Unlock your brain and remember any number effortless !

Ginkgo Memory is a tool to help you build, learn and use an extremely powerful mnemonic system for numbers.

Sometimes, remembering a new phone is such a challenge ! Our brains are just not meant to remember numbers… But actually, you would be surprised how easy and entertaining it is if you use the right tool !

What tool ? A peg system ! It works by creating mental associations between objects and numbers. These associations have to be memorised one time and can then be applied repeatedly to remember any number.

With this method, memorising a few hundred digits of Pi is actually a piece of cake !

We want to give you full flexibility over your table so you can put your own pictures to represent numbers. To save you some time your table is initially pre-loaded with pictures following the Major system.

Allen’s Computer ,

Very well done app

I have been wanting to apply this memory technique since I read about it in Unlimited Memory. But like any skill you can develop, it requires some effort and practice. I didn’t want to put in the time to make a n Anki deck for my number pics. But this app has done most of the work for you! It uses spaced repetition which is the closed thing to a direct download into your brain that we have right now. The controls are intuitive and easy to use. There could be a little more explaination behind why the pictures match. Once I realized it was a peg system converting numbers to sounds it made sense. The pics are easy to change, though you do need them to be the right size or you’ll only see part of them, BUT over all, aside from a few pics the don’t resonate with me, it is a very well done app.

Preset representations aren’t obvious

Preset representations aren’t obvious, and I don’t know how they’re interpreting the picture with the number.

Are you guys at least able to give the reason for the numerical interpretation or at least assign them according to the major system?

Developer Response ,

In last update we changed all the pre-loaded pictures to Major system !
Maybe you want to give the APP another try ?
