Read full description

Eng Mechanics app provides real homework and test problems for the common engineering course called Mechanics of Materials, Deformable Bodies, or just Mechanics. 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 paid version ($3.99) has over 400 problems. There are no ads or in-app purchases. Network connection is required to run the app since all problems are pulled from an online database. 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.

Verdict

The call

The clearest difference is in-app purchases: Eng Mechanics at none against EnginPrep's 1. Eng Mechanics also leads on rating (4.8 vs 4.4) and review sentiment (75% vs 62%). EnginPrep's advantage is update cadence (every 3 weeks vs every 12 months) and ratings volume (192 vs 4). On price, ads, monetization model and device support there is nothing between them.
