RatesBook
Read full descriptionHide full description
Based on the approximately 10,000 classic Copen rates for "Organs and Symptoms" and "Homoeopathic Rates Listing", the "Rates book" app includes all rates from the digital Copen devices MARS III and Scope Q. This means that users of their classic Copen device have over 60,000 rates (!) at their disposal. Simple search functions make the app easy to use and allows you to find rates in just a few moments. The displayed rates must then be manually transferred to the respective Copen device. So you get the best of both worlds for your Copen MK or ASLD - according to the motto: Back to the future! :-)

Verdict
The clearest difference is price: Gunalight at Free against RatesBook's $79.99. Gunalight also leads on update cadence (every 3 weeks vs every 2 months) and iOS requirement (11.0 vs 15.0). On ads, in-app purchases and device support there is nothing between them.
