Features & Capabilities

Tachometer - RPM Measuring is a powerful Chrome extension designed to accurately measure and save the revolutions per minute (RPM) of rotary devices such as turntables, record players, and motors. Utilizing your phone's IMU sensor, the app calculates both instant and average RPM values, providing a simple and efficient way to calibrate motors and control rotary speed.

The extension features a user-friendly interface equipped with a real-time visualizer for RPM data. Users can start and stop RPM recordings easily, with all measurement data saved in a convenient CSV format for analysis or record-keeping. This tool is ideal for audiophiles, technicians, and hobbyists looking to accurately monitor rotary device speeds without bulky equipment.

Key features include instant RPM readings, average RPM calculation, data recording with timestamping, and easy access to saved data. Its accuracy depends on the sensor quality of your device, making it a versatile and accessible solution for various RPM measurement needs.

User Reviews

Most reviews condemn the app for intrusive ads and unreliability, reporting inaccurate or random RPM readings and limited applicability to real-world engines. A couple of users note it can measure the phone's RPM and even verify RPM after maintenance in rare cases, but the overall sentiment is that the app is largely unusable for its intended purpose. Camera access problems and closing bugs are also mentioned, reinforcing a perception of poor usability.

Pros

It can measure RPM on the phone, and in some cases seems to work as intended.
In at least one review, it helped verify RPM after maintenance (e.g., 33 rpm).
Some users found it usable for certain tasks.

Cons

Intrusive fullscreen ads; ads everywhere.
Not working properly, unreliable, and often produces random or inaccurate RPM readings.
Not applicable to small engines or general-use cases; limited applicability.
Camera feature is not usable or cannot view the object image.
Bugs or usability issues like slow performance and difficulty closing the app.
