I’m torn on these apps - they are an absolute godsend for new managers (because the usual practice, as you note, is “sink or swim” with bonus sharks thrown in for free). But they can become an issue later on, because they are trying to mediate a human interaction through an app.

Given that most managers are relatively new, I’m still hoping you have vast success :)

But there’s also a key bit of feedback in there - you might want to ensure there’s a good solo experience in there, too. That will also help you get into entrenched IT departments at large companies - you might not get the sale to the whole company off the bat, but you can capture key internal voices (if they can run your app without security concerns and off the corporate network)

Either way, good luck. Managers deserve all the support they can get, and engineers deserve better management.
