My team adopted Geekbot as we transitioned from in-office to primarily remote. We tried a handful of tricks and tools early on, with Geekbot the stickiest. Spending 30 seconds submitting my report while getting up to speed each morning is an easy routine. Nowadays, I prefer Geekbot to in-person standups (and definitely don't miss the interminable ramble that they too easily fall into).
I think you're right to wonder about alternatives, though. The aspects of Geekbot we use would be fairly easy to replace with a bot of our own. Geekbot pricing has a very narrow sweet spot, which I imagine varies significantly by team.
