How loud is your bike, really?

Not what the brochure claimed. Not what your mate reckons. The number, off your own phone, in about ten seconds.

Rev Meter showing a live decibel reading

One number hides what happened.

Most meters hand you a single figure and let you draw your own conclusions. A run has a shape. The quiet before it, what it settled at, and the moment it peaked are three different facts, and only one of them gets you pulled over.

Your limit is not a round number.

It is written down, it differs by country, and in India it changes with your engine size. The figure for a 100cc commuter is not the figure for a 500cc twin, and the officer with the meter knows which one applies.

Rev Meter knows too. It tells you if you are over, and by how much.

A finished measurement showing minimum, average and peak

It will not flatter you.

A phone microphone is not a laboratory instrument, and we are not going to pretend otherwise. Rev Meter states its margin on every screen: plus or minus 3 to 5 decibels after calibration, and not a legal instrument.

Anyone promising better accuracy from the same hardware is selling you something. We would rather you trusted the number we do give you.

The session log, showing past measurements kept on the phone

There is more in it than this page shows.

That is on purpose. A few of the things we have not explained here:

What happens when the microphone clips, and why it tells you
How one quiet room makes every later reading better
Why the loudest millisecond is deliberately ignored
What the app keeps, and where it keeps it
Ride with it for a week and you will find the rest.

Getting hold of it.

Rev Meter is in closed testing on Google Play. A small group of riders has it, and the list is not open to everyone yet. Free when it lands. No ads, no tracking, no account, and it works with your phone in flight mode.
