I have learnt to memorize a deck of cards and decks of red/black cards (binaries). The binaries are pretty fast now, but the cards themselves are still slow. I wanted to practice daily and keep track of my progress by measuring how fast I do the memorizing part and how fast I do the recall part.

I measured the time with stopwatch, clicking “lap” between memorization and recall and then “stop”. I get two times.

I am looking for an app that would store each of my attempts with date and could show graph with days at the X-axis and times at Y-axis and that would show my best times yet.

I would like to be able to do measurements for different activities (remembering random digits, deck of cards, etc.).

I believe there must be something for this - just measuring times and keeping track of history of measurements to show on graph - but I find it difficult to find something. Do you guys know of anything?

Thanks!
