Kardiograph

Kardiograph is an app for people who want a simple way to keep track of heart-related measurements on a phone. Its real strength is the plainness of that job: it belongs to Health & Fitness, and that usually means quick reading, logging, or following a personal routine rather than formal care. By our assessment, the honest downside is the obvious one for any consumer heart app — it can support awareness, but it cannot stand in for proper medical equipment or a clinician. In practice these apps tend to feel clinical and a little repetitive, which is useful when you want structure and tiring when you do not. Kardiograph sits below specialist devices and above a handwritten note, which is exactly the narrow place such apps occupy. It is for people who like keeping an eye on patterns and not for anyone looking for diagnosis from a phone screen.
