We would not buy the Fanyil TrackPro 2.0 for blood sugar: the FDA has authorized no such watch, and the seller’s fine print calls the readings reference only.
We read the product page, the policies and the page code, compared the needle-free promise with the FDA’s published warning, and traced the same watch name across other websites.
Overview
What the page offers
The Fanyil TrackPro 2.0 is a square smartwatch listed at $49.99 against a crossed-out $99.98, on a general store that also sells clippers, jigsaw puzzles and hummingbird feeders.
Its pictures promise painless blood sugar measurement with no needle, and the first picture adds lipids and uric acid to the list of things the watch supposedly tracks.
The text of the listing is much more careful, because it admits that the measured data is for reference only and cannot be compared with medical grade products.
What we found behind the page
The FDA has not authorized, cleared or approved any smartwatch intended to measure or estimate blood glucose on its own, and its notice warns consumers not to buy one.
The crossed-out $99.98 has been in place since at least May 2025, it is exactly twice the sale price, and every crossed-out bundle total is a multiple of $49.99.
The same text and prices appear under three brand labels created within nine minutes, and the watch name is also sold on other sites with different specifications.
What we could and could not verify
Here is where the evidence stands after our checks:
- Verified by us: the FDA text, the price history, the bundle arithmetic, the policy wording, the listing timestamps, the domain records and the absence of any approval claim.
- Not found: any certificate, test result, named manufacturer, countdown timer, low-stock alert or registry record for the company names on the store.
- Not verified: delivery, refunds and the real accuracy of the watch, because we did not place an order or test one.
Our advice is not to rely on this watch for glucose readings, and to read the response section below if you already ordered.
What the FDA Has Published About Glucose Watches
Before judging the page, we opened the FDA’s safety communication, Do Not Use Smartwatches or Smart Rings to Measure Blood Glucose Levels. It is dated February 21, 2024.
The communication warns about watches and rings that promise to measure blood sugar without piercing the skin, and it separates them from apps that only display data from authorized sensors.
It then makes a plain statement: the FDA has not authorized, cleared or approved any smartwatch or smart ring intended to measure or estimate blood glucose values on its own.
The same page adds that these devices do not directly test blood glucose, and that they are made by dozens of companies and sold under multiple brand names.
Its advice to consumers opens with a plain instruction: do not buy or use. It adds that such devices may be sold directly from the seller.
The stated danger is practical. Inaccurate readings can lead people with diabetes to take the wrong dose of insulin or other medicines, with low blood sugar as a possible result.
We then searched the Fanyil product page and every policy page for any sign of approval, such as FDA, CE, FCC, clinical testing or a certificate number.
We found none. The only phrase from our list is medical grade, in a disclaimer saying the watch’s data cannot be compared with such products.
That is better than a false approval, but it also means the store offers nothing that would tell a buyer why the readings should be trusted.
A Needle-Free Promise With a Disclaimer Underneath
We scrolled through the five pictures in the gallery, and they carry the promise that the page text avoids.
One picture is headed Lipids Uric Acid Blood Glucose Monitoring Smart Watch, and another reads Painless blood sugar measurement.
Two more carry the phrases Safe, no need to put needle and No need to give a needle.
Nothing in the written description repeats the lipid or uric acid promise, and no other part of the page explains how a watch could measure either one through the skin.
The only written statement about blood sugar sits in a question and answer block called Instructions for use, and it is worded very differently from the pictures.
The answer is brief: blood sugar and blood pressure can be tested, the watch must stay on the wrist during a reading, and the data is for reference only.
A buyer who looks only at the pictures sees a needle-free glucose monitor, while one who reads the answer sees a gadget whose numbers should not be relied on.
The listing also leaves out facts a health buyer needs. It mentions an instructions app with video tutorials but never names it, so there is nothing to look up.
We also noticed that the picture files carry the name Welnax, not Fanyil, so the images were probably made for another seller’s listing and reused here.
The terms add little comfort. Section 13 is generic wording, yet it means the store does not warrant that results from using its service will be accurate or reliable.
A 50% Discount That Never Ends
The crossed-out $99.98 invites a buyer to believe a sale is running, so we checked how long it has been there.
A copy from May 23, 2025 in the Internet Archive shows a regular price of $99.98, a sale price of $49.99 and the words Save $49.99.
A copy from August 14, 2025 shows the same figures, and the live page we captured on November 12, 2026 still shows them.
That is a sale price held for about eighteen months, so the $49.99 is the normal price and the $99.98 is a reference figure that nobody paid.
The arithmetic supports that reading, because $99.98 is exactly two times $49.99, and no other price for the watch appears anywhere on the store.
The bundle selector under the price repeats the pattern. We read its configuration in the page code and found five rows: one watch, two, three, four and six.
The BUY 2 row is selected when the page loads and carries a Most Popular badge.
A shopper who clicks Add to cart without touching anything would put two watches in the cart for $80.00.
The other rows price three watches at $105.00, four at $120.00 and six at $174.00, which works out to $35.00, $30.00 and $29.00 per watch.
The crossed-out totals next to those prices are $149.97, $199.96 and $299.94, which equal three, four and six times $49.99.
The labels Save 20%, 30%, 40% and 42% therefore measure each bundle against a multiple of the sale price, and the same $99.98 reference figure sits behind the whole ladder.
The page code also tells us what is missing. The bundle app has its timer switched off and its low-stock alert switched off, and the variant is marked as available.
So the Fanyil page makes no promise that stock is running out or that a deadline is near.
That kind of urgency lives on other pages that use the same watch name, as we show below.
The discount habit is store-wide. In the public product list, 154 of 417 listings carry a crossed-out price, with a median markdown of 47% and a maximum of 62%.
One Watch Under Several Names
We read the store’s public product list and found three TrackPro 2.0 listings with different brand labels: Fanyil, Funfany and Besspub.
Their text is identical, down to the same four questions, and each costs $49.99 against a crossed-out $99.98. Each listing also uses the same five pictures.
All three listings were created within nine minutes on April 28, 2025, starting at 00:37 UTC and ending at 00:46 UTC.
All three share one publication time, 01:16:02 UTC on September 17, 2026, which suggests a bulk republishing of the catalog and not a deliberate launch of each brand.
The store is the same one we described in our earlier article on Shiorey and its 38 brand labels, where this watch is one of many repeated listings.
The watch name also travels beyond this store. A search led us to outfanytrackpro.net, which sells an Outfany TrackPro 2.0, and to a second site, outfanytrackpro.com.
Those domains were registered on January 24, 2025 and July 1, 2024, at two different registrars, and both use Cloudflare name servers, unlike the Amazon name servers of fanyil.com.
We found no technical link between those sites and the Fanyil store, so who runs either one is unknown. All we can show is that they sell the same name.
Their facts differ from Fanyil’s. The Outfany page lists a case of aluminum alloy and a 260 mAh battery, while Fanyil’s listing gives a zinc alloy case.
The prices differ as well, with the Outfany page showing a range from $99.99 down to $59.75 and options labeled 1x, 2x at 50% off and 3x at 60% off.
The money-back promise differs too. One Outfany page offers 30 days, the other offers 90 days, and Fanyil’s refund policy starts a 30-day clock at delivery.
A watch with one specification should not have three, and the FDA’s note about dozens of makers and multiple brand names describes this pattern closely.
A Sales Article Dated After the FDA Warning
The search that found the Outfany sites also led us to a long article on offer.outfany.com, headed Needle-Free and Pain-Free, with a byline date of February 28, 2024.
That date is seven days after the FDA issued its warning. The article nevertheless calls the watch a glucose monitor that makes blood sugar testing 100% pain-free.
It names a Glucose Monitor Chip, promises accurate glucose readings and suggests the device could actually save your life.
We tested those promises. The FDA notice explains that such watches do not directly test blood glucose, and the article offers no test, certificate or named engineer.
We also compared the date with the domain. Outfany.com was registered on April 12, 2024, more than six weeks after the date printed on the article.
The Internet Archive’s index lists no copy of the subdomain before May 13, 2024. A registration date proves nothing alone, but this one fits a date chosen for effect.
The price story does not hold together either. The body of the article announces $69.99 as a 50% discount, while a line near the bottom calls $99.99 the sale price.
The article is built like a news story, but its notice calls it an advertisement and not a news article, so the byline and date belong to ad copy.
Its urgency also contrasts with the Fanyil page. It insists the watch is selling out everywhere and the discount will not last, a pressure the Fanyil page never applies.
Reviews That Never Mention Glucose
The Outfany product page shows a rating of 4.87 from 1,172 reviews, which is the kind of number that makes a risky health product look settled.
We read the 22 reviews that the page displays. None of them contains the words glucose, blood sugar or diabetes, even though the product is sold as a glucose watch.
Three reviews mention blood pressure, and one of them regrets that the watch has no blood pressure monitoring, although the product text lists it as a feature.
The product text tells buyers to install an app called H-Band, yet none of the 22 reviews mentions it. Four refer to an app called Zepp and one to GloryFit.
Eleven reviews compare the watch with a Fitbit, Garmin, Apple Watch or Galaxy Watch, and one recounts a purchase on Prime Day, which is an Amazon shopping event.
One review recounts a replacement handled through Asurion, a protection plan provider, and another mentions a different model called TrackPro 3.
We cannot tell where those reviews came from, but their content does not match the watch described on the page. We would give them no weight for a health device.
The Fanyil page has none of this. It shows no rating and no reviews, so a shopper there has nothing to weigh except the pictures and the price.
Shipping, Returns and Warranty in Numbers
We read the shipping page and the refund page to see what a buyer could expect if the watch did not work as promised.
Orders ship free above $119 and cost $9.99 below that, so one watch at $49.99 costs $59.98 and the two-watch default at $80.00 costs $89.99.
The four-watch bundle at $120.00 is the cheapest row that clears the $119 line, which means the shipping rule rewards buying more watches.
Delivery is estimated at 10 to 15 business days for the United States, after 1 to 4 days of preparation and testing before shipment.
The refund policy gives 30 days from the delivery date on the tracking record, and the item must be unused and in the condition it arrived.
The buyer pays the return shipping, the cost is deducted from any refund, and the return address is only given after the buyer emails customer service.
Approved refunds go back to the original payment method within 1 to 3 days after the store receives and inspects the item.
The terms add a promise that all items carry a full one-year warranty, but they give no instructions for using it and the refund policy never mentions the warranty.
The FAQ allows order changes only within 12 hours, and the terms put any dispute under the laws of Hong Kong, far from a buyer in the United States.
The FAQ lists PayPal and Visa, Mastercard, American Express and JCB, and our capture shows a Pay with PayPal button, so a dispute through the payment provider remains possible.
Who Runs Fanyil.com?
The names in the documents
We found three different company names on the store. The About page names Fanyil-Bobbi Co., Ltd., and the Contact page names Bobbi Co., Ltd.
The terms of service name Fanyil International Limited as the operator of the site, and the footer adds that the store is powered by Fanyil.
The About page also promises that every Bobbi product is thoughtfully selected, which reads like text left over from another store that used the Bobbi name.
None of the three names comes with a registration number, a director or a city, apart from the postal address on the Contact page.
Where the Albany address leads
The Contact page gives the address 418 Broadway, Suite R, Albany, New York 12207, so we searched New York’s open data set of business filings for it.
The set lists 6,446 distinct filings at 418 Broadway, dated September 29, 2025 to November 9, 2026, and about 3,000 of them mention Suite R.
Roughly three in four name one of two registered agent companies as the place where legal papers are received, which is what a shared service address looks like.
We found no filing for Bobbi Co., Ltd., Fanyil-Bobbi Co., Ltd. or Fanyil in that data set, which covers recent filings only and is not the full register.
The store behind the domain
The domain fanyil.com was registered on January 6, 2024 through GoDaddy, and its record was last changed on January 6, 2026. You can check it with the ICANN lookup.
The page code identifies a Shopify store with the handle colapashop and shop number 55362846918, which also answers on a second domain described in our Shiorey article.
The public product list holds 417 listings under 41 vendor labels, and the theme on the live store is named like a time stamp, not like a brand.
The product page relies on a bundle app and a PayPal button, which are ordinary Shopify tools and reveal nothing about who owns the store.
What we could not confirm
We could not tie any of the three company names to a registered business, so we do not know who receives the money or answers for a problem.
We did not call the support phone number, place an order or test a watch, and we did not search a Hong Kong register for Fanyil International Limited.
A business directory lists a similarly named company at the Albany suite, but we did not confirm it against the New York register and do not rely on it.
Shared addresses, brand labels and platform details show a common setup, not proven common ownership, and we draw no conclusion about who is behind either the Fanyil or Outfany names.
What to Do Before You Buy or After You Paid
-
Do not use it for glucose. Never adjust insulin or other medicine based on the watch, because the FDA warns such readings may be inaccurate.
-
Keep a real meter. If you manage diabetes, ask your doctor or pharmacist about an FDA-authorized blood glucose meter or continuous glucose monitor.
-
Treat it as a cheap watch. If you want steps, sleep and notifications, buy a fitness watch from a seller that makes no glucose promise.
-
Ignore the sale label. The crossed-out $99.98 has stood for about eighteen months, so compare the $49.99 with other watches instead.
-
Watch the default bundle. The two-watch row is pre-selected, so check the cart quantity and the shipping line before you pay.
-
Save the evidence. If you already ordered, capture the product page, your receipt and the refund policy, and email support for a return within 30 days of delivery.
-
Dispute the charge. Ask PayPal or your card issuer for a refund, and send a card dispute letter within 60 days of the first bill with the error.
-
Report it. Tell the FDA through its MedWatch reporting form and file a report at ReportFraud.ftc.gov.
Frequently Asked Questions
Is the Fanyil TrackPro 2.0 a scam?
We cannot prove fraud, but a needle-free glucose promise, an unauthorized device class and a discount that never ends are enough reasons to skip it.
Can the TrackPro 2.0 measure blood sugar?
The FDA notice explains that smartwatches do not directly test blood glucose, and the listing itself calls the data reference only, so do not rely on it.
Is the 50% discount real?
No. The $49.99 price and the crossed-out $99.98 have stood side by side since at least May 2025, and $99.98 is simply twice the sale price.
Is Fanyil the same as Outfany?
We found the same watch name on both, but different domains, registrars, platforms and specifications, and nothing that proves a common owner.
Can I return it if it does not work?
You have 30 days from delivery, you must email first to get a return address, and you pay the return shipping, which is deducted from your refund.
Has the FDA authorized any glucose smartwatch?
No. Its safety communication confirms it has not authorized any smartwatch or smart ring intended to measure or estimate glucose on its own.
The Bottom Line
Do not buy the Fanyil TrackPro 2.0 for blood sugar: no approval exists for this class of device, the page contradicts its pictures and the discount never ends.
To track glucose, use an FDA-authorized meter or continuous monitor chosen with your doctor, and never change medication because of this watch.
If you already paid, save your receipt, ask for a return in writing within 30 days of delivery, and dispute the charge with PayPal or your card.
