What the niche is
A pulse from the camera, then a journal: heart rate, HRV, a blood pressure log, a blood sugar log, reminders, a PDF for the doctor. The reading takes the phone; the journal keeps the subscription.
It sits inside heart rate and health monitoring, next to blood pressure logs and sleep trackers. Same fingertip trick, forty developers, one price sheet.

“doesn't work” recurs in 10 of the top 12 apps
Phrases that recur in one and two star reviews across 12 of the niche's top 12 apps.
Across twelve leaders with pooled reviews, three complaints.
It does not read blood pressure. 378 mentions in all twelve apps, plus "measure blood" 136 times in eleven, "take blood" 43 times in ten, "blood sugar" 328 times in ten. The quotes are from nurses and healthcare workers who tested the claim: the app opens a form and asks you to type in the cuff reading. "False advertising" runs 73 times through ten apps.
The paywall comes before the first reading. "Free trial" 62 times in ten apps, and the loudest quote in the niche: they will not let you start using the app without first making you subscribe, at seven dollars a week to record your BP.
The number is wrong. "Doesn't work" 50 times in ten apps. A red cup on the lens returned a heart rate. An Apple Watch read 86, the app read 103. Held next to an oximeter for a minute, the app disagreed.
What works, from the five star side
"Blood pressure" is also the top five star phrase, 77 mentions in twelve apps, and the quotes say the readings match the cuff and the doctor's office. "Keep track" runs 21 times in eight apps: the log catches people doing too much. "First time" in seven apps, users amazed the camera does it at all. "Muy buena" runs 23 times in seven apps; the Spanish-speaking user is a visible slice of every leader's reviews.

What to copy and what to avoid
From the price sheets and the pooled reviews above.
Copy: the journal. The five star reviews praise the log across eight apps and the cuff comparison across twelve. The reading gets the install, the record keeps the subscription.
Copy: the $29.99 to $49.99 year. Ten of the fourteen leaders list one.
Avoid: claiming blood pressure or blood sugar from the camera. 378 and 328 mentions, in twelve and ten leaders, and the reviewers work in healthcare.
Avoid: the paywall before the first reading. "Free trial" runs through ten of twelve leaders, and the top quote in the niche is about being charged before seeing whether it works.
Our read: 36 of 93 listings promise blood pressure from the camera, and that promise is the entire one star pile. A listing that promises the pulse and the log inherits the installs without the reviews.
Our read: one app reads the cuff with the camera instead of pretending to be one, launched March 2025, already $50–250k. Two apps export a PDF for the doctor. Both angles answer the reviews the leaders keep getting.
