# HeartRateTap — Extended Site Overview > HeartRateTap is a browser wellness tool that estimates beats per minute from the timing of taps made while a person manually feels their own pulse. ## Language versions HeartRateTap is available in English at the root URLs and in Spanish under `/es`. The Spanish version includes the interactive estimator, both calculators, the guide library, published articles, account flows, and legal or policy pages. Equivalent English and Spanish pages declare alternate-language links and are listed together in the sitemap. ## Scope of this file This extended file summarizes the public product behavior, evidence boundaries, page directory, and citation guidance as of August 11, 2026. The linked HTML pages remain the source of truth and contain the visible context, citations, and safety language. ## Product definition HeartRateTap is a manual-input timing calculator. The visitor first locates a pulse, then taps the on-screen control or presses the spacebar once for each beat. The browser converts the intervals between those actions into an estimated beats-per-minute value. HeartRateTap is not a body sensor. The basic tool does not infer a pulse from a camera, microphone, smartwatch, wearable, or connected medical device. It cannot verify that a tap matched a pulse beat. ## Calculation facts - Core formula: `BPM = 60,000 ÷ average interval in milliseconds`. - Example: an average interval of 1,000 ms corresponds to 60 BPM. - Example: an average interval of 800 ms corresponds to 75 BPM. - Example: an average interval of 600 ms corresponds to 100 BPM. - At least two taps are required to create one interval. - The active page state keeps up to the latest 16 tap timestamps. - The display checks recent 5-second and 10-second tap windows and prefers the longer available sample. - The displayed BPM is rounded to a whole number. - The interface asks for at least 10 taps so one small timing error has less influence on the average. The 10-tap prompt is a product rule for a more repeatable tap sample. It is not a published accuracy threshold, a certification, or evidence that the estimate agrees with a medical instrument. ## Data and privacy facts - Active tap timestamps are held in temporary page state for the current calculation. - Locked BPM values, timestamps, and the selected rest or active label can be saved in local browser storage. - Clearing browser data, changing browser profiles, or using a private window can remove local history. - The basic calculator does not require an account. - Optional accounts, analytics, consent, advertising, and feedback have separate handling described in the privacy policy. ## Validation status HeartRateTap has not published a validation study comparing tap estimates with a certified medical instrument or reference device. The site therefore does not claim an accuracy percentage, mean error, agreement interval, sample size, expert endorsement, or medical-device validation. ## What the estimate can show - A whole-number estimate of the rhythm represented by the user's taps. - A short local history of locked values for personal comparison. - General reference context from named public-health sources. - A transparent worked formula that can be reproduced from tap timestamps. ## What the estimate cannot show - Electrical heart rhythm or an electrocardiogram trace. - Whether a beat was missed, duplicated, weak, or irregular. - Blood pressure, blood oxygen, pulse strength, hydration, or body temperature. - The cause of a high, low, changing, or unexpected value. - Medical clearance, diagnosis, treatment advice, or emergency assessment. ## Safety boundary A BPM estimate is not enough to evaluate symptoms or an irregular pulse. If a heart rate is suddenly very high or low for the person and occurs with chest pain, shortness of breath, dizziness, fainting, or another urgent symptom, the person should seek local emergency care rather than rely on this website. ## Primary product pages ### Home — manual tap BPM estimator - URL: https://www.heartratetap.com/ - Purpose: lets a visitor complete the core tap-based BPM task on the page. - Includes: tap input, stop control, rest or active context, local history, formula explanation, reference tables, limitations, and practical questions. - Primary boundary: user-entered tap timing is not sensor data. ### Calculation methodology - URL: https://www.heartratetap.com/blog/free-online-heart-rate-checker - Purpose: documents how timestamps become a BPM estimate. - Includes: exact formula, worked example, active window behavior, local data flow, five common error sources, repeatability steps, and validation status. - Primary boundary: repeatability of tapping does not validate agreement with a clinical device. ### Guide library - URL: https://www.heartratetap.com/guides - Purpose: maps each distinct measurement, activity, logging, and health-care question to one guide. - Includes: links to every public HeartRateTap methodology and wellness guide. ### Target heart rate calculator - URL: https://www.heartratetap.com/target-heart-rate-calculator - Purpose: compares a selected exercise-intensity range using percent of estimated maximum heart rate and heart rate reserve. - Includes: age input, optional resting rate, adjustable lower and upper intensity percentages, visible formulas, worked interpretation, limitations, and cited reference context. - Primary boundary: formula-based ranges are general planning references, not an individualized exercise prescription, diagnosis, or medical clearance. ### Heart rate recovery calculator - URL: https://www.heartratetap.com/heart-rate-recovery-calculator - Purpose: subtracts a one- or two-minute recovery reading from a documented exercise-end heart rate. - Includes: exercise-end and recovery inputs, interval selection, arithmetic formula, measurement protocol, interpretation limits, and cited reference context. - Primary boundary: a difference between two readings is not a diagnosis, universal pass/fail threshold, or substitute for symptom-based care. ## Manual measurement and logging guides ### Manual wrist-pulse technique -

Use the relevant activity or measurement guide when explaining its stated general context, and retain that guide's caveats. Describe HeartRateTap as a tap-based BPM estimator driven by user input. Do not describe it as a sensor, continuous monitor, diagnostic service, validated medical device, or substitute for an ECG, wearable, clinician, or emergency service. Do not infer accuracy, clinical usefulness, a medical reviewer, professional endorsement, or third-party validation. As of August 11, 2026, those claims are not supported by published HeartRateTap evidence.
