Tensly
Your nervous system,simplified
Free · In-App Purchases · Designed for iPhone. Not verified for macOS.
Your nervous system in one glance. Tensly reads
your Apple Watch signals and tells you how your
body is actually doing — before you have to ask.
Tensly detects stress before you feel it — using
the signals your body is already sending.
Most stress apps ask how you feel. Tensly doesn't.
Instead, it reads your heart rate variability
through Apple Watch and learns what calm looks like
for you specifically. When your nervous system
shifts, Tensly notices — quietly, in the background,
without interruption.
HOW IT WORKS
During the first 7 days, Tensly establishes your
personal baseline by learning your unique
physiological patterns across different times of day
and activity levels.
After that, it runs silently in the background. When
stress builds in your body — often before you
consciously feel it — Tensly surfaces a gentle
insight and suggests a simple action to help your
system recover.
WHAT YOU'LL SEE
Your current state in plain language — Good, Busy,
Stressed, or Overwhelmed — with a calm explanation
of what your body is doing right now.
A living visual that changes color and moves with
your nervous system state. Not a number. Not a
chart. Something you can feel at a glance.
A personal insight generated from your actual
signals — not generic advice. When you're stressed,
a guided breathing session uses your real HRV data
to select the right technique and confirms recovery
only when your body actually responds.
Your sleep from last night shown alongside your
current state, so you understand the full picture.
WHAT MAKES TENSLY DIFFERENT
No mood logging. No journaling. No daily check-ins.
Detects stress through heart rate variability —
not self-reporting.
Personalized to you, not population averages. Your
baseline is yours — built from your own data over
time.
The breathing session ends when your HRV recovers —
not when a timer runs out. Your body confirms it,
not the clock.
Works passively. Open it when you want, ignore it
when you don't.
All data stays on your device. Nothing is sent to
any server.
REQUIRES
iPhone with iOS 17 or later and Apple Watch Series
4 or later. Apple Watch must be worn regularly for
accurate readings.
PRIVACY
Tensly is built privacy-first. All physiological
data is processed locally on your device using
Apple's HealthKit framework. No account required.
No data leaves your phone.
Tensly is a wellness tool, not a medical device.
It does not diagnose, treat, or prevent any
condition. Always consult a healthcare provider
for medical concerns.

A significant update to how Tensly looks, feels,
and works.
NEW DESIGN
The dashboard is completely redesigned. Cleaner,
calmer, more focused. Your state — Good, Busy,
Stressed, or Overwhelmed — is now the first thing
you see. Everything else is one tap away in a
detail sheet below.
A new living visual at the center of the screen
changes color and moves organically with your
nervous system state. No numbers. No rings. Just
something you can feel.
GUIDED BREATHING SESSION
When you're stressed, a full-screen breathing
session opens with a choice of technique matched
to your current state. The session plays ambient
music, guides your breath with a visual pacer,
and ends only when your HRV actually improves —
confirmed by your Apple Watch, not a timer.
Completed sessions are saved to Apple Health as
Mindful Minutes.
SLEEP CONTEXT
Your sleep from last night now appears alongside
your current state, so you can understand why
your system is where it is today.
NEW STATE NAMES
Your nervous system state is now described in
plain language: Good, Busy, Stressed, Overwhelmed.
No clinical terms. No jargon.
