Most keyboard sound apps play a static click on every keystroke. Haptyk is different. It reads the hidden accelerometer inside your MacBook to detect typing force, then plays a matching keyboard sound in real time. Soft taps get quiet clicks. Hard presses get loud, satisfying clacks.
HOW IT FEELS
A gentle, quiet click when you barely touch the keys. Perfect for late-night coding sessions.
A crisp, satisfying mechanical sound for your everyday typing rhythm.
A loud, deep clack when you hammer the keys. Because sometimes you need to make a point.
THE TECH BEHIND IT
Apple Silicon MacBooks (M2, M3, M4 and newer) contain a hidden accelerometer managed by the Sensor Processing Unit. This sensor reads impact force and vibrations at approximately 1,000 times per second. Haptyk reads this data via IOKit HID and correlates each reading with your keystrokes in real time, with less than 1 millisecond of latency.
"Lmaooo, this is awesome! How did you come up with this? Where did you find the API for accessing this?"
via r/MacOS"Cool use of a little known feature. Honestly wouldn't mind some local analytics to show how often I press certain keys harder than others."
via r/MacOSWHY IT MATTERS
Apple designed the MacBook keyboard to be as quiet as possible. That is great for libraries, but terrible for anyone who misses the tactile feedback of a real mechanical keyboard. Haptyk brings that MacBook keyboard sound back without needing external hardware. Developers use it to make coding more immersive. Writers use it to find their rhythm. Keyboard enthusiasts use it because Cherry MX Blue on a MacBook just sounds right.
"My gf doesn't get it either. When I tell her I code better with it, she just stares at me."
Haptyk developer, r/MacOS"Anecdotal but my husband can tell the difference between my excited typing and my angry typing."

FAQ
Haptyk reads data from the hidden MEMS accelerometer inside Apple Silicon MacBooks via IOKit HID. It detects typing impact force at approximately 1,000 readings per second and plays a matching keyboard sound in real time. Soft taps get quiet clicks, hard presses get loud clacks.
Haptyk works on Apple Silicon MacBooks with M2, M3, M4 and newer chips. MacBook Air M3+ and MacBook Pro M2+ are fully supported. M1 Pro and M1 Max are confirmed working by users. macOS 13 Ventura or newer is required.
Haptyk is $8 one-time with a 3-day trial before you pay. The trial gives full access to all 16 mechanical switch sound packs and velocity detection (email required, no credit card). Pro keeps all 16 packs after the trial plus sensitivity tuning.
Klack, Mechvibes, and other keyboard sound apps play the same sound at the same volume regardless of how you type. Haptyk is the only app that reads actual typing force from the MacBook's built-in accelerometer and adjusts sound intensity to match. Soft typing sounds soft, hard typing sounds loud.
No. Haptyk uses a native C audio engine with AVAudioSourceNode for sub-millisecond keystroke-to-sound latency. The sound plays so fast it feels simultaneous with your keypress.
3-day trial with all 16 sound packs unlocked. Email required, no credit card. Pro is $8 one-time to keep them after.
