Health apps people actually stick with
Fitness, training, recovery, and wellbeing apps designed for behavior change, not just features. I've built running calculators, workout trackers, HRV and breathing tools, and a mental-health companion.
Why health & fitness
Health apps live or die on habit, trust, and clarity. I design the behavioral loop and the data display, and I ship the code — so the science and the interface are the same decision.
- Designed for habit and behavior change, not feature lists
- Clear, trustworthy display of personal and health data
- HealthKit, sensors, and real-time tracking handled
- From running pace to HRV to mental health — shipped
How a health app earns trust
Health apps live or die on habit, trust, and clarity. The process is built around all three.
Design the behavioral loop
Start with the habit: the trigger, the action, the reward, the return. Features exist to serve the loop, not the other way around.
Make the data trustworthy
Personal and health data displayed so it's instantly legible and never alarming — the difference between a user who trusts the app and one who deletes it.
Handle the hard integrations
HealthKit, sensors, wearables, and real-time tracking wired up properly, so the numbers are right and the app feels alive.
Ship and refine on real use
Built in production code and shipped, then tuned on how people actually use it — because behavior change only shows up in the real world.
Health & fitness questions
What founders ask before building a health or fitness product.
Yes — HealthKit, sensors, and real-time tracking are part of the build, not an afterthought. The interface and the data plumbing are designed together.
Running and pace tools, workout and training trackers, HRV and breathing tools, and a mental-health companion. Behavior-change products across fitness, recovery, and wellbeing.
The design and build are consumer and wellness focused. For regulated or clinical products we scope carefully and are upfront about where specialist compliance help is needed.
By designing the behavioral loop first — trigger, action, reward, return — and letting the feature set follow. Most fitness apps ship features; the ones people keep ship a habit.
