Keyboard sound apps for Mac, compared

Updated October 22, 2026

There are more than a dozen Mac apps that make your keyboard sound mechanical. They cost between nothing and $8, and they differ more in how they are sold and where their sounds come from than in what they do. Teclo's maker wrote this page, so Teclo is in the table; every fact about another app is cited to its own page.

How to choose

Try it on your own Mac first

How a keyboard sound feels depends on your speakers, your headphones and how you type, so hearing it in your own setup matters. Klack has no trial; its FAQ points to refunds instead. Teclo gives you 7 days and Klakk 3. Kiiwi and Teclo also let you hear the packs in the browser: try Teclo’s packs here.

Delay

In the reviews and threads we read, the most common complaint about these apps is a delay between pressing a key and hearing it, worst over Bluetooth headphones. Some apps now publish latency figures, from “11-13ms” to “sub-3ms”; those are their makers’ claims.

Recorded or synthesized

Most of these apps play recordings of real switches, and some of those recordings come from the same free sample sets. Teclo is the exception: it synthesizes every pack from a model of the switch, keycap, plate and case. That lets it offer sounds no keyboard makes, like Rain or Bubble, and keep every pack distinct, but it is not a recording of any one board.

Variety

A key that plays the same sample every time gets repetitive. Look for separate press and release sounds, several samples per key or per row, and some pitch variation. Klack and Teclo do all three; Kiiwi lists several samples per row and pitch variants.

Muting

If you type in meetings, check for auto-mute in calls or per-app rules: Kachunk, Tacque, KeyThock, KeyBell and Klack list one or the other. Teclo does not have them yet; you pause it from its menu bar icon.

Free

The open-source Thock is the free choice made for the Mac. Mechvibes is free on every desktop system and has the largest community library.

Teclo, briefly

Teclo is a menu bar app with 16 synthesized packs, from Butter to Typewriter, separate press and release sounds, mouse and scroll sounds, and a folder for your own WAV packs. A keycap pet sits on your desktop and powers up when you keep a fast pace. It costs $4.99 once for up to 3 Macs after a 7-day free trial.
