Estimated revenue

A model estimate with a likely range, not a reported figure.

No estimate. Apps outside the grossing charts, and some countries, have no reliable rank-to-revenue curve, so we show nothing rather than a guess.

How this estimate is made

Rank: we take the app's best Top Grossing rank on the latest chart day. Category ranks are converted into an equivalent overall rank, because a #10 in Finance earns far less than a #10 overall.

Curve: that equivalent rank is read off a rank-to-revenue curve anchored on public company revenue and market-data reports for the US iPhone App Store.

Country: the curve is scaled per country (Japan is roughly a third of the US, Türkiye under 1%). Where we have no scale, such as China, there is no estimate.

Range: the likely range widens with country, category and chart depth. It is a plausible span, not a statistical confidence interval.

Not included: ads, payments outside the App Store, and any difference between gross sales and what the developer keeps. Low confidence means indirect data; medium means several independent sources agree.

All your health in one app: chronic stress & energy tracker

Trusted by over 20 million people, featured in the App Store under Apps We Love, and collaborating with 30+ universities, including Harvard Medical School, Arizona State University, and Johns Hopkins, to advance health science.

Welltory helps you understand your heart

Sometimes your body feels hard to decode. Welltory turns its signals into insights to help you manage chronic stress, track energy reserves, navigate fatigue, and take charge of your long-term health.

By analyzing heart rate variability, a proven health marker backed by 20,000+ studies, Welltory shows how your nervous system, sleep, and lifestyle impact how you.

Track and reverse chronic stress

Daily stress impacts your energy reserves, especially if you’re living with POTS, Long COVID, or ME/CFS. Turn your Apple Watch or wearable into a stress monitor. See how work, emotional pressure, and physical effort affect your baseline, and catch stress spikes before they take a toll or trigger a crash.

Get your energy back

Welltory tracks your body’s daily battery level in real time so you can pace your day, prevent sudden crashes, and know exactly when to push or pause.

Track sleep & recovery

Find out what’s disrupting your deep sleep, evaluate nighttime recovery, and access science-backed audio programs designed to help you fall asleep faster and wake up refreshed.

Decode your health patterns

Log flare-ups, crashes, and life events in your Journal. Connect your symptoms to HRV, stress, and recovery trends so you can spot hidden triggers and pace your energy with confidence.
Track your migraines
Log episodes, symptoms, and intensity alongside sleep and heart rate data to identify what triggers your migraines and map your patterns over time.
Turn data into insights
Stop juggling single-purpose health apps. Connect 1,000+ devices, wearables, and apps, including Apple Watch, Oura, Garmin, meditation tools, and lab results, into one smart health hub.

Monitor blood pressure & heart health

Keep tabs on hypertension, resting heart rate, and cardiovascular trends. Log readings manually or sync a blood pressure monitor to generate detailed PDF health reports you can share with your doctor.

Note: Welltory reads HRV via camera or wearable sensors; it does not measure blood pressure directly via phone camera or Apple Watch.

Track workouts & move without crashing

Balance exercise with proper recovery. Welltory tracks active movement, including daily chores, walking, and intense workouts, and sets personalized longevity targets to help you avoid burnout.

What’s new

Release notes for the latest version, as written by the developer.

v4.63.0

Something big is taking shape in our corner of the lab — and we can’t wait to show you.

This release looks quiet on the surface, but our team is deep into the kind of work that takes time to get just right. We’re not ready to spill the beans yet — let’s just say it’s worth the wait, and you won’t have to wait long.

In the meantime, we’ve tightened a few bolts so Welltory runs a little smoother every time you open it.

Stay tuned & rate us if you enjoy using Welltory.
