According to book "You Can Have an Amazing Memory Learn Life" written by 8 times world memory champion:
1.) 20 minutes short bursts of study avoid the negative impact of the primacy and recency affects on your ability to retain information and recall it.
Such burst should be followed by 4-5 minutes break
2) Herman Ebbinghaus in 1885 emphasised that the MOST RAPID memory loss occurs within the first two hours of memorization.
Suggestions to your great app )
1) 20 minutes auto timer that starts somewhere on a screen (maybe notification area)
when you press "Study" button. When time run out it ask you whether to start 4-5 minute timer.
2) When grading the card for the first time
Grade 1 change to 0.1
(maybe the best would be to change the name of button to "Just Learned" so new users can use it on the nail with 2 hours first repeating)
When failed to remember a card
Minimal interval change to 0.09
Grade 1 change to 0.1
(as I understood, maybe more changes needed)
