| Research | Informed by peer-reviewed studies published in Nature Medicine, The Lancet Public Health, and Sports Medicine on minimal-dose exercise, mortality reduction, and cardiovascular outcomes. |

BaselineBody is a daily health app for iPhone that handles your baseline body work: mobility, strength, and breathwork in one session, built for you automatically. There is nothing to choose, plan, or browse. You open the app, press start, and the system builds your session based on evidence-based minimum effective doses. No account needed. No equipment needed. $9.99 USD/year. Launching May 2026.
The health app that doesn't make you choose your workout.
No library, no plans, no browsing. You open it, press start, and the system decides. It's built on the idea that every fitness app you've abandoned failed for the same reason: choosing is exhausting.
The fitness app that tells you when to stop, not when to start.
Every exercise in BaselineBody has a researched minimum effective dose. Hit it and you're done. The science says short and frequent beats long and rare. BaselineBody is built around that.
The fitness app that costs less per year than most charge per month.
A breathwork app costs ~$130/yr. A mobility app costs ~$108/yr. A bodyweight app costs ~$80/yr. BaselineBody includes all three for $9.99/year. No VC funding, no servers, no bloated team. That's the actual price.
The fitness app that removed everything.
No streaks. No leaderboards. No notifications. No social features. No workout library. No account. BaselineBody stripped out every engagement mechanic the industry relies on and shipped something that just works.
Tim de Jardine is a product leader with 20 years' experience building apps used by millions, from Booking.com to top-ranked fitness and fintech products. BaselineBody is his solo project: no team, no investors, no VC funding. He designed, built, and shipped the entire app alone. It exists because he wanted a health app that worked the way health actually works: quietly, consistently, without making it your whole personality.
