This is an international app made by Koreans for students. What I really liked about this : 1. Excellent automatic scheduling depending on the total workload 2. Tracks how long a student actually ends up studying total fraction of the week 3. Progress Check' can be used to check study progress based on the amount of material and time period 4.Study Trend Graph' shows weekly progress and average study time. 5. Study alarm' gets the student started with your study on the time you set. What I thought as poor execution : 1. It's international so the Google Play sales pitch is not that good. I felt this is an area international app makers can use some help to be honest. 2. It can be 'too granular' for the spontaneous types.
