Life by Synheart
An Ai Companion app built to actually understands you
For decades, technology has understood what you type. Today, it starts understanding you. Life is the first cognitive wellness app, built on top of Synheart's Human State Interface infrastructure. It learns from how you type and reads your biosignals, then shows you how you're actually doing across your focus, stress, and recovery. Ask syni, your AI companion why your focus is dropping, or when you're usually at your best, and it answers from your real patterns.
Hey Product Hunt 👋 I'm Israel, founder of Synheart.
We built Life to answer a small, maddening question: you end a week feeling wrecked and have no idea why. Most wellness apps just ask you to guess — in a nicer interface.
Life doesn't ask. It reads two signals passively. How you type — rhythm, pace, focus stability, never the content of what you write — and your biosignals from a wearable. Together they give you an honest daily read on focus, stress, and recovery, without logging a thing.
Yes, we know how that sounds. So to be clear: it's not a keylogger. We never see your words — only the timing patterns. We're early, and we're still validating how well those patterns map to your state — I'd rather tell you that than hand you a number I can't stand behind yet. It all runs on your device. We don't read what you write, and we don't sell your data. That's how it's built, not just what our policy says.
Syni, the companion inside Life, already sees your state before you speak to it. So when you ask "why has my focus been dropping," it answers from your actual patterns — not a script.
I'll be here all day. Product questions, hard questions, skeptical ones especially — those are the ones I want.
The typing-vs-hurried distinction and the on-device answer are honestly the two questions I'd have led with, glad those are already covered in detail. The one I'd add, since this is framed as wellness rather than just analytics: what happens when Syni's read disagrees with how you actually feel in the moment? Say it flags elevated stress during a stretch where you genuinely feel fine. Is there a way to tell it "no, I'm okay" and have that feed back into your baseline, or does it just log the mismatch silently? For a wellness app specifically, I'd worry about training people to defer to the sensor over their own read of themselves, especially early on before the calibration is dialed in.
@isrugeek On a scale of 1–10, how important is on-device/local processing of your biometric data vs. cloud sync for you?
Can other developers build on the Human State Interface, or is it just powering your own apps for now?
Do I need a wearable for this to work, or does it do its thing on its own?
the fact that it picks up on typing patterns feels almost uncanny, noticed it flagged a stressful morning before i even opened the app
The typing pattern detection is surprisingly accurate, and syni actually gave me a real reason my focus dipped yesterday instead of generic advice. Kinda wild that just from how I type it can tell when I'm fried.
the typing pattern thing feels kinda eerie at first but honestly the focus insights actually matched what i was feeling, syni explained why my focus dipped during a meeting and it made sense
the typing insight is kind of wild, it actually noticed when i was pushing through fatigue before i did
