FizziQ Web is a free web application that turns your computer into a science lab. It lets you analyze sounds and videos, use physics simulations, connect external sensors (FizziQ Connect, Arduino, micro:bit), and create complete scientific reports.

FizziQ Web supports students throughout their entire scientific process: Experiment (capture data), Analyze (organize and understand), and Share (communicate results).

Simply open your browser and go to fizziqweb.web.app. No installation is required, and no account needs to be created. The application loads directly in the browser.

Chrome or Edge are recommended to access all features, in particular the Bluetooth connection with FizziQ Connect and the USB connection with Arduino/micro:bit.

Firefox and Safari support audio analysis, video analysis, and simulations, but not Bluetooth and USB connections.

Yes, FizziQ Web is entirely free. No subscription, no ads, no feature limitations. All features are available to everyone.

No, no account is required. Your data is stored locally in your browser. This is a privacy guarantee for student data.

Yes, perfectly. FizziQ Web is ideal for schools equipped with Chromebooks. It runs directly in the Chrome browser without any installation. All features are available, including the Bluetooth connection with FizziQ Connect.

No, all data stays on your computer. FizziQ Web does not send any data to external servers. Files are stored locally in the browser (localStorage). To keep your work, export it as a .fizziq file or as a PDF.

Click Settings in the left sidebar, then Language. FizziQ Web is available in 21 languages: French, English, Spanish, German, Portuguese, Italian, and many more.

FizziQ mobile uses the smartphone's built-in sensors (accelerometer, GPS, magnetometer, and so on). FizziQ Web does not have access to these sensors but offers:

• Advanced audio analysis (high-resolution spectrogram)
• Complete video analysis (motion tracking)
• Physics simulations (pendulum, spring, circuits, and so on)
• Report editor with LaTeX formulas
• Larger screen for analysis

The two applications are complementary and can exchange data via QR Code.

FizziQ Web requires an internet connection for the initial loading. Once loaded, some features can work offline, but staying connected is recommended for the best experience.

1. Click Experiment → Audio analysis
2. Allow access to the microphone if prompted
3. Choose the display mode: waveform, spectrum, or spectrogram
4. Press Record to capture the data

You can also import an existing audio file.

1. Click Experiment → Video analysis
2. Import a video from your computer
3. Set the scale using a known reference
4. Mark the position of the object frame by frame

FizziQ Web automatically calculates positions, velocities, and accelerations.

Click Experiment → Chronophotography, then import your image. You can also create a chronophotograph from a video using the Tools → Video chronophotography tool.

FizziQ Web offers 10 physics simulations:

• Pendulum: oscillations, period, damping
• Spring: harmonic oscillations
• Ballistics: projectile trajectory
• Inclined plane: motion with friction
• Centrifuge: centrifugal forces
• Electric circuit: RC, RL, RLC circuits
• Waves on a lake: propagation, interference
• Ideal gas: thermodynamics PV=nRT
• Optics: lenses and mirrors
• Three bodies: gravitation

All simulations generate usable data, just like a real experiment.

1. Use Chrome or Edge
2. Turn on your FizziQ Connect device
3. Click Experiment → External sensors
4. Click Bluetooth
5. Select your device from the list

The connected sensors appear automatically.

1. Program your microcontroller to send data in the format FZ0:sensor:value
2. Connect it via USB with a data cable
3. Close the Arduino/MakeCode IDE
4. Click Experiment → External sensors → USB Serial
5. Select the USB port

See the complete user guide for code examples.

Open your experiment notebook, click + → Data table. A blank table appears. Add columns (quantities), define the units, and enter your values.

Yes, this is a key feature of FizziQ Web. Whatever the source (audio analysis, video, external sensor, manual entry, or simulation), the data is in the same format and can be analyzed with the same tools (tables, graphs, formulas).

Open a data table in the notebook, then click the Graph tab. Select the columns for the X axis and the Y axis. You can display up to 5 curves at the same time and choose from 6 types of interpolation.

In a table, click + new quantity. Give the column a name and enter a formula starting with =. For example: =Distance/Time to calculate a speed.

FizziQ Web supports:

• Operators: +, -, *, /, ^ (power)
• Functions: sin, cos, tan, sqrt, ln, log, exp, abs
• Constants: pi, e
• Statistics: sum(), mean(), stddev()
• Differentiation: derivative(), derivative2()

Use the column names as variables: =0.5*mass*speed^2

In the Graph tab, click Interpolation and choose the type: linear, quadratic, exponential, sinusoidal, and so on. FizziQ Web automatically calculates the coefficients and displays the equation.

Yes! Go to Tools → Python. The built-in interpreter supports numpy and matplotlib. You can define Python functions and use them in table formulas.

Open the observation card in the notebook, click Export, then select CSV. The file can be opened in Excel, Google Sheets, or LibreOffice.

1. Enrich your notebook with text and photos
2. Click Edit the report
3. Add text, images, and formulas
4. Insert the notebook observations (tables and graphs)
5. Click Finalize

In the report editor, click the Σ button or type directly between dollar signs: $E = mc^2$. Useful examples:

• $\frac{a}{b}$ for a fraction
• $\sqrt{x}$ for a square root
• $x^2$ for an exponent
• $\Delta t$ for the delta symbol

Once the report is finalized, click Export to PDF or Export to Word. The file is downloaded to your computer. PDF is ideal for printing, and Word for later edits.

Export an observation as a QR Code. Open FizziQ on your smartphone and scan the QR code to retrieve the data. This is handy for transferring measurements between computer and phone.

Restricted mode lets you display only the tools needed for an activity:

1. Go to Settings → Customization
2. Enable Custom mode
3. Check only the useful tools (for example: Video analysis, Spreadsheet, Report)

Students only see these tools and are not distracted by the others.

After setting up restricted mode:

1. Click Generate a link
2. Copy the link
3. Share it with your students (email, LMS, QR code)

When students open the link, FizziQ Web automatically loads with your configuration. This is ideal for preparing a lab session.
