Most health tools ask you to log how you feel, others require a wearable device or an in-person visit. Soma runs on devices you already have - first macOS and now iOS - to capture your voice as a health signal. By picking up on patterns in what you say and how you say it, Soma surfaces insights about your mental clarity, energy, stress, and more. HOW IT WORKS Soma runs primarily on macOS, capturing and analyzing your conversations as you go about your day. With the iOS app, you can now capture live conversations on the go and check your insights from anywhere. Soma builds your unique voice print to create a personalized understanding of you over time. - Personalized insights: specific, actionable observations drawn from your natural speech based on scientific evidence, not a one-size-fits-all cognitive assessment. - Voice print: Soma learns your baseline so insights get sharper and more personal the more you use it. - Context-aware: your speech carries rich context that helps us enhance your insights. You can also connect your calendar, location, Apple Health, and other health data so Soma can help you dissect the physiological and environmental factors that impact your mind. - Periodic recaps: a story of your week, including what shaped your mental states, what patterns are emerging, what to watch, and what to change. - Capture on the go: capture in-person conversations from your iPhone and pick up your insights right where you left off on Mac. - Privacy first: you decide what’s captured and what isn’t, and when something is stored or deleted. WHO IT'S FOR Soma is for anyone who wants to understand their own cognitive patterns better, whether that's staying sharp under work pressure, managing stress as a caregiver, or building mental resilience for competition. If you're curious what your voice reveals about your state of mind, Soma's for you.

Verdict

The call

Function Health and Soma both sit at 4.9 stars, but that hides the real split: 100% of Soma's written reviews are positive against 62% of Function Health's. Soma also leads on monetization model (free vs subscription). Function Health's advantage is ratings volume (25K vs 4) and chart position (#160 vs unranked). On price, rating, update cadence and ads there is nothing between them.
