Eng Fluids
Read full descriptionHide full description
Eng Fluids app provides real homework and test problems for the common engineering course called Statics. 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 ($2.99) has over 250 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 clearest difference is in-app purchases: Eng Fluids at none against Mechanical Formula's 1. Eng Fluids also leads on iOS requirement (9.0 vs 13.0). Mechanical Formula's advantage is update cadence (every 4 months vs every 13 months). On price, ads and device support there is nothing between them.
