From the data gathered, we were able confirm well-known results on mental arithmetic (Figures 2, 3 and 5)  as well as to observe some new very interesting facts (Figures 4 and 6). Strong users were also able to learn how to square 3 and even 4 digit numbers in under one month of use, leading us to challenge the common definition of ?arithmetic prodigy?. Response time results suggest that  complex arithmetic calculations are solved as a series of simple steps. The fact that we could reproduce in two-weeks of data-gathering the main results that took years of laboratory work shows the potential of smartphones-based collaborative researches.
