Your Discord server sends hundreds of messages a day. You care about maybe ten. Tempo Alerts filters the noise so only the right messages reach you — by keyword, by channel, by time of day. No more muting entire servers. No more missing critical updates buried in chat. Why users switch to Tempo Alerts: Keyword Filters — Set positive and negative keywords per channel. Only get notified when messages contain what you care about. Time Windows — Mute alerts outside your hours. Timezone-aware, so it just works. Live Activities — Follow server activity on your Lock Screen and Dynamic Island without opening the app. Real-Time Sync — Messages stream in live. No delays, no refreshing. Full Discord Rendering — Embeds, reactions, replies, attachments, and formatting — exactly as they appear in Discord. Message Analysis — Test any message against your filters to see if it would trigger. Fine-tune without guesswork. Channel Selector — Browse channels by category, toggle monitoring on/off, and set rules per channel. Built for Discord power users who need more than "mute" and "unmute." Set up in minutes. Customise everything.
