## What is Vigor?

Vigor turns the health data your watch or fitness tracker already records into a single body energy score from 0 to 100 - it charges when you rest and drains when you are stressed or active, so you can see at a glance whether to push hard or take it easy. Works with any tracker that writes to Apple Health. Inspired by the energy-reserve gauges on other fitness watches, but built independently on Apple Health and computed entirely on your iPhone.

WHAT YOU GET

A day chart showing your whole day as one energy curve, with an activity intensity band behind it, your morning peak, and tappable markers for sleep, naps and workouts.
An overnight recharge that follows your night minute by minute - deep sleep, time awake, and your heart rate while you sleep - so a restless night and a restful one no longer land in the same place.
A ledger of everything that charged and drained you today - what, how much, when and for how long.
A sleep projection: what you will wake near if you sleep now, and how much sleep it takes to reach a good level.
A morning readiness card: a recovery score built from your night, your heart data, and yesterday’s load.
A live 0 to 100 body-energy dial with color zones and a plain-language read.
A weekly summary, a 30-day history with a trend line, and “Your patterns” insights on how sleep moves your mornings.
Day tags (alcohol, caffeine, sickness, travel) and gentle / balanced / responsive sensitivity presets so the model fits YOUR body - plus a sleep need setting and a recalibrate button.
An optional Apple Watch app with the score, the day’s totals and the energy curve on your wrist - plus complications and Home Screen, Lock Screen and StandBy widgets, including a full-day-curve large widget.
A morning briefing and an optional evening outlook on what tonight’s sleep sets up for tomorrow.
Circles: invite friends and see each other’s energy at a glance - opt-in, via your own iCloud. Nudge someone who runs low; only your name and score are shared, never your health data.
Eight different looks, each with light and dark palettes: editorial, cute mascot, true-black OLED, calm nature, a cat whose pose tracks your energy, retro pixel, gold-threaded silk, and formal navy. Switch anytime, try them on live.
HOW IT WORKS On first run Vigor reads about two months of your Apple Health history (heart rate variability, heart rate, resting heart rate, sleep and its stages, workouts, active energy, wrist temperature, VO2 max) and builds a personal baseline, so you get a personalized score right away. Overnight it sets your morning starting level from how well you actually slept - your sleep stages, time awake, and your sleeping heart rate; through the day your heart rate and activity move the number up and down. Naps give a bounded boost, and workouts count even without heart-rate data. It is a running balance, like a battery for your body.

PRIVATE BY DESIGN No Vigor account, no Vigor server, no ads, no third-party tracking, no analytics. Your health data never leaves your iPhone. The only thing you can choose to share is your energy score: opt-in Circles sends your display name and current score to the friends you invite, via your own iCloud, never a Vigor server. You can turn off Vigor’s Health access anytime in iPhone Settings.

NO SUBSCRIPTION Vigor is a one-time purchase - no subscription, no in-app purchases. It works in 10 languages and follows your phone’s language.

## Version history (last 5 releases)

### 1.4.2 — 2026-08-25

Working on solving bug with circles

### 1.4.1 — 2026-08-23

Solved a bug with Circles where the users could not connect and share

### 1.4 — 2026-08-21

Circle is now one to one.

Every friend is a separate, private connection. Your friends can no longer see
each other, and nobody can see who else you are connected to.

- Both people agree. Someone entering your code sends you a request you accept
  or decline. Nothing is shared in either direction until you accept.
- Choose what each friend sees. Tap a friend to set it for that person alone -
  the trend arrow, your morning start, how much the night gave back, your
  average morning, your streak, or the shape of your day. Pause anyone without
  disconnecting.
- Tap a friend for their detail screen, with the nudge history between you.
- The nudge buttons now confirm when they land, and 100 avatars replace the old
  24.

New on the Today screen

- What shaped today: the day's biggest recharge and biggest drain, with real
  times and a plain reason for each.
- Rest of day: where your reserve is heading, and when - drawn on the curve, and
  honest when it cannot say.
- How this morning was built: the full arithmetic behind your starting number.
- The curve now carries a band showing how sure Vigor is, plus how much of your
  waking day was actually measured.
- Your day rhythm: the calm heart rate your body actually rests at, hour by
  hour, and the rate below which you are recharging.
- Export everything Vigor computed about you as CSV and JSON.

Apple Watch

- Right now is genuinely live - your heart rate updates while you look at it.
- The complication ages honestly instead of showing an old number as current,
  and says when a night was not recorded.
- A tag logged on your wrist now lands at the hour you logged it, and can no
  longer overwrite tags kept on your phone.
- Always-on and privacy handling throughout.
- The whole watch app is now translated into all ten languages.

Fixes

- Five health signals the model reads - respiratory rate, blood oxygen,
  overnight breathing disturbances, heart-rate recovery and mindful minutes -
  were never reaching it. They do now.
- Past days in Trends show their date.

### 1.3 — 2026-08-06

Solving some minor bugs and adapting the algorithms.

### 1.2 — 2026-07-30

Sleep quality now drives your morning score.

Vigor used to give you roughly the same overnight recharge whatever kind of
night you had. It now follows your night minute by minute - deep sleep, REM,
light sleep, time awake, and your heart rate while you sleep - so a restful
night and a restless one no longer land in the same place. A calm night and a
stressed night can now differ by more than two to one, which is what a night
that actually felt different should look like.

- Your night is now drawn like the rest of your day, with the heart-rate band
  running under the whole curve instead of stopping at bedtime. Time spent
  awake at night shows as a real dip.
- Being awake in the night costs energy. Before, it counted for nothing.
- A high heart rate while you sleep holds the recharge back, and Vigor will
  now tell you when that is what limited your night.
- Daytime drain recalibrated: quiet days cost noticeably less, busy days are
  unchanged. Chronically short sleep no longer pins you at the bottom.
- Deep sleep is now valued above light sleep, and light sleep above REM, which
  matches how the body's recovery signals actually behave overnight.
