Instead of an app or gadget that claims to jump-start your productivity, you should consider investing in a good paper planner. 

There’s plenty of research that shows how actually writing down your to-do list and schedule for the day, rather than typing it out on a laptop or your iPhone makes you feel more engaged in the task at hand. But also, once the year is complete, a physical planner becomes an artifact, a time capsule, if you will, of all those momentous happenings from that calendar year.  

It allows you to keep track of your different responsibilities, and schedule your time appropriately. to meet those responsibilities, including your study.

Every week plan out the work week you want, set weekly priorities/goals, break them down into daily tasks, and focus.
