Pocket Prep Clone

Build a polished native iOS clone of Pocket Prep in SwiftUI: an exam-prep app for the NCLEX-RN with a question bank by subject, Question of the Day and a streak calendar, eight quiz modes with instant right/wrong feedback and explanations, an AI Tutor, Review, Stats and spreadsheet import of questions.

It is Pocket Prep on screen: its name, its round blue "P" logo (drawn in SwiftUI), brand blue #1A6EEB, navy #253446, and its own words ("Good Evening", "All Studying", "QotD", "6 Day Streak", "Key: Studied / Exam Day", "Quiz Modes", "Question of the Day", "Quick 10 Quiz", "Timed Quiz", "Level Up", "Weakest Subject", "Missed Questions", "Build Your Own", "Mock Exam", "Question 5 / 10", "Show Explanation", "Hide Explanation", "Ask Tutor", "Answered Correctly", "Community", "Study Progress", "Subject Scores"). The student is Maya, studying for the NCLEX-RN.

SHELL
Tabs: Study, Review, Stats, Settings (blue selected). Opens on Study: no splash, onboarding, login, paywall or permission prompt.

SCREENS
1. Study: top row with the logo, "NCLEX-RN ⌄" and a white "Exam in 24 days" chip; a soft blue blob with halftone dots in the top right. "Good Evening" (Morning/Afternoon by time) and a quip. Tabs "All Studying | QotD" with a blue underline and "⚡ 6 Day Streak". A two-week calendar (last week + this week, S M T W T F S): studied days are navy filled circles joined by a navy line, today underlined, exam day a hollow ring; in QotD view, right answers are green filled and wrong ones red rings. Then "Quiz Modes": white bordered rows with a coloured icon, title and detail (QotD shows today's date and a blue dot until answered; Level Up shows "Level 2 · Management of Care"; Missed shows the count).
2. Quiz (full screen): navy backdrop, segmented progress (current segment yellow), a white sheet with X, "Question 1 / 10" (timer in Timed/Mock), flag. Subject caption, stem, four shuffled options in bordered boxes. Tap an option: the right one turns green with a check, a wrong pick red with an X, the rest fade; "Show Explanation ⌄" inside the right answer expands the explanation; "67% of Pocket Prep users got this right". Bottom: "Ask Tutor" and a blue "Next" / "Submit Quiz". Mock Exam and Build Your Own can hold answers until submit.
3. Results: navy header with an open green arc gauge and big %, "8 / 10 Answered Correctly", time; a "Next step" tip; every question with check or X, tap for the full explanation; Done.
4. Question of the Day: a dark navy card sheet with "Question of the Day", the date, the question in big white type, dark option rows, gold "Show Explanation" and a gold Done. Answering fills today on the calendar and grows the streak.
5. Tutor: dark chat sheet "Tutor  Question 1", starter chips ("Why is this the right answer?", "Explain it more simply", "Give me a memory trick"), a Reply field. Replies come from a real model: POST /api/tutor on the backend sends the question, choices, answer, explanation and chat to Claude (Sonnet) via the Vibecode proxy and returns a short explanation with an exam-day tip.
6. Review: "Review" with counts All / Flagged / Incorrect / Correct (big numbers, underline on the selected), "Search Questions" and a subject "Filter"; cards with subject, flag/check/X and the stem; tap for the question with your answer, the right answer, explanation and Ask Tutor.
7. Stats: navy header with the green arc gauge (overall %), black boxes "38 / 47 Answered Correctly" and "61% • Community"; collapsible "Study Progress • 78%" and "6 Subject Scores" (each % with "x / y Correct" and a green/orange/red bar); a "Quiz Scores" bar chart.
8. Build Your Own Quiz: Subjects menu "6 of 6", "When do you want to see the correct answer and explanation?" (After each question / After submitting quiz radios), Include New / Answered / Flagged / Incorrect with counts and checkboxes, "How many questions?" big number with − and +, Start Quiz.
9. Settings: logo card with "Premium", exam, exam date picker (drives the countdown and calendar), questions in bank, "Import Questions (CSV)" (pick a .csv or paste rows; columns subject, question, choice_a..d, correct A-D, explanation; preview then import; imported questions join every mode), Reset Progress.

DATA
60 original NCLEX-RN questions, 10 per subject: Management of Care, Safety and Infection Control, Pharmacological and Parenteral Therapies, Physiological Adaptation, Reduction of Risk Potential, Basic Care and Comfort; each with difficulty 1-3 and an explanation. SwiftData keeps every answer, flag and quiz. On first launch seed two weeks of history relative to today (a 6 day streak, ~45 answered, a few flags) and shift demo rows forward on later launches so nothing looks stale.
