What Is Refyuel Health OS?
An introduction to Refyuel and Health OS - the training-first fitness app that combines workout logging, nutrition tracking, lifestyle Habits, and weekly progress in one daily loop.
In short
Refyuel Health OS is a mobile fitness app from Refyuel Innovations that combines workout tracking, calorie and macro logging, lifestyle Habits, and weekly progress review in one place for Android and iOS. It is available on the App Store in Australia, Canada, India, New Zealand, the UAE, the UK, and the United States, with more countries planned.
Refyuel builds practical fitness software for people who train regularly and want their food logging — and lifestyle Habits — in the same daily loop - not scattered across five different apps.
Health OS is our first mobile product: plan workouts, log sets, track meals and macros, check in on Habits, and review your week without switching tools.
Who Refyuel is for
Health OS fits:
- Beginners building a gym habit who need structure without clutter
- Regular lifters who want set history, templates, and macro logging together
- Anyone tired of two-app workflows where training and nutrition never meet in one review
We are not building a social network or a content feed. We are building a daily operating system for training, nutrition, and Habits.
What Health OS includes
| Area | What you get |
|---|---|
| Workouts | Templates, set logging, rest timers, Warmup / Main / Cooldown structure |
| Nutrition | Food search, meal logging, calorie and macro progress |
| Habits | Daily lifestyle check-ins, streaks, and guided programs |
| Progress | Session history, personal records, weight trends, workout frequency |
| For You | Tips, wins, and a simple weekly view |
You can use workouts only, nutrition only, Habits only, or combine them when you are ready for the full loop.
How Refyuel is different
Most fitness apps pick one lane:
- Gym apps that ignore calories
- Calorie apps that treat training as an afterthought
- All-in-one apps that feel bloated on day one
Health OS is training-first with nutrition and Habits built in - because strength, body composition, and energy all respond to the same weekly signals.
