I have a plan to develop a new android education app, among these three mobile application ideas which one of the ideas do you like the most.

1. General Engineering Calculator
It will cover most of the formulas and calculations in Electrical, Civil, Chemical and Mechanical Engineering.

2. Plant and Human Anatomy in 3D
It focuses on plant and human anatomy in 3D with some additional features.

3. Students Course Planner
It will work as a utility app that helps students plan everything around their studies. It will also incorporate time management system and other additional features
