Physics Class by Haloa
Circuits, optics & mechanics
Free · In‑App Purchases
iPad
Light a bulb, balance a lever, and explore convex lenses in three complete free experiments. Record, save, reopen, and export PNGs. More activities require membership.
Explore virtual physics experiments on your iPad. Build circuits, balance a lever, or move a convex lens, then see how changing a condition changes the result. Physics Class brings hands-on simulations, guided activities, and measurement records together.
Three complete experiments, free
No membership is needed for the three included activities: lighting your first bulb, restoring a lever to balance, and freely exploring convex-lens imaging. Operate, record, save, reopen, duplicate, and export PNG images in these activities, with no trial timer or attempt limit. The free access applies to these three specific activities; other related lessons and separately created freeform experiments require membership.
Circuits, optics, mechanics, and more
Explore 50 experiment topics across measurement and motion, forces and pressure, machines and energy, sound, light, heat, circuits, and electromagnetism. Investigate current, voltage, Ohm's law, lens imaging, lever balance, and buoyancy. Connect circuit components or change conditions using each experiment's controls, then compare the model's results.
Measure, record, and compare
Follow activity guidance to make predictions, change conditions, record observations, and add notes and conclusions. Some electrical experiments include instrument readings and charts for comparing measurements. Save progress on your device and return to it later, or export a PNG image of your experiment.
Free access and membership
The remaining lessons, challenges, and separately created freeform experiments require membership. Choose a monthly auto-renewing subscription or a one-time lifetime purchase; both unlock the full membership content. Prices, eligible offers, and renewal terms appear on Apple's purchase screen. Restore purchases in the app and manage subscriptions through Apple.
If membership expires, existing experiment work remains available to view and export as PNG images and is not automatically deleted. Editing, saving, and duplicating paid activities require an active membership. The three free experiments remain available to operate and save.
Learn on your device
Built-in lessons and experiment calculations run on your iPad. No separate app account is required. Experiment data stays on your device and is not automatically uploaded to the developer. Loading product information, purchasing, and restoring purchases may require an internet connection.
Experiments use simplified physical models. Results depend on each model's assumptions and settings. The app does not replace safety guidance for real-world experiments.
