About this app

Nutrinaut is a peak performance coach that turns your training, nutrition, and daily signals into clear, day-to-day insights - so you know when to push, when to recover, and how to fuel consistently.

Set a goal (get in shape, lose weight, or gain muscle), create a plan, and use Insights to stay aligned with your body and your schedule.

Insights that guide your day (core)

Nutrinaut connects to Health Connect (optional) to power your main coaching features:

- Strain - daily workload using Steps plus active/total calories (includes a 10k steps challenge)

- Recovery - readiness signals using Resting heart rate (RHR) and VO2 max trends, plus supporting signals like sleep and SpO2

- Stress - stress level charts and guidance using Heart rate, RHR, and HRV (RMSSD)

- Sleep - sleep analytics using sleep sessions and sleep stages, with optional heart rate and SpO2 context

- Bio Age - a performance-oriented score shown in-app (top-right) based primarily on VO2 max and SpO2, with RHR as a supporting signal

Each Insights screen includes an explanation (for example, “Inputs used today” / “Why this score”) so it’s clear which metrics contributed.

If you choose not to connect Health Connect, Nutrinaut can still be used for logging and plan tracking, but Insights features run in limited mode because key signals (HRV, RHR, VO2 max, SpO2, sleep, steps) are not available.

Training + nutrition, in one place:
- Log workouts to track consistency and workload
- Track calories and macros against your plan
- See daily targets and progress

Meal logging (optional, secondary)

Log food in the way that’s fastest for you:
- Photo meal logging for macro estimates (calories, protein, carbs, fat)
- Quick manual entries when you already know what you ate
- Edit any entry to match a label or your portion

Personalized setup:
Nutrinaut uses your profile details (such as height, weight, and goal) to calculate your plan and daily targets.

Ratings and reviews

Ok i came across this application on reddit in a vibecoders subreddit. This is genuinely one of the best applications I've come across! No to mention its genuinely USEFUL!!! Props to the dev/s! for real! I dont generally pay subscriptions for applications...You guys deserve it here! ive used a TON of these types of applications...youve wrapped up everything useful across a large base of apps, and added an interpretation layer with AI that makes the insights ACTUALLY actionable! Seriously Good!

three days isnt enough time to review this app and make a decision. looks promising but honestly 3 days seems like a pressure tactic to "hurry up and buy!"

Required to sign up for 3-day trial and automatic subscription before you can even look at the app UI or see if you want to use it. They have X buttons to close their subscription ads but they go in a loop to the same subscription push.
