  • How do I know if I have irregular heartbeats?
    In general, signs and symptoms of iregular heatbeats (arrhythmias) may include: A fluttering in the chest A racing heartbeat (tachycardia) A slow heartbeat (bradycardia) Chest pain Shortness of breath Other symptoms may include: Anxiety Fatigue Lightheadedness or dizziness Sweating Fainting (syncope) or near fainting After an ANSWatch-Mini test, AI in our app will mark a suspected irregular heartbeat by a vertical orange/red line (see below for examples). If you see such lines, you need to check the marked locations in the 5-min pulse wave carefully. Sometimes body movement or coughing may also cause pulse irregularities. But if if you see early contraction pulses,(comparing peak-to peak intervals in the neibouring peaks), delayed contraction pulses, or skipped pulses, you should show the test data to your physicians. If you send the test data to us (pressing <Share> in the upper right corner of the Data page), our expert panel will examine the pulse waveforms in detailand determine the types of irregular heartbeats (first 10 reviews are free). Test a few times each day. Test more often when your prescription drugs are changed.
  • Why ANSWatch-Mini seems to be more expensive than most smart watches?
    It is our intention to keep the pricing of ANSWatch-Mini affordable and competitive. The reason for seemly-higher-than-most-smartwatch-pricing is manifold: (1) It is a certified/licensed/granted medical device (US FDA, Taiwan FDA, European CE, ISO 13485, GMP, etc.) (2) It employs several proprietary tecnnologies and IC parts (including patented, difficult-to-fabricate biosensors embeded in the wearing cuff) (3) The final design combines the functions of (a) an electronic blood pressure meter (b) a heart rate variability (HRV) analyzer (whose measurement is a golden standard for the testing of the autonomic nervous system), and (c) detection of irregular heartbeats (cardia arrhythmias) using an ECG. (4) Artifical intelligence (AI) have been employed throughout the device design and post-test data interpretation. We currently offer free shipping and handling.
  • How long does it take to conduct an ANSWatch-Mini test?
    About 6 minutes, Either sit-down or lying-down posture; Use the yellow soft pillow (included in the product package) to support the wrist. Do not move or talk during test.
  • Do you offer money-back guarantee if I am not satisfied with your product?
    Yes. We offer 10-day money-back guarantee. No questions asked. Please refer to <Shipping and Return> section.
  • Can I test ANSWatch-Mini independently without subcribing to your consultation service?
    Yes. Most customers do not need consultation. Customers are suggested to read the user's manual and watch demo videos for product introduction and test operation. If they still have questions, they can send the test data to our expert panel by pressing the button <Share> on the <Data> page. Our email address is Upon receiving the test data, our experts (consisting of bioengineers and physicians) will review the test operation and help to analyze the test results. This service is free for up to 10 tests (per unit). Charge-based consultation service (at $10 per review) is also offered.
  • How do I know if I have imbalance in the autonomic nervous system (ANS)?
    ANS has two branches - the sympathetic nervous system and the parasympathetic nervous system. Both branches are in a balance state under restful conditions. Dysautonomia (or imbalance in ANS) can be a mild temporary condition or a serious long-term illness. The most common symptom is being unable to stand up without feeling dizzy or fainting. Doctors call this orthostatic hypotension. Other dysautonomia symptoms include: Abnormally fast or slow heart rate Anxiety Excessive sweating or not being able to sweat Fatigue Feeling short of breath (especially when you exercise) Feeling thirsty all the time Having trouble swallowing Headaches Insomnia Nausea and diarrhea Vision problems (blurred vision, vision loss, tunnel vision) ANSWatch-Mini measures heart rate variability (HRV) and obtain ANS related parameters (as defined in the 1996 International HRV Standard**) in which HRV is associated with the total ANS activity (i.s. the effectiveness of the physiological control), LF with the activity of the sympathetic nervous system, HF with the parasympathetic nervous system, while LF/HF with the balance of the two branches. Each of these parameters has normal ranges that are dependent on the sex and the age. The test results on your smarphone will rank each parameter by AI (too high, high, normal, low, too low, etc.). You should watch these HRV results on daily or monthly bases, especially if you have some of the above symptoms or you are under medication. Talk to your doctors about your test results.
  • What health issues ANSWatch-Mini wrist monitor is most useful for?
    (1) Detect and monitor your irregular heartbeats IRRHBs (follow your physicians' instructions, or simply conduct frequent tests on a daily basis to catch IRRHBs. Show your results on your smartphone to your physicians (2) Monitor your current state of the autonomic nervosus system (ANS). When you are healthy, your heart rate variability (HRV) parameters are close to normal values (based upon your sex and age). HRV parameters tend to deviate from normal ranges when you are under stress, having sleep disorder, or getting sick. Your prescription drugs may also interfere with ANS functions. Show your test data to your physicians. (3) Check you blood pressure (systolic pressure SYS and distolic pressure DIA) and heart rte (HR) as often as instructed
  • What smart phones are compatible with ANSWatch-Mini?
    Most smartphones in the maket are compatible (iPhone, iPad, Android phones, tablets, etc.). ANSWatch-Mini is NOT compatible with Windows OS or Apple Mac OS devices.
  • Is ANSWatch-Mini a medical device?
    Yes. It has been granted by US FDA (prescription and over-the-counter OTC), It is also licensed by Taiwan FDA. It has been certified for ISO 13485 (international medica device standard), GMP, and CE Mark (EU)
  • Do you provide assistance for device operation and test data interpretation?
    Yes. Customers can send the test results to us via email utility in their phone or tablet. Our email address is We have an expert panel to first check correctness of device operation and then analyze the test data. The first 10 reviews are free. Most customers will have suffficient training and knowledge for ANSWatch-Mini during free review periods. After the free review period, a charge-based service ($10 per test review) is available for any customer who would need such consultation. Live chat is also available upon request.
  • Can I export test data to my own email, physicians, and consultants?
    Yes. On the <Data> page, find and press <Share> button to send out the email containing your test data. You may need to input age (birth date) and sex (plus any comment) so that the experts can review and rank your body parameters properly. To send the test data to our expert panel,the email address is:
  • Why experts who review my test data need my age and sex information?
    Many of ANSWatch-Mini measured physiological parameters are dependent on age and sex. Thus, ranking and advice (and AI) needs these values.
