Mnemo Major System 4+

The Major System is an effective method for encoding numbers into images. Using this mnemonic technique, remembering a sequence of numbers is highly improved compared to simple memorization.
(Synonyms: Major System, Master System, Digit Code according to Aimée Paris, Phonetic System, conversione fonetica etc.).

Mnemo Major System allows you to create a personalised Major System for the mnemonics Major System.
With the help of the integrated training programme - the trainer - the Major System can be quickly learned and further optimised.
For this purpose, a traffic light system of reaction times to queried terms is used, which effectively exposes sub-optimally selected images and allows rapid optimisation in the development of one's own Major System.
A summary overview of the reaction times - here called statistics - additionally supports this process.
In addition to the master system, trainer and statistics, the generator was added as a further component, which enables the translation of arbitrarily long numerical sequences into the images of the major system.

To further facilitate the process of creating your own major system, a ready-made major system for the number range 00 - 99 has been integrated.
In addition, a list of alternative terms that satisfy the rules of the major system was added to each term.
Attention: The selected images are to be understood as examples and logically cannot be the optimal memory image for everyone.
(In ancient times, for example, teachers of mnemonics refrained from giving their students ready-made mnemonic systems. The students were supposed to develop their own systems. Even then, it was known that one's own associations facilitate memorisation).



• Multiple training possibilities
• Question mode for images or numbers
• Training with major system terms instead of pictures
• Free selection of the number range to be learned with optional restrictions to specific reaction time ranges, questions answered incorrectly or not yet processed terms
• Training level indicator


• Major System Terms and selected images for the numbers 0 – 99 and 00 – 09
• Major System Terms for the numbers 000 – 999
• Freely customizable
• Comprehensive collection of alternative Major System Terms
• Choice of alternative images (camera, photo album, integrated web search for images)
• Color codes for response times in the main view of the Major System
• Cards view (comfortable learning like using file cards)
• Optional extension to the three-digit major system (the trainer and the generator automatically use the chosen system: 2 or 3 digits)
• Build optional major systems (in addition to the German, English and Italian Major System three custom major systems can be build)
• CSV Import and Export
• Import and export (incl. pictures) in Mnemo file format


• Major System encoding for any numerical sequence
• Possibility of adding notes
• Saves any number of encodings
