A full view of your flex pool

Per call-out: who you reached, who read it, who replied and who signed up. Per pool: who is available, who you have asked a lot lately and where your database is thinning out. Per day: which shifts are still open.

Yes, delivered and read come in per message. A group chat or a broadcast list gives you none of that, there you only know you sent something.

Yes, the overviews can be exported so you can put them next to your own reporting.

Live. Statuses arrive as Meta reports them, so during a call-out you watch sign-ups come in rather than reading about it afterwards.

WhatsApp gives you separate chats and nothing else. No answer to who do I still need for Saturday, no view of how fast shifts fill, no way to compare one call-out with another. That is the gap this fills.
