This is a lite version of the full paid app. But you can still find a lot of new and interesting things in it. In this app you will be able to see what the epaulettes and insignia of merchant seafarers look like in different countries. You will learn about the job hierarchy on different types of ships, who reports to whom, and what the job responsibilities are for different crew members. Some ship types and seafarer positions will be blocked, but for your convenience you can easily go to the full app page, and purchase it, hopefully you will be interested.

Binary Lab is the toolkit serious traders keep next to their platform. It is not a broker and executes no real trades โ it's where you learn, plan and review so your real decisions get sharper. THEORY QUIZZES ON A LIVE-FEELING MARKET A realistic feed with candlestick charts, 12 assets, four timeframes and questions. Test your ideas. KNOW YOUR REAL NUMBERS The journal turns your trades into answers: win rate, equity curve, profit factor, streaks, best weekdays, best setups โ and which emotional states cost you money. Export everything as CSV. RESPECT THE MATH Break-even win rate, position sizing, compounding projections, risk of ruin, and a martingale planner that shows the true bill before the market does. A risk manager with daily limits and a pre-trade checklist keeps discipline visible. LEARN THE CRAFT 10 strategy guides, 14 candlestick patterns with diagrams, a trading psychology library, a 60-term glossary and a knowledge quiz. PRIVATE BY DESIGN No account, no ads, no tracking. Everything stays on your device. โ Binary Lab is an educational utility. Binary options carry a high risk of loss; most retail traders lose money, and retail sale is restricted or banned in some jurisdictions. Nothing in this app is financial advice.
