Description
Turn your iPhone into a pocket heart‑rate monitor. See live heartbeat waves, track rhythm trends, export PDF for your doctor—no wearables, no camera. Wellness only.
Meet HeartScan — the first phone‑only heart‑rate monitor that shows what your smartwatch can’t.
Lay back, place the iPhone on your chest, hold still for 60 s. HeartScan turns micro‑vibrations into a real‑time cardio‑wave so you can see every beat, not just count it.
Why people use HeartScan
• Instant pulse & rhythm check — reassurance for skipped beats, palpitations, post‑COVID tachy.*
• Training insight — athletes visualise stroke‑volume trends between VO₂ sessions.
• Recovery tracking — post‑MI patients watch mechanical strength rebuild day by day.
• Doctor‑ready PDF — export a clean report that cardiologists understand.
Key features
▸ Accurate heart‑rate (BPM) powered by AI + seismocardiography (SCG)
▸ Cardio‑wave viewer — see each systole & diastole in motion
▸ HrV snapshot — variability graph for stress insight
▸ Session history — compare today vs last month
▸ PDF & CSV export — share or archive your data
▸ Works on any iPhone 8+ — no camera flash, no extra hardware
How it works
Lie flat on a sofa or bed.
Open HeartScan and hit Start.
Place the phone mid‑sternum or apical region.
Breathe normally for one minute.
Review BPM, wave, rhythm and HRV.
Behind the scenes, our neural model filters out breathing, muscle artefacts and noise to estimate mechanical systole — something optical PPG and single‑lead ECG can’t do.
Privacy first
All recordings stay on your device unless you tap ‘Export’. No third‑party analytics. Read the full policy: heartscan.app/privacy
Wellness disclaimer
HeartScan is not a medical device. It does not detect arrhythmia, diagnose disease or replace professional advice. Always consult a physician if you have health concerns.

Ratings and Reviews
Spelling errors and no summary of findings
It’s difficult to understand the significance of the readings without a summary. Also cycle is incorrectly spelled “Circle” and “cicle”.
Developer Response ,
We understand the challenge of interpreting the readings without a clear summary and the importance of accurate information. Due to legal constraints, we can't provide medical advice, but we're committed to enhancing the app with more comprehensive information. This will help users better understand their results in a straightforward manner. Additionally, we appreciate you pointing out the spelling mistakes and will address these errors promptly
Diagnostics
It’s a great analysis but there’s not enough information about how to read the info. The app needs a written overview of what the diagnostic data means health-wise.
When should you be alarmed, contact your physician, head to emergency, etc.
I did a scan and there was red all over it. I went online but couldn’t figure out good and bad or how bad is bad.
I scanned my husband and his reports had no red lines and everything was in the normal range. His Seismocardiogram had 0 deviations while mine had 14.
Developer Response ,
Thank you for your feedback! We're glad you find the analysis helpful. We understand the importance of clear guidance and will work on adding more explanations within the app. It's always recommended to share your results with a physician for proper interpretation (using our "export as PDF" feature). Feel free to suggest any improvements you'd like to see.
Useless
Just downloaded the app for the first time, did the scan and I can’t access any of the results without paying! And it says my free subscription expired… I’ve had the app for less than 5 minutes and never used any free subscription. Why on earth would I pay $20 per month without a trial to see if I like it. No thanks! Don’t bother downloading unless you just want to pay right out the gate.
Developer Response ,
Thank you for your feedback, Jillean. We apologize for the inconvenience you experienced. Based on user feedback, we have revised our subscription scheme to include a free trial for new users. Please contact us directly, and after a short interview, we'll provide you with six months of free access to our app. Your input is very important to us, and we appreciate your understanding.
