At CES in January 2026, Eli Health announced an expansion of its Hormometer platform: saliva tests for testosterone and progesterone, designed to return results through a smartphone in about 20 minutes. The company invited pre-orders and said shipments would begin by the end of the first quarter. That deadline passed months ago. As of October 16, 2026, Eli’s product pages still direct visitors to a waitlist, while its website labels both tests “Coming Soon.”
There is a Hormometer customers can buy today, but it measures cortisol, the stress-related hormone Eli began offering in 2025. The distinction matters: an operational cortisol service demonstrates that the company can produce and sell phone-read saliva tests. It does not establish that its newly announced testosterone and progesterone assays are shipping, or that they perform as claimed.
What Was Announced, and What Can Be Bought
Eli’s January announcement described a three-hormone platform. The planned testosterone cartridge would estimate free testosterone, the small portion of the hormone not bound to proteins in the blood. The progesterone cartridge would track changes across the menstrual cycle, particularly the rise after ovulation. Both would use saliva and the Eli app rather than requiring a blood draw or a mailed sample. The initial shipping target was the end of March 2026.
| Hormometer test | Status on October 16, 2026 | What is substantiated |
|---|---|---|
| Cortisol | Available to order | A consumer product is offered for sale; Eli reports laboratory benchmarking for its cortisol assay. |
| Testosterone | Waitlist / “Coming Soon” | Product specifications and a planned saliva-testing method are published, but routine consumer shipping is not established. |
| Progesterone | Waitlist / “Coming Soon” | Eli advertises a laboratory correlation figure, but the test is not shown as generally available for purchase. |
The current testosterone and progesterone pages have a “Join waitlist” button rather than a regular checkout option. That does not rule out prototypes, demonstrations or limited access. It means there is no clear evidence on those pages that consumers can place a normal order and receive either product. Eli has not explained the missed shipping target in the cited material, so a reason for the delay should not be assumed.
Why Testosterone and Progesterone Are the Interesting Additions
Cortisol already has an established role in Eli’s system. The newly proposed assays would take the platform into two different areas of hormone monitoring.
Testosterone changes over the day and is involved in sexual function, muscle maintenance and other aspects of health. Eli proposes measuring free testosterone in saliva, with its product page recommending roughly weekly morning testing for adult men. That differs from the usual clinical workup for suspected testosterone deficiency, which begins with reliable serum total testosterone measurements, repeated on separate mornings, and additional testing when appropriate. A home trend could be interesting to someone comparing sleep or training periods, but its readings would need to be shown to correspond consistently with appropriate reference methods before they could inform medical care.
Progesterone generally rises after ovulation during the second half of a menstrual cycle. Eli proposes testing saliva at several points in the cycle, letting users see that pattern without arranging repeated laboratory appointments. Its progesterone page recommends at least four tests per cycle and describes a roughly 20-minute result. For someone trying to understand cycle timing, the practical question is whether the test can reliably detect the relevant change across different users and cycles, not merely whether progesterone can be measured in saliva in a laboratory.
The company portrays these measurements as a way to study relationships between hormonal changes, sleep, exercise and symptoms. Those are prospective uses of the announced products, not demonstrated health benefits from a product already in broad consumer use.
How Hormometer Compares With Tests People Can Use Now
Several home hormone-testing options already address parts of the same questions, although they measure different substances and answer different questions.
Clearblue Advanced Digital Ovulation Test measures luteinizing hormone (LH) and a urinary estrogen metabolite to identify fertile days. It provides an immediate home result, but it predicts the fertile window rather than measuring progesterone directly. Proov Confirm tests urine for pregnanediol glucuronide (PdG), a breakdown product of progesterone, to help assess whether ovulation has occurred. Both are existing approaches to cycle monitoring. Eli’s proposed progesterone test would be distinct because it aims to measure progesterone itself in saliva and display successive readings in an app.
For testosterone, mail-in laboratory services offer a different trade-off. Everlywell’s Men’s Health Test, for example, uses samples collected at home, including a finger-prick blood sample and saliva, which are then analyzed by a laboratory. That avoids a clinic visit for collection but cannot deliver a readout on the bathroom counter in 20 minutes. A rapid saliva test would therefore address a real convenience gap—if it becomes available and its performance is adequately documented.
These products should not be compared by speed alone. LH, PdG, salivary progesterone and blood testosterone are not interchangeable measurements. A person choosing a method needs to know whether the goal is predicting ovulation, identifying a post-ovulation change, or investigating a potential endocrine disorder.
What the Accuracy Evidence Actually Covers
Eli advertises 97% accuracy for its commercially available cortisol test against a laboratory reference method. Its progesterone product page claims 94% correlation with a laboratory reference in third-party studies. Those descriptions are company-reported. Correlation is not the same as accuracy: two methods can track one another while giving systematically different values. The public-facing figures alone do not provide the sample sizes, error ranges, performance across low concentrations or full protocols needed to evaluate the planned progesterone product independently. No comparable publicly documented consumer-validation dataset for Eli’s testosterone device was established in the sources reviewed here.
There is independent science on measuring hormones in saliva, but it must be identified correctly. In a 2026 study in Psychoneuroendocrinology, researchers compared laboratory approaches to salivary progesterone and estradiol across four laboratories and 336 samples or quality-control specimens. The progesterone methods followed menstrual-cycle changes, but some immunoassays gave higher concentrations than mass spectrometry and suggested a daily decline not seen with that reference technique. The study illustrates why the analytical method matters. It did not test Eli’s Hormometer cartridges or smartphone-reading algorithm, so it cannot validate their advertised performance.
For medical decisions, the boundary is specific. Eli markets Hormometer as a wellness product, not a diagnostic service. The Endocrine Society recommends repeated morning blood testing when assessing men for testosterone deficiency. The American College of Obstetricians and Gynecologists advises against using salivary hormone testing to tailor compounded menopausal hormone therapy. App readings should not be used to start hormone treatment, change a prescribed dose or diagnose an endocrine disorder.
The Product Available Today Is Still Cortisol
Eli’s cortisol test collects a saliva sample, uses a disposable test and lets the iPhone app analyze the result from an image. The company says readings take around 20 minutes. On its US product page, an eight-test one-time package is listed at $129 plus shipping; subscription options include eight tests for $99 a month and 24 tests for $199 every three months. Eli describes the app as available on iPhone, with Android support still planned. Prices and availability may change.
Those details provide a more grounded view of the platform than a demonstration at a technology show: the system involves ongoing disposable-test purchases, a compatible phone and deliberate sampling. It is not a wearable that continuously measures hormone concentrations. For cortisol, people can buy supplies and repeat measurements across mornings and evenings. For testosterone and progesterone, the company has described the intended experience but has not shown ordinary retail fulfillment on its product pages.
The most consequential Hormometer story in October 2026 is therefore the gap between the expansion announced in January and the products actually on sale. Faster access to repeated testosterone or progesterone measurements could make longitudinal tracking easier. Before that proposition can be assessed in real households, Eli needs to move beyond waitlists and provide sufficiently detailed, product-specific validation of the new assays.
