Hey Product Hunt! 👋 I built Groot because I was fed up with spam calls ruining my focus. Every productivity app tells you to silence notifications; but what about the 5 robocalls a day that still ring through? I looked at existing call blockers and found two problems: 1. Most require you to hand over your call data to their servers 2. The "free" ones sell your phone number to data brokers (ironic, right?) So I built Groot—a spam call blocker that: - Runs 100% on your device (nothing leaves your phone) - Is completely open-source (check the code yourself) - Gives you actual control: block numbers, countries, patterns, or whitelist the people who matter 3. No accounts. No subscriptions. No "we take privacy seriously" while harvesting your data. It's free because I think everyone deserves a quiet phone. I'd love to hear your thoughts: - What features would make this more useful for you? - Any spam call horror stories? (I've got plenty 😅) Thanks for checking out Groot!
