NoRing
Free Private Call & SMS protection that learns on your phone
NoRing gives you a quieter phone with adaptive, on-device call and SMS protection. It learns from unknown calls you reject or end quickly, then recognizes repeat and similar number patterns as unwanted callers rotate numbers, helping them stay quiet before they ring. Important and uncertain SMS/MMS stay in Inbox, while likely promotions and suspicious messages move to Quieted. Everything is processed privately on your phone. No account required, free to use, and available in 30 languages.
Hey Product Hunt 👋
I built NoRing because blocking one spam number rarely solves anything. Another sales call usually appears from a slightly different number.
NoRing learns locally from the calls you reject or end quickly. It recognizes repeat and similar patterns on your phone, so matching callers can stay quiet even when the number changes. Everything is learned and decided on your device. 📵
It also keeps useful SMS/MMS in Inbox and moves likely promotions to Quieted, without deleting them.
NoRing is free, needs no account, and is available in 30 languages. 🌿
A quieter phone. More of your life.
to do this well on Android you'd basically need to read call logs and SMS content, which is a pretty deep permission ask for an app with no account and no visible company behind it yet. two questions: is this using the official Android CallScreeningService/SMS-app APIs (so it's sandboxed the way the OS intends), or does it need to be set as default phone/SMS app to work? and since everything's on-device with no account, how does detection get better over time, is there any anonymized signal going back to improve the model, or is each phone's "learning" fully isolated to itself?
"Learns on your phone" instead of relying on a central blocklist is an interesting privacy-first approach. How long does it typically take to start reliably distinguishing spam from legitimate unknown numbers once someone starts using it?
