Learn Mirpuri & Pothwari vs Vector Fields

Learn Mirpuri & Pothwari is a paid family-route companion for heritage speakers and relatives who want usable speech for real visits, not a generic phrasebook clone. A purchase is required to use this app. There is no free sample. Monthly Access is an auto-renewing subscription. Lifetime Unlock is a one-time In-App Purchase and does not renew. FAMILY ROUTE MAP Twenty family situations: greetings at the door, kinship, tea and meals, phone calls, Ramadan and Eid, cooking together, visiting the village, condolence visits, talking about yourself, and more. Shared high-utility speech comes first. Labelled differences appear only when a teaching pair is documented. SAME MOMENT, DIFFERENT VOICES Compare Mirpuri-labelled and Pothwari-labelled teaching forms for the same family situation without ranking either variety as purer. Communities use more than one name. Choose the label your family uses. LEARN THE WHY Word banks for numbers, days, family titles, food, and the home. Plain-English grammar notes, including Pahari-Pothwari features like the -saan future. A sounds guide for aspirated, retroflex, and nasal sounds. Every example has a practice voice. PRACTISE DAILY Listening and phrase quizzes, play-all dialogues with two voices, phrase search, and a daily streak. REGISTER, NOT A SCORE Each phrase card asks who you would say this to. Practice audio is a generated rehearsal voice bundled with the app and works offline; it is not a native-speaker studio recording. Optional local recording lets you replay your own take. There is no pronunciation score and no upload. ON DEVICE Goals, region notes, progress, and recordings stay on your iPhone or iPad. No account. No ads. No third-party analytics SDK. SUBSCRIPTIONS Payment is charged to your Apple ID at confirmation. Monthly Access renews automatically unless cancelled at least 24 hours before the period ends.

See a vector field standing in the room in front of you. Vector Fields turns any three-component vector field into arrows you can walk around. Type something like -y, x, 0 and it appears in augmented reality, drawn in the space in front of you at true scale. Built for anyone learning or teaching multivariable calculus, where the hardest part is often picturing what a field actually looks like. Rotation, divergence and flow stop being abstractions once you can lean in and look along an axis. WRITE ORDINARY MATH Expressions are ordinary notation, not code. Implicit multiplication works, so 2x, 3sin(y) and (x+1)(x-1) all parse. Powers use ^ and are right associative. Odd roots of negative numbers give real answers, so (-8)^(1/3) is -2 rather than an error. Supported throughout: sine, cosine, tangent and their reciprocals, inverse and hyperbolic forms, exp, natural and arbitrary-base logs, square and cube roots, hypot, floor, ceil, round, sign, min, max, clamp, mod, and radian/degree conversion. Constants pi, tau, e and phi are built in. MISTAKES ARE EXPLAINED, NOT PUNISHED An unknown function, a stray operator or the wrong argument count produces a plain-language explanation rather than a failure. Some slips are repaired automatically and reported: a missing closing parenthesis is inserted where it belongs, parentheses wrapped around a whole field are removed, and commas inside a function call are no longer mistaken for component separators. SEE IT THE WAY YOU WANT Arrow length tracks the magnitude of the vector at each point, and a slider scales every arrow at once. A second slider sets thickness. Both update the field as you drag. MOVE THE ORIGIN Print ArUco marker ID 0 from the 6x6 dictionary at 100 mm wide (https://chev.me/arucogen/ generates it) and point the camera at it to move the world origin, and with it the grid and every arrow, onto the marker. Useful for putting the field on a desk in front of a class rather than wherever you happened to be standing. People occlusion is supported on devices that offer it, so someone walking through the field is drawn in front of the arrows instead of behind them. Requires an iPhone or iPad with ARKit support. No account, no ads, no tracking and no internet connection needed. Nothing you type ever leaves your device.
