Mathew Beale

MSc Biotechnology, University of Reading

I’m Mathew Beale, the founder and developer of FitTools. My professional background is in software development, enterprise software sales and startups, including experience as a founder. I also hold an MSc in Biotechnology from the University of Reading.

I’ve spent much of my career building, working with and commercialising technical products. My biotechnology studies reflect a broader interest in health, science and technology, which ultimately led me to start building FitTools.

Outside of work, I’ve been involved in strength training and general fitness for many years, alongside kickboxing, calisthenics, running and wakeboarding. I also use fitness and recovery data extensively myself, which has influenced FitTools’ focus on measurements, trends and useful context rather than isolated numbers.

I built FitTools independently and continue to design and develop the platform. The goal is to create more than a collection of calculators: an evidence-first fitness and health ecosystem where your data works across the platform. Workouts, measurements, performance tests and health markers should connect, helping you measure where you are, understand what the numbers mean, track how they change and make better-informed decisions about what to do next.

How tools are reviewed

• Formulas are implemented exactly as published, with automated tests locking each one to worked examples before release.
• Where sources disagree, the page says so and explains which version is used and why.
• Every calculator names the sources behind it, in full; 43 are currently live.

Pulse

Pulse cards are drafted mechanically: a model summarises a published abstract, and the citation, figures and study details are taken from the source record rather than written by anyone. They go live as they are drafted, so no card waits on me before it publishes.

I read every one after it does. Where a card has misread its paper or overstated it, it is retired — a card can be pulled from the feed in a single change, and that is the check that makes reading them worth anything. What I am not doing is re-reading the underlying papers, so treat a Pulse card as a pointer to research, not as a verdict on it; every card links the study it came from so you can go and look.

If a number or a citation here is wrong, tell me and I will fix it. The same address takes source queries, partnership and press, and anything about your own data. Contact. What I cannot do by email is interpret your results or advise on symptoms.
