Independent evidence report
Evidence and review signals
This is where the page changes from an app-store listing into an evidence report: findings, important reviews, pricing and a dated history.
Which version this describes
When we ran this analysis, and what the store lists now.
This analysis describes version 4.10 of the app, analyzed 2026-10-05 . The app may have changed since.
The store currently lists version 4.10, updated 2026-09-11.
What we measured
Each line is a measurement published as a measurement, never a verdict.
Each line is a measurement, published as a measurement. Where we have not looked, the line says so rather than reading as a zero.

Themes reported by reviewers
No theme reported
Counted from the reviews we have read for this app. "No theme reported" means no theme reached our reporting threshold — it is not a finding that nothing is wrong with this app, and we do not say it is.
Five-star share of ratings
80–89% five-star
Arithmetic on the stores' own published rating counts. It says nothing about why the ratings fall where they do.
In the package we scanned
No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence about the app, not a finding about it.

What the analysis found
App-specific findings, grouped by what each one rests on. How they are graded lives on its own page.
One source only — shown, not confirmed 1
A single kind of evidence. We publish these because withholding them would be the bigger distortion, and we do not treat any of them as a finding we stand behind.
Reported by users: States a price, or offers a one-time purchase
The app's own text offers a one-time or lifetime purchase, or reviewers report that the price is stated clearly.
What we saw: Reviewers report clear pricing: raised by 6 distinct reviewers (1.2% of 500 reviews scanned)
Highlighted reviews

“Works great — I love how they did a one time fee instead of making it a subscription. Excellent layout. Helping me address a low heart rate issue while sleeping. Because of this app I was able to figure out certain things that apparently…”
“Great apps for heart and sleep monitoring — I’ve used the HeartWatch and AutoSleep apps from Tantissa for several years. They work well together with the Apple Watch sensors and the iPhone to monitor multiple aspects of heart and sleep…”
