★★★★★ as an engineering student this app has been exceptionally useful.
★★★★★ Useful tool but can be improved
★★★★★ I've been a mechanical engineer for 20 years and this app is extremely helpful...absolutely worth the $5
Looks great4%

4 of the 4 and 5 star reviews.

★★★★★ kindly update the application in All aspects like the material chapter is not that much effective, some New content about thread , mechanical design, machine related to be updated
★★★★★ Please consider UI scaling, so that everything isn't bunched up at the top and very small.
★★★★★ The only downside I would see is the fact that such a complete and wonderful app has in some parts a rather poor interface (in terms of looks), it seems to be incredible useful and organized, keep it up¡, five stars no…
