Now RemNote uses SM-2 as its best algorithm, which is quite out-dated as SuperMemo already uses SM-18.
The SM-2 can’t adjust intervals based on the difference between your actual review time and supposed revew time(you may not always finish all the cards on time, so that creates a delay time) and have many other problems that may increase your daily workload which may considered as unnecessary using SM-18.
I’ll appreciate you can listen to my advice and I hope RemNote to be better from the bottom of my heart.
