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 review sentiment: phyphox at 79% against Gradiently's 50%. phyphox also leads on ratings volume (272 vs 3) and iOS requirement (12.0 vs 18.5). Gradiently's advantage is rating (5.0 vs 4.6). On price, update cadence, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Gradiently holds the better App Store score, 5.0 against 4.6. 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 complicate that: 50% of Gradiently's written reviews are positive against 79% of phyphox's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Gradiently ships an update every 5 months, phyphox every 3 months. The most recent releases landed on June 3, 2026 and September 24, 2026 respectively.
