Sunfox

Added on October 6, 2026

Sunfox began in 2016 as an R&D lab in Uttarakhand, and Spandan is what came out of it: a portable ECG that works with a phone app. The brand sells it for homes, for clinics and, in a separate ICU model, for critical care, and says the aim is clinical-grade care that is affordable.

The devices differ mostly in who they are for. Legacy 4.0 is the compact one at 14.5 grams with disposable electrodes, Neo adds a moisture-resistant IP55 build for home use, and Pro uses suction electrodes and is pitched at clinics. Sunfox says its traces match gold-standard ECG machines at 99.7% accuracy and that the devices are CDSCO approved. Those are the brand's claims, and its site has a clinical studies section for anyone who wants the detail.

Worth knowing: this is a medical device, so treat the accuracy and approval claims above as Sunfox's own rather than ours. Each device comes with five free doctor reviews and a 2-year warranty per the brand, and the store marks its prices as limited-time offers, so check the current price before you buy.

Best for: households that want an ECG at home, and small clinics after a portable one.
