Vigor: Body Energy
Energy score, no subscription
$2.99 · Designed for iPhone. Not verified for macOS.
Every heart-rate reading your Apple Watch takes now counts toward your energy. And in Circle, a tap on your own name shows exactly what each friend sees.
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.

Every heart-rate reading your Apple Watch takes now counts.
Newer watches can measure your heart every few seconds, but Vigor used just one of those readings every five minutes at rest. It now uses all of them, day and night, so your energy follows your heart more closely - and it may read slightly differently from before on a watch that measures often. An event's heart-rate chart also says how many readings it is drawn from, and leaves a gap where nothing was measured instead of drawing a line across it.
- See what your friends see. Tap your own name in the Circle tab to see exactly what each friend receives from you, and change it right there.
- The choices you set for new friends now apply when you add someone.
- Every friend's number says how long ago it was measured, so an old number no longer passes for a fresh one. And when your phone hears from a friend, it now sends your latest number back.
- Charts open full screen only when you tap them - not after you drag along the line, tap a bubble, or open "What the lines mean".
- On the Apple Watch: tapping the Tonight complication opens the Tonight page, and Tonight now plans with your own recent nights, as your iPhone does.
- Wrist temperature shows the change from your usual level, as its explanation always said.
- The Metric units switch works: turn it off for Fahrenheit and Calories.
- Cardio fitness shows how much it has changed over time.
- Insights: workout-day averages include yesterday, and the workout card appears only when there is something to compare.
- Data coverage no longer reads "91 of the last 90 days".
- The medium widget no longer cuts its title short.
- German: spelling corrected in 28 phrases.
Requires iOS 26 and watchOS 26.
