The best reply window on X is often the first few minutes after a major account posts. But notifications arrive late, the Following feed gets noisy, and by the time the post reaches you the conversation may already be crowded.
Pick the accounts that matter. Reply Radar monitors new public posts, ranks each moment by reply opportunity, and alerts you when there is a fresh opening worth acting on—without making you live inside the X timeline.
