| Subject | Copen RemedyMaster | ResoField |
|---|---|---|
| Product type | An iPhone and iPad app from Bruce Copen Laboratories in Gauting near Munich, used with a small coil that plugs into the device. The RemedyMaster was the first version. Since December 2015 the App Store has carried its successor, RemedyPro, which works with the RemedyPrinter coil. Copen calls it a digital pocket pharmacy that simulates homeopathic remedies, nosodes and other energetic preparations. | Browser application for reference libraries, client profiles, custom lists, protocols and planning. |
| Price | On 23 October 2026 brucecopen.com listed the RemedyPro with RemedyPrinter at 3,500 dollars. The German dealer Blum asks 4,380 euros including 19% VAT, delivered without a tablet, and 298 euros for an extra RemedyPrinter. The app is free in the App Store but does nothing without the paid hardware, and you bring your own iPhone or iPad. For the older RemedyMaster, the Dutch skeptics' foundation Skepsis gives 3,500 euros without the iPhone, with no date. | Free at the time of this review. |
| Output and workflow | According to Copen, the coil records the information pattern of a substance placed on it, and the app stores it. A stored pattern can be set to another potency and imprinted onto a carrier such as empty globules or memory cards. Copen also sells it as a digital test kit for kinesiology, RAC or a biotensor. The RemedyPrinter is 6 cm across and plugs into the headphone jack, or into an adapter on newer devices. | No audio, electrical current, PEMF or other physical device signal. |
| Capacity and customisation | Copen lists more than 60,000 test and therapy frequencies, among them organs, teeth, TCM, homeopathy, drainage, nosodes, products of pharmaceutical makers and flower essences. You can add your own entries. One licence covers up to three iOS devices, and the app is in English, German and Spanish. The current version, 4.8 from 24 March 2026, needs iOS 16 or later. | Custom lists and protocols are available. The new app allows up to 20 active plans per account and up to 6 scheduled rounds at the same time. |
| Banerji protocols | No built in Banerji library was found in the public product information reviewed. | Custom protocols are available. The built in Banerji reference library covers 433 conditions and 1,839 protocol lines. |
| Evidence and limits | Copen's own disclaimer says conventional medicine has neither accepted nor recognised quantum and information medicine, and that its QuantumResponse technology has no assured scientific proof of effect. A PubMed search on 23 October 2026 found no study on RemedyMaster, RemedyPro or Bruce Copen devices. The closest test we found concerns a related claim: in 2006 a team working at the request of the US defence research agency DARPA tried to show that a digitally recorded signal of a substance has a biological effect. Jacques Benveniste, who made that claim, took part. The team found no replicable effects. | ResoField is not a medical device and does not diagnose or treat disease. |

What this means in practice
The RemedyPro needs an iPhone or iPad, a coil and something to imprint, such as globules. ResoField needs none of that and makes nothing physical. You choose from almost 10,000 homeopathic remedies in the browser, set a potency from the D, C, M or LM series and broadcast it to a client, whose name and date of birth form the witness. If you work with a biotensor or muscle test, you test a list yourself and collect what fits in the test tray.
