Stuck on a statistics or math problem and the answer key only shows the final number? This app works the problem the way a tutor would: one step at a time, with the reasoning written out, so you can follow it and reproduce it on the exam. Most homework helpers hand you an answer and leave. Here the solution stays with you — saved, searchable, and backed by exact calculators that run on your iPhone. The mean, standard deviation, quartiles, determinant or binomial probability is computed by the app itself, not guessed, so you can check the AI's work against real math instead of taking it on faith. WHAT YOU GET - The full worked solution, step by step, instead of a bare final answer - A photo of a problem read on your device by text recognition, then solved - Follow-up questions answered by an AI tutor until the confusing step clicks - Your own answer checked before you hand it in, with an explanation of what went wrong - Four calculators in one place: scientific, statistics summary, probability distributions and matrix - Recall that lasts: spaced-repetition flashcards, quizzes, cheat sheets, formula topics and a study streak PERFECT FOR - Stats 101 students facing a problem set the night before it is due - Nursing, psychology, business and economics majors who need statistics, not a math degree - Adults returning to calculus, algebra or probability after years away - Self-taught learners revising for an exam with no tutor on call WHY NOT JUST ASK A GENERAL CHATBOT? A chatbot gives you one wall of text that disappears when you close the tab, and it is happy to invent a number. This app splits the answer into labelled steps, keeps every solution in a searchable history you can bookmark, lets you ask follow-ups in context, and computes descriptive statistics, distributions and matrices with real formulas on device — so the arithmetic is not a guess. PRIVACY No account, no ads, no tracking. Photo text recognition runs entirely on your device. Your history, bookmarks, flashcards and datasets stay on your iPhone. AI solving and tutor chat connect to OpenAI using your own API key, which you paste once in Settings and which is stored on your device only. FULL ACCESS Full access unlocks unlimited AI solving, photo input, the AI tutor chat, answer verification, the statistics, distribution and matrix calculators, data import with histogram, scatter, box plot and normal-curve charts, practice quizzes and every flashcard deck. Available as a weekly subscription, a yearly subscription, or a one-time lifetime purchase. The scientific calculator, cheat sheets and formula topics are included either way. Open the app, type in the problem you are stuck on right now, and read the first step.
