Klack plays the same sound at the same volume no matter how you type. Haptyk reads your real typing force using the MacBook's hidden accelerometer and adjusts the sound to match. It is the only app that does this.

via r/MacOS"This is the kind of whimsical app that could have been made in the late '90s and become viral via word of mouth. AfterDark vibes, good job!"
via r/MacOSTHE KEY DIFFERENCE
Every keyboard sound app on the market triggers a random sample when you press a key. The volume and tone never change. Haptyk is different because it reads the built-in accelerometer in your MacBook at ~1,000 times per second, correlates each reading with your keystroke, and selects a sound that matches your actual impact. Soft typing sounds soft. Hard typing sounds loud. It feels natural in a way no other app can replicate.
Haptyk is free to download with full velocity detection and one included sound pack. No trial, no account, no expiration. If you like it, Pro unlocks all 16+ packs for $8 one-time.
