JAMR: Call Screen & Block

JAMR analyzes every incoming call in real time and shows you the risk before you answer — powered entirely by on-device intelligence. No accounts, no cloud analysis, no uploading your calls or contacts. MULTI-FACTOR RISK ANALYSIS Every call is scored across four weighted factors: - Area Code Intelligence — a complete US area code database with risk scoring built from FTC and FCC complaint data - Machine Learning — an on-device engine analyzing dozens of behavioral signals, trained by your own actions - Behavior Patterns — rapid repeat calls, rotating numbers, and robocall farm detection - Regulatory Data — FTC Do Not Call and FCC complaint records STIR/SHAKEN VERIFICATION See carrier-level caller ID verification status for incoming calls. Unverified and failed-verification callers are automatically escalated. CALL THREAT ANALYSIS OVERLAY An optional real-time overlay during incoming calls shows the risk level, location, and verification status — with quick actions to block, trust, or answer with confirmation for high-risk calls. LEARNS FROM YOU — PRIVATELY The adaptive engine improves from how you handle calls: block, whitelist, report, or answer. All learning happens on your device. Nothing is sent anywhere. SET IT AND FORGET IT Choose a protection preset that matches your comfort level, or fine-tune everything: risk thresholds, area code blocking, toll-free and international filtering, and more. YOU STAY IN CONTROL - Whitelist trusted numbers - Maintain your own spam list - Review every analyzed and blocked call with a full risk breakdown - Adjust or disable any protection at any time PRIVACY FIRST - All analysis runs on your device - No call log or SMS permissions - Your phone numbers and contacts are never transmitted - Risk data updates come from public FTC/FCC sources JAMR uses Android's official CallScreeningService — the system-supported way to screen calls, designed to work alongside your existing dialer.
