Monitor health with the stress test and pulse checker in the heart rate app.
ECG Logger for Polar H10 ships three uncaptioned device captures, including one dominated by the Android quick-settings shade, so every claim rests on the title alone. Welltory: Heart Rate Monitor captions each frame ("Take heartbeat measurements", "Sync up to 140 apps & gadgets") and adds a shield badge reading "Your health data, safe and secure". For an "ecg recorder" searcher the ECG Logger title matches intent better, but the Welltory screenshot set does far more selling.

Only the first 4 screenshots from each side are sent to the AI. These are what users see in App Store and Google Play search results, so they carry most of the conversion weight.

App B
Value Proposition
TiedTitle and short description name the exact job and the required sensor, but none of the three screenshots carries a benefit line.
Hero reads "All-in-one health app" with "Powered by AI"; concrete only lower down at "87% Stress" and "42% Energy".
Clarity
B leadsConnect / Record / Open controls and the "ECG (µV) Pulse (bpm) R-R (ms)" legend are concrete, but screenshot 2 is mostly the notification shade.
Every frame names a function in plain words: "Take heartbeat measurements", "Sync up to 140 apps & gadgets", "Check in with your body".
Emotional Hook
B leadsThree raw captures with visible battery and nav bars; the 7.66 MB dense trace shows data volume, never a reason a user would want it.
Illustrated hand taking a fingertip reading, plus "Stress is taking a toll" copy, but the outcome text sits on a UI card, not on a person.
Trust Signals
B leadsNo badge, user count, or endorsement anywhere in the three screenshots; the ecglogger.com site is mentioned only inside the description text.
Shield icon with "Your health data, safe and secure"; Johns Hopkins and Harvard mentions stay buried in the description, unseen by browsers.
Reviews of ECG Logger for Polar H10 concentrate on two recurring frictions: the recording paywall appearing with no price shown before purchase, and saved sessions that fail to open or come back empty, while praise clusters around traces detailed enough for cardiologists and a no-frills CSV workflow. Reviews of Welltory: Heart Rate Monitor are dominated by subscription friction, repeated upsell prompts after purchase, and an unclear split between free and premium tiers, set against consistent praise for the depth of its HRV insights and daily readiness guidance. Both listings draw sync or reliability complaints, but the monetization thread is far heavier in Welltory: Heart Rate Monitor reviews.

Medium"ECG Logger for Polar H10" positions as a device-bound capture tool: it names one sensor in the title and promises live view, background recording and CSV/PDF export of raw ECG and R-R intervals. "Welltory: Heart Rate Monitor" positions as a sensor-free consumer health interpreter, leading with camera-based HRV, stress, blood pressure and the claim that its method is "as accurate as ECGs (EKGs)". For the query "ecg recorder" the two stances barely overlap: one sells the recording itself, the other sells a substitute for needing one.
App A
Positioning
Device-specific ECG capture tool
Target audience
Polar H10 owners who want raw ECG files
Value promise
Record, view and export your Polar H10 ECG as usable files
Tone
feature-focused, technical, disclaimer-forward
App B
Positioning
All-in-one consumer health tracker
Target audience
Phone-only users tracking stress, pulse and wellness
Value promise
Camera-measured HRV that reveals heart health without extra hardware
Tone
credential-led, benefit-rich, consumer-wellness
Gap
"ECG Logger for Polar H10" leads with hardware-bound raw signal capture and file export, while "Welltory: Heart Rate Monitor" leads with no-hardware inference, citing "16 million users" and Johns Hopkins to argue a phone camera is enough.
Opportunity
For the searcher who typed "ecg recorder" because they already own a chest strap and want the actual waveform, "ECG Logger for Polar H10" can claim the literal reading of the query that "Welltory: Heart Rate Monitor" explicitly argues around.
Risk
The listing spends its first impression and a large block of body copy on constraints (one compatible sensor, "not approved, developed or supported by Polar", "not a medical device"), so a browsing user who does not yet own an H10 self-selects out before seeing the export and long-recording strengths, and the disclaimer density can read as hedging rather than candour.
Strategic advantage
Raw data ownership is the edge: automatic 1-hour file splitting, CSV that opens in Excel and PDF export speak directly to quantified-self and clinically curious buyers who want evidence they can keep and re-analyse, not a wellness score they cannot audit.
Missed opportunity
Neither listing owns the clinical handoff moment: "ECG Logger for Polar H10" frames PDF and CSV as file operations rather than as a document you hand to a cardiologist, and "Welltory: Heart Rate Monitor" cites institutions without ever addressing the doctor's appointment itself.

Welltory: Heart Rate Monitor
Strong lead
Welltory: Heart Rate Monitor holds position 2 for ecg recorder while ECG Logger for Polar H10 sits at 10, yet the wording match runs the other way: ECG Logger for Polar H10 is the closer answer to the query and still loses the click. The lead rests on presence and persuasion rather than fit, which makes it contestable.
Why it wins
Welltory: Heart Rate Monitor sells inside the listing itself, captioning every frame ("Sync up to 140 apps & gadgets") and adding a data-security badge, on top of the stronger store presence of the two. ECG Logger for Polar H10 ships three uncaptioned device captures, so a searcher scanning results for ecg recorder has little beyond the title to act on.
Biggest opportunity
The short description of ECG Logger for Polar H10 already covers ECG recording, so the gain for ecg recorder is conversion rather than coverage: raw waveform ownership, with CSV and PDF a cardiologist can actually read, is an artefact Welltory: Heart Rate Monitor never claims.
Next priority
The remaining test is whether leading with the artefact and its destination, such as "Record raw ECG with Polar H10. Export CSV and PDF for your doctor." (66 chars), lands faster than the current viewing-and-recording framing. Running it alongside captioned screenshots and the exact one-time unlock price, which reviewers say they cannot find before paying, targets the two frictions keeping ECG Logger for Polar H10 at 10 for ecg recorder.
