Use the time variable t to animate formulas, combine multiple surfaces in one scene, and start from built-in examples such as waves, a pulsating sphere, a cylinder, and a Moebius strip.\n\nThe app includes a custom math keyboard, local function storage, color selection, surface grid controls, rotation sensitivity settings, and graph orientation controls.\n\nPrivacy and offline use:\n\nThe app does not request network access. It does not include ads, analytics, tracking SDKs, account sign-in, or external API calls. User-defined functions and settings are stored on the device. If Android system backup is enabled on the device, app data may be included in that backup by the operating system.\n","categories":["Graphics","Science & Education"]}
