Teclo vs Klack
Updated
Klack is the keyboard sound app Mac sites write about: 9to5Mac reviewed it and Daring Fireball linked to it. Teclo does the same job at the same price, with a free trial, more packs and a pet. The real difference is where the sounds come from.

The short answer
- Pick Klack if you want recordings of specific real switches and you are fine paying before you hear it on your own Mac.
- Pick Teclo if you want to try it free for 7 days, want sounds beyond keyboards (rain, marimba, typewriter, arcade), or want the keycap pet.
Recorded against synthesized
Klack’s sounds are recordings: its FAQ says each switch set is “over 100 audio files that need to be recorded and mastered individually”. That is the strength people quote when they praise it.
Teclo records nothing. Its sound engine builds each pack from a model of the switch, keycap, plate and case, and renders the files the app plays. That is why it can offer a rain drop, a marimba or a typewriter with a bell on Return next to its nine keyboard packs. It is also why you should listen before you choose: every pack page here has a keyboard you can play in the browser.
What Klack has that Teclo doesn’t
Klack has head-tracked spatial audio, tone controls, a mute hotkey, “sleep triggers” that silence it in meetings or while music plays, and typing statistics. If you need the sounds to stop on their own during calls, Klack does that today and Teclo does not.
What Teclo has that Klack doesn’t
- A free trial: all of Teclo for 7 days, then $4.99 once.
- Packs that are not keyboards: Night, Retro, Arcade and Scifi.
- Scroll sounds and your own WAV packs.
- A keycap pet on your desktop that wakes up when you type, gets happier as you speed up and powers up when you keep the pace.
- Support for macOS 13 and 14.
