Health apps promise the moon. We check the receipts.
Every app gets 30 days on real wrists, a privacy teardown, and a score we can defend in public. No affiliate links, no sponsored verdicts, no “partner content.” We buy every subscription with our own money.
In-depth reviews
Thirty days minimum. Two testers per app, four when the claims are loud. Every score traces back to the rubric.
Oura App 5.0: the quiet one still wins
Best-in-class sleep staging, a readiness score that finally explains itself, and a membership fee that stings a little less than it used to.
Whoop MG: brilliant coach, brutal contract
The strain model is the best in the business. The cancellation flow is the worst thing we tested all quarter.
Zenday App: the first tracker that knows what a dose is
Built around the real GLP-1 problem — protein on a suppressed appetite, and the week after a dose increase. The best privacy model in consumer health software.
Oura vs Whoop, settled with the published data
Oura's sleep algorithm has been validated against polysomnography in 96 people and 421,045 epochs. Whoop's was validated in 12 — by a researcher the company sponsored. We read every study, wore both for a month, and did the cost arithmetic nobody else does.
Oura takes
- Sleep staging accuracy
- Battery & wearability
- Data export
Whoop takes
- Training load guidance
- Live workout tracking
- Coaching depth

Six axes. One score. Zero vibes.
Every app is scored out of 10 on six axes. We publish the raw axis scores, the test log, and the firmware versions — so you can disagree with us precisely.
Measurement validity
Does the number mean anything? We benchmark against reference devices — PSG for sleep, ECG chest strap for HR, lab draws where we can get them.
Evidence & claims
We read the studies in the footer. Company-funded, n=12, unpublished? That goes in the review, in bold.
Data rights
Trackers on launch, third-party SDKs, export formats, and whether "delete my account" actually deletes anything.
Daily UX
Thirty days of real use, plus a dark-pattern count: fake urgency, guilt streaks, buried cancel buttons.
Price & value
Total 24-month cost including hardware, and what happens to your data the day you stop paying.
Staying power
Funding, shipping cadence, support response times. Half of these companies won't exist in three years.
What moved this week
Samsung, Google, Whoop and Oura all ship conversational coaching. We could not find a single published accuracy or safety evaluation.

ReportThis is how we pay for the lab
Operators, investors and health systems buy our category data: 214 apps scored on the same rubric, pricing histories, churn signals, retention teardowns and privacy audits. Reviews stay free and unsponsored because the research desk pays the rent.
See what we sellFive people, one bench, a lot of rings
Applandica is not a content farm. It's five obsessives in a Bond Street office with a drawer full of chest straps, a home sleep lab, and a shared spreadsheet we argue about every Monday.
