About

Eng Dynamics

This app offers practice problems and solutions for engineering Dynamics courses, mirroring textbook structures. It links to a free online eBook for theoretical support. A free version provides limited problems, while a paid version unlocks a comprehensive library.

Highlights
  • Real homework and test problems
  • Organized by textbook sections/chapters
  • Complete solutions with graphics
  • Links to online eBook theory
  • Extensive problem library (Pro version)
  • Problems used in real engineering classes

Read full description

'Eng Dynamics' app provides real homework and test problems for the common engineering course called Dynamics. All problems are organized in sections and chapters common to most textbooks. Each problem has a complete solution with graphics to help you better understand how to solve the problem. Also, each problem has a link to a theory web page for that section at the online eBook (eCoursesBook.com). There is no cost for the online eBook, and it can be accessed outside of the app. The 'Lite' version (free) of the app has a select number of problems, about 50-70. The 'Pro' version ($3.99) has over 400 problems. Neither has ads. Both versions use the internet to pull problems from an online database as needed. Network connection is required to run the app. Each problem is small (less than 20 k) and are vector-based graphics. All problems have been used in real engineering classes. Problems are accessed through an online database, so if any errors are identified, they will be updated and the app will use the corrected version. This program is copyrighted and cannot be distributed without the author's written consent.

Verdict

The call

The clearest difference is update cadence: AeroEngineS at every 3 days against Eng Dynamics's every 8 months. AeroEngineS also leads on monetization model (free vs freemium). Eng Dynamics's advantage is iOS requirement (9.0 vs 14.0). On price, rating, ratings volume and ads there is nothing between them.
