KeiSignal

What is KeiSignal?

KeiSignal is a native Mac time signal app designed to let users hear spoken time notifications during the day. It places its controls in the macOS menu bar, making it easy to keep the app running quietly in the background while you work, study, or use your Mac normally. The app's main purpose is simple: it announces the time with Japanese voice audio and can also show notifications, giving users a lightweight way to track time without checking the clock constantly. Settings include options to mute sound during chosen hours, stop audio playback, or turn off notifications when you do not want interruptions. KeiSignal is suited to users who like audible time cues, character voice alerts, or a small desktop helper that stays out of the way. It is published by Akkeylab for macOS.

Key features

• Announce the time with Japanese voice notifications
• Run from the macOS menu bar for quick access
• Mute audio during specified hours
• Stop voice playback while keeping the app installed
• Turn off on-screen notifications when you want fewer interruptions

Safety overview

Status: Mostly safe

KeiSignal is a small menu bar utility for time announcements, so background operation and notification access are normal for its purpose. It may play audio and post notifications at scheduled times, which is expected behavior rather than a sign of harm. If you use your Mac in shared or quiet spaces, review its mute and notification settings so alerts happen only when you want them.

Recommendation: Keep KeiSignal if you use spoken time alerts or menu bar reminders as part of your routine. If you no longer want audible time signals, you can remove it without affecting macOS beyond losing its notifications and voice announcements.
