Hello! Before I begin, I should mention I am 15, so if you run into any issues with tacet or have any feedback, PLEASE let me know - I want to learn. I am the developer behind tacet (https://itunes.apple.com/us/app/tacet-haptic-silent-metronome/id1039646461?mt=8) the silent haptic metronome, BPM calculator, and handy tempo reference table for Apple Watch. I launched it several months ago, and the response has been amazing. I got so much great feedback, and today I am proud to announce the next major release, tacet 1.1. The new version brings a variety of new features, from interface improvements to a better BPM calculation algorithm to improved haptic feedback. Tacet allows you to have a silent metronome always on your wrist, where you can feel the beats (without an annoying audible tone), figure out the BPM of a song on the fly, and find a convenient reference to the BPM ranges of common tempos. It is available completely free on the App Store, and if you really like it, there is a 99 cent in app purchase to support development you can make.
