About

Physics Toolbox Tone Generator

Generate continuous tones with adjustable frequency and amplitude. Modify wave shapes like sine, square, triangle, and sawtooth. Useful for science education experiments and demonstrating sound wave principles.

Highlights
  • Continuous tone generation
  • Adjustable frequency (0-20,000 Hz)
  • Adjustable amplitude (volume)
  • Multiple wave shapes (sine, square, triangle, sawtooth)
  • Educational applications for sound science
  • Demonstrate inverse-square law
Features
Read full description

This tone generator app produces a continuous tone. The user can modify both the frequency (~pitch) (0 - 20,000 Hz) and the amplitude (~volume) of the sound wave. The wave shape can also be modified as sin, square, triangle, and saw-tooth. This app can be used in science education in conjunction with a sound meter to determine the inverse-square law for sound intensity, or with another tone generator to produce audible beats (by combining two tones of slight different frequencies). If you have any questions, comments, or would like to see modifications/updates, please email me at support@vieyrasoftware.net

Did you know that you are carrying a 3D magnetometer? That you can use your phone as a pendulum to measure earth's local gravitational acceleration? That you can turn your phone into a sonar? phyphox gives you access to the sensors of your phone either directly or through ready-to-play experiments which analyze your data and let you export raw data along with the results for further analysis. You can even define your own experiments on phyphox.org and share them with colleagues, students and friends. Selected Features: • A selection of pre-defined experiments. Just press play to start. • Export your data to a range of widely used formats • Remote-control your experiment through a web interface from any PC on the same network as your phone. No need to install anything on those PCs - all you need is a modern web browser. • Define your own experiments by selecting sensor inputs, defining analysis steps and creating views as an interface using our web-editor (http://phyphox.org/editor). The analysis consists of just adding two values or using advanced methods like Fourier transforms and crosscorrelation. We offer a whole toolbox of analysis functions. Sensors supported: • Accelerometer • Magnetometer • Gyroscope • Pressure • Microphone • Proximity • GPS • Camera • LiDAR/ToF *some sensors are not present on every phone. Export formats • CSV (Comma separated values) • TSV (Tab-separated values) • Excel (if you need other formats, please let us know) This app has been developed at the 2nd Institute of Physics A at the RWTH Aachen University.

Verdict

The call

The clearest difference is rating: phyphox at 4.6 against Physics Toolbox Tone Generator's 3.7. phyphox also leads on review sentiment (79% vs 40%) and ratings volume (272 vs 3). Physics Toolbox Tone Generator's advantage is iOS requirement (10.0 vs 12.0). On price, update cadence, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

phyphox holds the better App Store score, 4.6 against 3.7. That said, the two scores are not equally well evidenced: phyphox has 272 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 40% of Physics Toolbox Tone Generator's written reviews are positive against 79% of phyphox's.

UpkeepUpdate frequency

Physics Toolbox Tone Generator ships an update every 5 months, phyphox every 3 months. The most recent releases landed on September 7, 2026 and September 24, 2026 respectively.
