Released the "S Metronome" app

We released S Metronome, an app that calculates playing time from the time signature, tempo, and number of measures, and also works as an advanced metronome for mixed meter practice.

What kind of app is it?

This app automatically calculates playing time from the time signature, tempo, and number of measures. It was born from a very practical need: in concert band settings, there were moments when we wanted to know how many seconds would be saved by cutting certain passages from a score.

Back then, that meant using a pen and a calculator. We thought it would be much easier if an app could handle it, and that is what led to the development of S Metronome. It was originally created to help with cut planning for contests and ensemble performances, but it can also be useful in many other situations.

Based on the data you enter for playing time calculation, the app also provides a metronome function that can handle mixed meter and section-by-section tempo changes. There is no complicated setup. Just set the time signature, tempo, measure count, and reference note value when needed, and the metronome responds flexibly.

With this app, even contemporary pieces with constantly changing meter and pops medleys with repeated tempo changes can be practiced individually before rehearsal.

Released versions and planned updates

Already released

  • ver1.0: Playing time calculation
  • ver2.0: Added the metronome function and ads to the free version
  • ver2.1: Added off-beat options for triplets and 16th notes, plus multi-language support

Planned next

  • ver3.0: Tuner support and handling for tempo changes such as accel.
  • ver3.1: Tap tempo and improved metronome sounds
  • Ongoing: Android release
These plans are still plans. The order may change, and we may also build new ideas that come to us along the way.

What we want to work on first

The highest priorities right now are an Android release and better support for tempo changes. The Android version requires a certain amount of cost and a lengthy review process, often 14 days or more.

Tempo-change support is technically within reach, but the design that fits the current app has not fully come together yet, so it has been postponed for now. If we want to honestly say that this app helps you practice through an entire piece, that feature matters a lot.

Feedback is welcome

Because this is our first app release, there may still be unexpected bugs. If there is a feature you would like to see, an app you wish existed, or a problem you are dealing with, we would love to hear from you.

Your feedback will help shape future app development.
