I’ve been testing health tech for over a decade now and have always been fascinated by the insights tech can provide into my health. In 2025 I doubled down, took it to TikTok to test the format, before formalising my testing process
Health tech specialisms:
Within health tech I focus particularly on diagnostics, wearables, trackers and hormone health, with an accidental side gig on electrolytes and other supplements (long story). I focussed firstly through practicality: at-home diagnostics and digital tools are highly accessible, affordable and fairly quick to test in practice, so the barrier to entry is low. That’s important to me as the products I’m testing are either paid for out of my own pocket or occasionally donated/discounted by the kind folks at the brands in question, and there’s a limit to what people are willing to share for free. That said, I’m open to other areas and expect that this will expand in the future, and I’m particularly interested in exploring mental health tech next; anything non-pharmaceutical that can take the edge my life-long anxiety and depression would be something I’d take seriously, e.g. Neurosym, Flow Neuroscience, etc.
The perspective of my reviews:
Across products and services, my expertise is formed both from my day job (and, honestly, passion) at ThreeTenSeven. That means my lens is one of high-level product strategy, positioning, brand, messaging and marketing, as well as user experience and behaviour change effectiveness. I’ve worked with health brands such as Meril, Bayer, NHS England, Psyomics and OpenEHR, on brand positioning and wider GTM strategies, so see what works on client and vendor level.
Beyond work, I take my own health seriously, mind and body. I’m health literate but not health-trained, have used wearables forever as I love deep insight into my health, and my primary goals are longevity, great mobility/quality of life and, ok fine, aesthetics. Sidenote that I’m also busy at work so can be time-poor and lack the space to focus on complex onboardings and interventions that need too heavy a time commitment.
Where health tech products fail: meaningful, singular differentiation
My work experience plus life experience means I form uniquely critical opinions and contrasts on what works well—fast. On how brands are positioned in market, how effectively they communicate with users, how they onboard them, and how the UX helps adherence and behaviour change.
My key takeaway? That health tech businesses mostly fail not due to poor product effectiveness, but because they fail to communicate the problem that they’re solving. They don’t truly distil their unique proposition and single (yes, single) key point of difference, then adequately and consistently convey that in everything from product to marketing. And, PS, that’s what the effective ones get right—in health tech as with every brand. Convey that singular meaningful differentiation though and you will not just sell, but also retain, and build an army of ambassadors with it.
Stand-out products in health tech:
Having robustly tested a whole heap of health tech innovations, there are so few products and services that will actually make my must-have list for the long term. But as mentioned above, the ones that do aren’t just great products, but also great brands. Brands that communicate the need, the solution, and their product/person fit.
What I’ve ‘officially’ tested so far:
What I’ve ‘officially’ tested so far—meaning products I’ve taken through my full review process—cuts across the core pillars of health tech. That includes wearables like Apple Watch, Oura and Whoop that promise constant self-quantification; in-clinic diagnostic Neko, aiming to redefine preventative health; and at-home testing services including Hertility, Hormona, Vitl and Zoe, which bring complex biology into everyday reach. Let’s not forget femtech products like Elvie and Daye, alongside mental wellbeing apps like Headspace and Calm.
What’s coming:
The first season of reviews is in post-production currently and will launch on YouTube in May 2026, with new reviews following monthly from June. The first season includes frank, behind the scenes reviews of Elvie’s pelvic floor trainer, Neko, Vitl, Hormona, Hertility, as well as electrolyte brands Vidrate and Good Salt. I’m hoping they’ll spark some debate, inspire people to give a new health tech intervention a go, and maybe even piss a few people off… Not for the sake of it, but because if you’re not hearing where you can improve your product, you’re not learning. So all of it done with politeness and decency, with the goal of progress in mind.
Getting involved in Rachel Reviews:
I’d love to chat to anyone who building or buying in health tech, who’s got a perspective, a question, or a product or service that’s a big deal in health. Follow along on LinkedIn and YouTube and get in touch with me via LinkedIn.
