Learn to read charts — with a pilot at your side. Chartlotse explains the basics of trading in plain language: candlestick charts, trends, support and resistance, breakouts, risk and the stop — no jargon, no pressure, no real money. YOUR WAY ABOARD • LESSONS: Short, understandable units with diagrams — from your first look at a candle all the way to patterns and risk management. • CHART TRAINING: Practise on freshly generated charts every time. Spot the trend, draw in your own entry and stop — with instant feedback and pilot's tips. • HARBOR STORIES: Short stories from everyday trading that show typical mistakes and mental traps — each with a quiz to make you think. • STRATEGY VOYAGES: Get to know complete approaches, step by step. • E-BOOKS: In-depth volumes to read at your own pace, right inside the app. • GLOSSARY: Tap any technical term and get it explained on the spot. AN APP THAT THINKS ALONG Chartlotse adapts to you: depending on how confidently you answer, the app offers to take you a level deeper or to ease off. Points, badges and your learning streak keep you on course. YOUR DATA STAYS WITH YOU No account, no sign-up, no ads, no tracking. Your progress is stored on your device only. The app works completely offline. TWO LANGUAGES German and English — switch at any time in the settings. Lessons, stories, glossary, e-books and training all change with it. IMPORTANT NOTE Chartlotse is purely a learning app. It offers no investment advice, no buy or sell recommendations and no trading with real money. Trading carries substantial risk of loss — always form your own judgement. Cast off — your pilot is waiting.

Verdict
The clearest difference is in-app purchases: Chartlotse at none against Octopus's 4. Chartlotse also leads on ads (none vs shown) and update cadence (weekly vs monthly). Octopus's advantage is iOS requirement (13.6 vs 15.1). On price and device support there is nothing between them.
