MacWiFi

MacWiFi is one of those tools that makes you wonder why it didn't exist sooner — it monitors your internet connection and alerts you before your Zoom call crashes and burns, which is genuinely the worst. The concept is simple and the problem is universal, so execution is everything here. I don't have details on exactly how it detects flakiness or what platforms it supports, but if it actually works reliably, this is the kind of utility that disappears into your workflow until you need it.
