Welltory and Pulse Rate measure the same way — a fingertip on the iPhone camera. The difference is where each one draws the paid line, and Welltory draws it around the numbers most people came for.
Start with what is not in dispute: Welltory measures heart rate variability through the smartphone camera, exactly as Pulse Rate does. Both are photoplethysmography — the lens and flash read the colour change in your fingertip as blood moves through it. So this is not an argument about sensors; it is an argument about where the paywall sits. Welltory publishes two plans on its own pricing page: $99 billed once a year, or $599 as a one-time lifetime payment, after a three-day free trial. Its free tier gives you the three headline scores — stress, energy and productivity — plus a basic blood-pressure interpretation and daily heart reports. Premium is what adds the 21 detailed heartbeat metrics, ten further blood-pressure metrics, doctor-shareable reports, lifelogging and geotracking, and the clinically validated mental-health assessments. Pulse Rate splits it differently: the instant camera heart-rate check is free with no trial clock on it, and the subscription covers comprehensive Apple Health sync, AI trend summaries and deeper recovery analysis. Which split is better depends entirely on which half you actually use, so the rest of this page is the specifics rather than the pitch.
Welltory reads the same fingertip through the same camera. The entire disagreement is where the paid line falls — and Welltory draws it around the 21 metrics most people opened the app to see.

Welltory prices and the free-versus-premium split were read from welltory.com/plans on 2026-08-24: $99 billed annually, $599 one-time lifetime, three days free. A monthly option is referenced there but its price is not published, so no monthly figure is quoted above.
Welltory and Pulse Rate are the rare pair that genuinely share a measurement method. That makes the comparison unusually clean: strip the sensor question out and what is left is pricing structure and depth.
Photoplethysmography: the flash lights the fingertip, the lens watches the colour shift as blood moves through it, and the beat-to-beat timing falls out of that signal. Neither app needs a strap, a band or a ring. Any difference in your numbers comes from the analysis layer, not from a better sensor.
Welltory’s free tier gives stress, energy and productivity scores, a basic blood-pressure interpretation and daily heart reports. The detailed 21-metric heartbeat breakdown, the ten extra blood-pressure metrics and the shareable reports sit behind $99 a year or $599 for life, after three free days. In Pulse Rate the measurement itself never expires.
Welltory interprets a blood-pressure reading and stacks ten further metrics on it, then packages that for a doctor. Pulse Rate logs blood pressure you type in and charts the trend — it never measures or interprets it, and it is not a medical device. If a structured BP workup is why you are here, that is Welltory’s page to win.
Pulse Rate computes RMSSD, turns sessions into TRIMP training load, and syncs both directions with Apple Health — so a camera reading sits next to whatever an Apple Watch already recorded, and VO₂ max and heart-rate recovery come through from there rather than being invented from the camera.
When the sensor is identical, the interesting differences move up a layer: what each app derives, and what it charges for deriving it.
| Detail | Welltory | Pulse Rate |
|---|---|---|
| Sensor | Phone camera and flash, fingertip | iPhone camera and flash, fingertip |
| Headline output | Stress, energy and productivity scores | Heart rate, RMSSD and recovery |
| Depth on free tier | The three scores, nothing beneath them | The full instant heart-rate measurement |
| Training load | Not a TRIMP-style load model | TRIMP calculated from session intensity and duration |
| Blood pressure | Interpreted, with 10 extra metrics on premium | Manual entry and trend history only — never measured |
| Health-app data | Draws charts from connected health apps | Two-way HealthKit sync, including VO₂ max and HRR |
| Trial clock | Three days, then premium features lock | No clock on the core measurement |
Welltory is a serious app with a real depth advantage in places. Read this before installing anything, not after.
Yes, and that is the honest starting point. Both use photoplethysmography through the iPhone camera and flash: you rest a fingertip over the lens and the app reads the periodic colour change caused by blood volume. Neither needs a chest strap, a wrist band or any external sensor. Any difference in the numbers you see comes from the analysis layer and how each app handles a noisy reading, not from a different kind of sensor.
Welltory publishes two plans on welltory.com/plans: $99 billed once a year, and a $599 one-time lifetime payment for full access forever. New users get three days free to try premium. A monthly option is referenced but its price is not shown on that page, so treat any monthly figure you see quoted elsewhere as unverified. Over three years the annual plan comes to roughly $297, which is the number worth comparing against — the lifetime price only pays off if you are still using it in year six.
Per Welltory’s own plan comparison: basic heartbeat analytics limited to the stress, energy and productivity scores, a basic blood-pressure interpretation without the extra metrics, daily heart reports, and manual weight and blood-pressure logging. What premium adds is the depth — the 21-metric heartbeat breakdown, ten more blood-pressure metrics, shareable reports for a doctor, lifelogging with geotracking, the validated mental-health assessments, and the advanced charts drawn from other health apps. If the three scores are all you wanted, the free tier is genuinely usable.
Blood pressure, and it is not close. Welltory interprets a blood-pressure reading and layers ten additional metrics on top of it, then packages that into a report you can hand to a doctor. Pulse Rate does not do that: it logs blood pressure that you type in yourself and charts the trend over time, and it never measures or interprets blood pressure at all. If a structured blood-pressure workup is the reason you are installing something, install Welltory. The same applies to its clinically validated mental-health assessments, which Pulse Rate has no equivalent for.
When the thing you want daily is a heart-rate and HRV reading that does not run out. Pulse Rate keeps the instant camera measurement free with no trial expiry, computes RMSSD, calculates TRIMP training load, and syncs both ways with Apple Health — so camera readings sit alongside whatever an Apple Watch or another Health source has already recorded, and VO₂ max and heart-rate recovery come through from there. The subscription covers comprehensive sync, AI summaries and deeper trend analysis rather than the measurement itself.
Three things, stated plainly. It is iOS only — there is no Android build, so if you are switching to an Android phone this is the wrong answer. It measures on demand rather than continuously; there is no background monitoring through the night. And it is not a medical device: no ECG, no blood-oxygen reading, and blood pressure is manual logging only. Those limits are the same shape as Welltory’s camera-based readings, but it is better to read them here than to discover them after installing.
