"[Tacet's haptic metronome is its] killer feature" - Cult Of Mac
"Must have" and a "gem" - Macworld

The silent metronome where you feel, not hear, the beats. The simple BPM calculator always on your wrist. The handy tempo reference table. Tacet is 3 apps in one... and it is now better than ever.

Have you ever wanted to get a proper tempo, but don't know where your metronome is? Have you ever wanted a metronome without a loud, obnoxious sound where you can simply feel the beats as taps on your wrist? Have you ever wanted to check what the BPM of a song is, in one easy step? Have you ever wanted a handy reference table for common tempos? Have you ever wanted this all... on your wrist, with no need to even take out a phone?

Download tacet today! It is completely free, and we hope you enjoy it.

If you really love tacet, there is an option on the phone to support development for less than the price of a cup of coffee. No pressure, since the app is fully functional without purchasing this In-App purchase... but please give it a thought.

Please note that due to limitations in the OS, tacet will not run in the background or when the watch is asleep. As such, our users may find it better to use it for starting out with the right beat, checking if they are on tempo, and more, rather than while they are playing.

What's New

Version 1.2.1

The latest update to watchOS caused tacet to develop some, er, unexpected features (and by that, we mean bugs). Those are now fixed - and tacet has received an overall speed boost. Enjoy!

Great idea ruined by its hardware


There's a metronome watch on the market but since I already owned an apple watch I figured I might as well try this out. Even though this is the best that can be done at the moment, it's still pretty unusable because of the watch shutting off automatically after a few seconds. I'd love to donate if the developers ever figure a way around it but for now I wouldn't really recommend it

Such a great concept


Love this little app, and nice to see some bugs worked out.

Developer Response

Thank you very much for your download and your usage! Enjoy tacet!

Nice App (edited)


Handy, however, when I put my wrist down, it stops tapping. As a cello player, this isn't acceptable.

Great concept though!

EDIT: Understood! Thanks for the reply :-)

Developer Response

Hello, and thanks for writing. Unfortunately, this is a limitation imposed by Apple - developers, at the moment, have no way of overriding device sleep. That said, we have been in contact with Apple about this limitation, and hope that it is resolved soon.

In the mean time, we hope you still find tacet useful - for example, you could get a sense of a piece's tempo before starting it, or check tempo between movements (along with other features, like BPM calculations).

Again, sorry for this Apple-enforced limitation. If you have any more questions, feel free to reach out to support or update this review.
