RingNext: Offline android-specific Caller ID & spam app, ad-free.

Before this, I had released an app on the Google Play Store aimed at blocking spam callers in Mainland China, but without access to any databases of spam numbers, I could only use search engine data to make guesses, which obviously wasn't very reliable. However, today, on the first day of the Chinese New Year, I'm launching my new app on ProductHunt—RingNext. This app's goal is to provide Android users with a call-blocking feature that works offline. It operates on a simple principle: it blocks numbers that call for the first time within a 24-hour period, meaning if the same number calls a second time, it'll go through normally. It's pretty effective at defending against most AI-generated telemarketing calls. You might be concerned about the need for a whitelist system. Well, it has one—it treats your contact list as a whitelist and allows all calls from those numbers. I hope you'll find it useful. Happy Chinese New Year once again.
