Distinct key sounds for uppercase, lowercase & more

106 upvotes🎙️ AI Audio & VoiceAug 2026

Keytones is a innovative Mac utility designed to enhance typing awareness through distinct auditory and visual cues. By assigning unique sounds to different key groups—such as uppercase letters, lowercase letters, spaces, and modifiers—it helps users catch errors like leaving Caps Lock on without diverting their focus from writing. Users can customize pitch, length, damping, and volume for each sound group, or import their own audio files, creating a tailored feedback experience. For environments where audio feedback isn't suitable, Keytones offers visual feedback in the form of pulsing screen edges, ensuring users stay alert to their typing habits. With per-app control, Siri and Shortcuts integration, and instant mute options, it delivers a seamless, distraction-free experience. The one-time purchase model makes it accessible without ongoing subscriptions, making it ideal for writers, programmers, and anyone who values precise, non-intrusive typing cues.
