Про.ОК vs Power System Lab

Мобильное приложение «Про-ОК» создано для быстрого и удобного обучения на смартфоне или планшете. Здесь вы найдете полезные материалы, ключевые документы и стандарты, контакты, а также актуальные новости. Это возможность получать знания и доступ к важной информации в любое время и в любом месте в удобном электронном формате.

Power System Lab brings marine electrical learning, hands-on simulations and practical tools to cadets, electro-technical officers and anyone studying shipboard electrical systems on iPhone and iPad. Explore your learning island: follow explanations and activities, try virtual instruments and track your route. Change circuit parameters on virtual benches and compare the results. Investigate your training ship. Inspect marked components, collect findings and choose diagnostic actions. Work through repair and verification stages, explore equipment and prepare the vessel for a voyage. Four games bring variety to your practice: • Knowledge Tower: drop containers from a crane, keep the stack balanced and collect short facts. Compare your best runs in weekly and all-time player standings. There are no cash prizes. • Name the equipment: 250 photographs covering 45 types of equipment, components and tools. Choose one of four answers, learn its purpose, zoom into the image and revisit mistakes. Progress syncs with your account. • Match-three: component combinations, electrical effects and short facts about electricity and marine systems. • Crosswords: marine and electrical terms, new ports and grid zoom. Russian and English puzzles keep separate saved letters and progress. Keep useful tools within reach: electrical calculations, 4–20 mA signal scaling, Pt100/Pt1000, resistor markings, Modbus register conversion and more. Search, save favorites and check formulas. Set up clocks for your ship, home and ports. English and Russian interface. Native layouts adapt to iPad rotation. Choose a character and uniform, adjust effects and animations, or study with gentle surf and distant gulls. There are no ads. The tower leaderboard lets you hide another player or report their name. All users need a subscription for the main features after sign-in. If Apple confirms introductory-offer eligibility, either plan starts with 3 free days. You must confirm the subscription through Apple immediately; registration alone does not start a trial. Only one introductory offer is available per Apple Account for the subscription group. Switching plans or creating another Power System Lab account does not provide another trial. If ineligible, the paid period starts immediately. After the trial, the subscription automatically renews at US$4.99 per month or US$39.99 per year in the US storefront unless canceled in time. Both plans provide the same access; the year is charged upfront. Apple shows your localized price and terms before confirmation. To avoid the first charge, cancel through Apple at least 24 hours before the trial ends. Remaining free days after cancellation are not guaranteed. Internet is needed for sign-in, subscription verification, new learning actions and sync. In iOS, calculations and clocks run locally after access is verified; their settings and favorites sync when connected. The subscription also covers the website for the same account. Purchases are made only through Apple inside iOS; there is no separate web payment. Restore Purchases, subscription management, support, legal documents and account deletion remain available without a purchase. Restore with the original Apple Account and Power System Lab account. Deleting the app or account does not cancel an Apple subscription. Apple handles refunds; mandatory consumer rights are preserved. For independent study. The app does not replace formal training, equipment documentation or vessel procedures and does not provide professional certification.
