Ever typed a whole sentence in caps before noticing? Keytones plays a distinct sound for each key group (uppercase, lowercase, space bar, and modifiers) so your ears catch a stray Caps Lock before your eyes do. Tune Pitch, Length, Damping + Volume per group, import your own sounds, or, if audible feedback isn't an option, turn on Visual Feedback: a glowing screen edge that pulses with every keystroke. Per-app control, Siri + Shortcuts, instant triple-tap mute. One-time purchase, no subscription.
