  •  – This functionality makes the Synthesis App a true companion to RadarOpus!
  •  – Concise Source Referencing


Synthesis is renowned as the repertory with the most reliable source referencing.

  •  – The Synthesis App does contain that same source referencing, be it in a concise format to save space on the screen.
  •  – The Synthesis App is slightly different compared to the RadarOpus software.
  •  – It does contain all remedies entries (all additions) and all rubrics, including some veterinary rubrics *, however it only contains one author reference per remedy.
  •  – If a remedy was present in Kent’s repertory you see a “k”.
  •  – If not, then the most original available reference is mentioned, starting from Hahnemann: “h”.
  •  – In fact, in the Synthesis App you can distinguish three categories of authors:

Classical sources: author abbreviations without any icon . This includes the Kent repertory, corrections on Kent’s repertory, all classical sources, and also more traditional contemporary sources and authors (until 1985)

Modern provings: author abbreviations with the ° icon. New remedy provings conducted in a classical method, and contemporary sources falling in this category

Hypothetical sources & meditation and dream provings: author abbreviations with the * icon

This is not a scientific division, but rather a pragmatic one for the Synthesis App.
To see more precise reference information regarding all additions in the repertory, we refer to the RadarOpus software. There you will be able to view all source references (the App only shows one author reference per addition). RadarOpus software allows the user full control over which sources are shown in the repertory at any given time (Repertory Views).
