work vs. personal?

Because you're a business and you don't want to use your personal phone, or get a whole new plan for a phone you have to lug around that gets very sporadic use.

That's not a made up use case; I think there are a lot of businesses that fit that description.

Main question I have is who is the target audience? If you're making this for work teams then it seems an app would be necessary. If you're making this as a burner line it seems there are cheaper options.

I am exploring having an app, I think that makes more sense for everybody.
