Callro vs. RoboKiller
RoboKiller uses answer bots to engage scammers in fake conversations. While entertaining, the core blocking still relies on cloud processing and requires significant permissions.
Quick Answer
RoboKiller uses conditional call forwarding to route your calls through their servers and deploy answer bots. Callro processes everything directly on your device, preventing spam calls instantly without carrier-level forwarding or cloud dependency.

The Bottom Line
RoboKiller's answer bots are fun, but they don't actually prevent the call from reaching your device — they just redirect it. Callro silences the call before it ever rings, which is what matters when you're protecting a 75-year-old parent who shouldn't have to deal with any of this.
