Support that sounds like you.
Choose a quiet Log, or turn on Coach for feedback. In Coach, five styles offer different kinds of encouragement. You can change your mind any time.
Gentle guide
Reassurance, small steps, and permission to rest.
Lunch is logged. If it helps, notice how your energy feels this afternoon. Nothing else is needed.
Steady partner
Practical habits and encouragement without pressure.
Lunch is logged, and it is another steady one. Keeping an easy lunch option ready makes busy days simpler.
Data coach
Patterns, uncertainty, and thoughtful experiments.
Lunch is logged as an estimate, about 600 to 700 kcal. Two more comparable days will show your lunch pattern.
Training coach
Training consistency, technique, fuel, and recovery.
Lunch is logged. Good fuel a few hours before training; plan to eat again after your session.
Direct accountability
Clear next steps and honest follow-through, without shame.
Lunch logged. Protein is light today. Add some at dinner, or leave it?
Shared boundaries
Every style respects your body, supports regular nourishment and recovery, and avoids shame, punishment workouts, or praise for severe restriction. A direct coach gives clear next steps, never harsher weight-loss targets. Missing journal entries do not prove that you skipped meals.
These are product styles, not clinically validated therapies or medical professionals. We do not diagnose eating disorders or prescribe personalized calorie deficits. If tracking is making eating or body worries harder, we can keep responses neutral; a qualified professional can help you decide whether tracking is useful.
What informs the approach
Our style design draws on the NIDDK’s guidance on small, practical habit changes and coping with setbacks, and the CDC’s guidance on activity and muscle strengthening. The five personas are Neutrino’s design choices; these organizations do not endorse them.
Our shared safeguards follow the NIMH’s description of eating-disorder concerns across body sizes and NICE’s guidance on restriction, compensatory behaviors, and when professional care is needed. Automated checks can miss things and can be wrong; Neutrino is not a medical or emergency monitoring service.
You control the contact
A persona changes the wording and focus of an optional daily check-in, not how often we text. Requested reminders are separate and work in Log or Coach. You choose their time and recurrence. Reply STOP to turn off texts, or cancel individual reminders in Your profile.
