Use any AI tool. Submit a working link or file for each task. Task 1: Build from a spec (15 pts, 10 min) Build a tip calculator with a bill input, 10/15/20% buttons, and a split-between-people stepper. It must work on a phone. Task 2: Logic and state (20 pts, 15 min) Build a Pomodoro timer with start, pause, reset, a 25/5 minute cycle, and a session counter. It must stay accurate if the tab is in the background. Task 3: Ambiguity (15 pts, 10 min) "Make me a habit tracker." You get no other details. Write down your assumptions, then build it. Task 4: Data and persistence (20 pts, 20 min) Build an expense tracker with categories, a pie chart, a month filter, and data that is saved between visits. Handle empty, zero, negative, and huge amounts. Task 5: Iterate without breaking (20 pts, 15 min) On your Task 4 app, make these changes in order: (1) add dark mode; (2) add edit and delete; (3) add CSV export. Nothing that worked before may break. Task 6: Debug and review (10 pts, 20 min) You will be given a buggy app with 5 planted bugs. Find and fix as many as you can, and explain each one in one sentence.
