HQR and HQz are Android phone apps useful to the student and practitioner of homoeopathy. There are demo videos for both the Apps on the Google Play Store, along with screenshots to help you understand and use them.
HQz (Homoeopathy Quiz) is a quiz program based on Allen's Keynotes. It gives you multiple choice answers for a keynote, then indicates the correct one after you have answered. Once you complete the questions, it displays any errors you might have made, along with the correct answers. This helps you study and revise. Then you can attempt a re-quiz of just the errors to ensure you have learned the keynotes. The number of questions asked per session can be modified in the settings.
When you read a keynote, two or more drugs may seem equally applicable. However, on reading the entire keynote carefully, you will usually find something in the keynote which is extra and distinctive. For example: "diarrhea - green mucus, like chopped spinach in flakes; turning green after remaining on diaper; after drinking; after eating candy or sugar". One might think of mag-c or cham for the first part of the keynote - and these would be options offered in the multiple choice. However, when you read "after candy or sugar", you know that only arg-nit covers the entire keynote.
HQR (Homeopathic Quick Reference) is a rapid reference for homoeopaths consisting of seven sections:
MedInfo is the same information that you find on this website, and Keynotes is the text used in the Quiz here.
The information in Pocket MM is different from the Materia Medica section on this website, and Pocket Rep is not the same as the repertory used in PhaseRep. HQR and this website are complementary - each providing useful information, with some overlap.
Within HQR, you will find that the Pocket MM works like a mini repertory, and the Pocket Rep works as a mini materia medica. Once again, the content in the Pocket MM and Pocket Rep are not the same, and used together, they "complete", or complement each other. When you further study the keynotes, you will find that the main features of at least the polychrests are well covered.
However, as must be evident from the name, these are just pocket reminders, not reference sources. Both the materia medica and the repertory have some characteristic symptoms / rubrics and are not a complete listing. So if you feel some important rubrics are missing, don't be surprised. They are. The choice of rubrics is an individual matter, and no doubt one might feel other rubrics should have been included.
Case Taking is a section to help the novice while taking the case. It serves as a reminder for experienced homeopaths to ensure, after the case taking process, that they have not omitted important questions.
Finally, there is a link on HQR to this website, to allow rapid access to PhaseRep etc.
