Unit Gacha ! vs Origami Learn

◆ Learn Physics Units with a Fun Gacha System Physics Units Gacha lets you practice unit breakdown, unit conversions, and fundamental physical quantities through randomly generated problems. Just tap to get a new question and continue learning at your own pace. ◆ Covers Essential Physics Units Practice and review a wide range of physics units: Mechanics (force, energy, momentum, pressure) Electricity & magnetism (voltage, resistance, charge, field strength) Waves & thermodynamics Derived units SI base units & physical constants Designed for students who want to study physics through units. ◆ Focused Explanations Where Needed Some problems include short explanations that show how units are derived from formulas. ◆ Random Practice Questions are generated randomly, allowing you to encounter various unit patterns and practice repeatedly. ◆ Simple Learning Features In-app scratch paper Learning progress is saved locally, and can be synchronized to the cloud when you sign in. Suitable for both quick review and focused practice sessions. ◆ For High-School Physics & Introductory University Courses A learning app designed to support the study of physics units for exams and fundamental review. ◆ Free to Use (Optional Paid Content) Approximately 70 problems are available for free Additional problem sets are available as optional paid upgrades

Origami Learn is a folding simulator, not a picture book. Every one of the 959 steps in this app is real geometry. The paper on screen is a simulated sheet with layers and creases, so you can drag a fold half-way and hold it there, turn the sheet over to see which flap moves, and replay the same crease as many times as you like. Nothing here is a photograph or a video. That is why it can unstick you when a diagram in a book cannot. 148 MODELS, 122 FREE FOREVER 116 origami models, 9 modular pieces built from folded units, and 23 kirigami designs you fold and cut. Cranes, boxes, flowers, animals, insects, stars, snowflakes, and the traditional children's furniture set. Each one is a genuine traditional design, with the region it came from and the paper it wants. A COURSE, NOT A CATALOGUE Nine chapters take you from "what is a valley fold" to bird bases, reverse folds, modular units and open-and-pull. Twelve lessons and seven practice sets, each unlocking the models that use what you just learned. Search the whole path, switch to a chapter grid, or ask for just the next thing in each chapter. LEARN TO READ ORIGAMI BOOKS Beside the live paper, every step is also drawn the way an origami book draws it: the standard symbols, dashed valley and dash-dot mountain creases, and fold arrows anchored to the corner that actually travels. Learn these and the rest of origami literature opens up. BRING IT TO LIFE Finish a model and decorate it. Thirty-six vector stickers — eyes, mouths, whiskers, leaves, stars — in any colour, plus freehand drawing. Print it, share it as a picture, or keep it in your gallery. Twenty models can be set moving and saved as a looping GIF: the flapping bird flaps, the frog jumps, the tulip opens. FOLD WITH YOUR HANDS FULL Say "next", "back" or "again". Speech is recognised entirely on your device and no audio ever leaves it. Or let the app read each step aloud while you keep both hands on the paper. IPHONE, IPAD, MAC AND APPLE WATCH One purchase covers all four. On Apple Watch the Digital Crown becomes a fold scrubber: rotate to close the crease, feel a tap when it lands, and the step moves on by itself. Add a complication and the watch face puts you back at the step you left. Progress follows you between wrist, phone, tablet and desk. MAKE IT YOUR PAPER Choose the colour of both sides of the sheet, per model or everywhere, including a colour-blind-safe pair told apart by lightness rather than hue. Print true-size squares and grids from Paper Tools. Design your own snowflake in Snowflake Studio and watch the cuts mirror around the wedge. BUILT TO BE READ Full VoiceOver in the player, Dynamic Type throughout, Reduce Motion that swaps animation for clear before-and-after states, AA contrast, and Kids Mode that hides anything needing scissors. FIVE LANGUAGES, COMPLETELY English, Tiếng Việt, 日本語, Español and 简体中文 — not only the buttons, but every model name, every step instruction, every tip, lesson and glossary entry. Switch language in Settings and the whole app reloads in it. NO ADS. NO TRACKING. NO ACCOUNT. There is nothing to sign up for and nothing to collect. No analytics, no advertising, no third-party SDKs. Your progress and your photographs stay on your device, and the whole library works offline.
