Choose Radio Silence if you want the simplest blocker
Radio Silence does one thing. Add an app to the list and it can't connect, child processes included. There are no prompts and nothing to configure, and it's a one-time purchase.
Choose Drippy if you want rules and numbers
Drippy blocks apps the same way, and also single domains and whole blocklists. Rules can apply only on a chosen network, on metered networks, outside free hours, after a daily amount or near your cap, and can lapse after an hour or at midnight.
Because it's also a usage monitor, you can see which app is worth blocking before you block it, and how much it used on each network.
Questions
Does Radio Silence show data usage?
It shows live connections, not usage totals over time or data cap warnings.
Which is easier to set up?
Both need one approval in System Settings. Radio Silence has fewer options to look at afterwards.
