Why Evidence-Based Research is Crucial for Health Tech Products — Even Lifestyle Apps
Whilst working with a stealth start up recently we found in early stage research with potential users that they wanted evidence based content. There was some pushback on this as it was contra to the model the business was putting together. However I feel strongly that regardless of whether users demand it or not, we should, when building health tech products go after the facts!
Health technology is transforming how we manage our wellbeing. From fertility tracking to sleep optimisation and autoimmune condition management, lifestyle-focused health apps are booming. These products often promise users greater control over their health through data-driven insights and behaviour change. Yet, as this sector grows, a critical factor is sometimes overlooked: the necessity of evidence-based research.
Whether an app is supporting women’s menstrual health, guiding dietary choices, or helping users manage stress, scientific rigour is not just for clinical devices or pharmaceuticals. Lifestyle-oriented health products can have a profound impact on user behaviour, mental health, and even medical decisions. Without a foundation in credible research, these products risk misleading users, eroding trust, and in some cases, causing harm.
Lessons from the Leaders: How Flo and Others Prioritise Scientific Validity
Take Flo, one of the world’s leading period and ovulation tracking apps. Flo didn’t achieve success simply by offering a clean interface or helpful reminders. It built credibility by incorporating medical expertise and conducting research into its predictive algorithms. The app collaborates with health professionals, gynaecologists, and data scientists to improve the accuracy of its cycle predictions and insights.
Clue, another respected menstrual health app, is similarly driven by science. It has partnered with academic institutions and published research on menstrual cycle patterns based on user data. By blending personal insights with peer-reviewed research, Clue empowers users without compromising scientific integrity.
In the sleep and mental wellness sector, apps like Headspace and Calm integrate clinical research into their product development. Headspace, for example, has conducted randomised controlled trials (RCTs) to validate the effectiveness of its meditation practices in reducing stress and improving focus.
Why This Matters: Lifestyle Choices Are Health Choices
It is tempting for startups to position their products as simple “lifestyle solutions,” exempt from the rigour of clinical testing. However, for users, lifestyle changes are deeply tied to their health outcomes. An app that claims to help manage autoimmune conditions, for example, is not simply offering convenience—it may influence users’ decisions on medication, diet, and stress management.
Misleading or anecdotal claims can lead users to:
- Abandon necessary medical treatment
- Follow restrictive diets that harm their health
- Experience heightened anxiety or confusion when outcomes differ from the app’s promises
The consequences can range from mild inconvenience to severe health complications.
Building Trust Through Evidence
Consumers are increasingly savvy. They expect health products to demonstrate credibility, and trust is easily eroded by vague claims or anecdotal success stories. Companies that invest in clinical validation, partnerships with medical professionals, and transparent data practices are best positioned to thrive long-term.
Some principles for startups building lifestyle health tech apps:
- Consult Medical Experts Early: Involve healthcare professionals in the product development process.
- Validate Claims with Research: Conduct user studies or collaborate with research institutions.
- Be Transparent with Users: Communicate what is evidence-based versus anecdotal.
- Don’t Overpromise: Empower users with tools, but avoid implying your app can replace medical advice.
Final Thought
The future of health tech lies not in making unverified claims but in blending innovation with evidence. Whether improving fertility tracking, autoimmune symptom management, or mental health support, apps that marry lifestyle guidance with scientific rigour will earn user trust—and ultimately, drive better health outcomes.
Better health through better evidence. That is the gold standard every health tech product should strive for.
