About

Engine Calc

Features
Read full description

Engine Calculators is a technical tool designed for marine engineers and engine room personnel. The application includes a set of calculators frequently used in shipboard operations for fuel management, engine performance, and unit conversion. Included calculators: - Oil Calculator Manual and automatic calculation of oil quantities on board. Allows setup of tanks and tank tables for fast and accurate results by tank. - Main Engine Power Calculator Calculates main engine power output based on entered engine parameters. - Slip Calculator Calculates the slip of the ship’s propeller — the difference between the theoretical speed (if the propeller were moving through a solid medium) and the actual vessel speed. - Unit Converter Converts values across various engineering and maritime units, including stowage factor, volume, length, speed, and temperature. Features: - Works fully offline, suitable for use in engine rooms and at sea. - Google Drive backup available for Oil Calculator data, allowing easy recovery on a different device. - Supports both light and dark themes. - Focused interface with clear input/output for practical use during daily operations. The app is built to support daily tasks related to fuel monitoring, power estimation, and performance tracking aboard marine vessels. All tools are designed for quick access and reliability in real-world shipboard conditions

Verdict

The call

The clearest difference is price: Arduino Programming Tutorial at Free against Engine Calc's $24.99. Arduino Programming Tutorial also leads on update cadence (every 6 weeks vs every 3 months). Engine Calc's advantage is ads (none vs shown) and iOS requirement (14.0 vs 16.0). On in-app purchases and device support there is nothing between them.
