Physics vs SignPiP

Step into physics and watch the invisible become visible. Our app transforms fundamental principles into immersive Augmented Reality scenes, showing how physics concepts work in real time. By rooting every idea in a vivid, spatial experience, we bridge the gap between theory and intuition and make physics instantly relatable. Engage, spark curiosity, retain more. Visualizing virtual objects from every angle in their real world boosts attention and long‑term understanding—perfect for visual and kinesthetic learners. Built‑in concept walkthroughs. Every augmented reality scene includes clear, step‑by‑step explanations—before, during, and after exploration—so students always understand the “why,” not just the “wow.” Flexible for every setting. Ideal for classroom demos, one‑on‑one tutoring, homeschooling, or independent study. Safer, cheaper than traditional labs. No glassware, electricity, or expensive apparatus—just an iPad or an iPhone. Schools cut equipment costs, and learners experiment risk‑free. Ready for Schoolwork. Deep integration lets teachers push augmented reality assignments straight to student devices, collect results, and track progress—all inside Apple Schoolwork. Learn anywhere. At school, at home, or on the go, physics travels with you—no giant lab benches required. Physics+ is a subscription service that grants access to the complete feature set.

SignPiP makes videos accessible to Deaf and hard-of-hearing viewers by adding a sign-language interpreter — right on screen. Paste a link to a lecture or talk you have the right to use, and SignPiP creates a new version of the video with a signing avatar in a picture-in-picture window. The speech is transcribed, translated into sign, and performed by an animated interpreter in the corner of the screen — so you can watch the original video and follow the signing at the same time. BUILT FOR LEARNING Lectures, tutorials, and talks are often spoken-only. SignPiP means Deaf and hard-of-hearing students no longer have to choose between watching the content and reading captions: the sign appears alongside the video, the way a live interpreter would. WHAT YOU CAN DO • Turn videos you have the right to use into sign-language picture-in-picture versions • Watch in Chinese Sign Language (CSL) or American Sign Language (ASL) — one is included free, chosen to match your device language; the second can be added with a one-time in-app purchase (not a subscription) • Choose where the interpreter sits and how transparent the overlay is • Save the signed video to your device • Review and correct the signing — fix a word and re-render for a more accurate result HOW IT WORKS SignPiP listens to the video's audio, writes out what is said, and drives a 3-D avatar to sign it. Everything is assembled into a single video you can play or download. Made with, and for, the Deaf and hard-of-hearing community — because everyone deserves the same access to video.
