Lumi Quest vs Python, Step by Step

Lumi Quest turns cities into courses. Most travel apps optimize for sightseeing. Lumi is built for the people who travel to learn — students on a semester abroad, researchers between conferences, designers chasing studios, lifelong learners who pick a city because something there is worth understanding. Tell Lumi what you want to learn — AI, architecture, philosophy, food science, contemporary art, urban planning, anything — and Lumi turns the city around you into a structured study route. Every stop is chosen to deepen what you came to learn, not to fill a checklist. HOW LUMI HELPS YOU LEARN • Curiosity-driven study routes Type a city and a topic. Lumi streams a multi-day learning route: activities, places, why each one matters, and questions to think about along the way. Each day comes with learning objectives and reflection prompts — so you arrive at every stop knowing why you're there. • On-site translation, when learning needs language Speak or type in English, Chinese, Japanese, Korean, French, or German. Lumi translates instantly and saves the phrases you actually use, so every conversation with a curator, a professor, or a stranger at a café becomes part of your study notes. • Visual learning Point your camera at a plaque, an exhibit, a building, a manuscript. Ask Lumi what you're looking at. Get the context, the period, the significance — in your language, in seconds. • Field notes that become a study report Every conversation, every translation, every photo question is part of your learning record. After each trip, Lumi turns it all into a structured study report: discoveries, daily highlights, connections across topics, questions you still want to answer. • A library of journeys Every city you study is saved on your device. Come back to your Tokyo AI route a year later and pick up where you left off. Compare what you learned in Berlin to what you noticed in Kyoto. WHO LUMI IS FOR Lumi adapts to how you learn. • Students — campus-rich, budget-aware, curiosity-first study routes. • Researchers and professionals — labs, archives, talks, networking. • Creators — studios, residencies, design districts, maker spaces. • Lifelong learners — expert access, deep context, intellectual range. PRIVACY BUILT IN No accounts. No tracking SDKs. No ads. No data brokers. Your study routes, translations, and reflections live on your iPhone, in Apple's secure on-device store. AI runs only when you ask it to. Wipe everything in one tap from Settings. LANGUAGES English, Chinese (Simplified), Japanese, Korean, French, German. WHY LUMI EXISTS The best learning happens in the world, not on a screen. Lumi brings just enough AI to make the world legible — so the curiosity stays yours.

A quiz-based Python learning app, sized for your phone. Python, Step by Step is a Python intro built for people learning to code for the first time. Tap-only micro-lessons that take a few minutes each cover the basics — variables, data types, branching, loops, functions — without ever asking you to type a single line of code. Highlights - A few minutes per lesson. Built for your commute, your coffee break, your before-bed reading - 16 units — from the basics all the way to classes, exceptions, and the standard library - Varied exercises — predicting output, filling in blanks, reordering lines, and more - All learning content is free. No paywalls - Streaks (consecutive days) help you build the habit Who it's for - People just starting with programming - Anyone who needs to pick up Python for work or a career switch - Anyone who wants to touch a bit of code in short bursts What you'll learn (16 units) 1. Welcome (first program, print, comments, input) 2. Variables and Data Types (numbers, strings, booleans) 3. Doing Math (operators, f-strings) 4. Branching (if / elif / else, logical operators) 5. Repeating (for / while, break / continue) 6. Functions (defining, arguments, return) 7. Talk to your program (input, prompts, interactive programs) 8. Group with lists (create, index, loop) 9. Dictionaries and tuples (keys and values, sets) 10. Classes 101 (__init__, self, methods) 11. Exceptions (try / except, raise) 12. Files (open, read, write) 13. Functions, leveled up (lambda, *args, map / filter) 14. Class inheritance (super, overriding) 15. Comprehensions and iterators (generators, yield) 16. Standard library (math, random, datetime, os)
