Nutrition
Reimagined.
Speak it, snap it, or type it. Lio is an AI nutritionist that learns the way you actually eat — and remembers — so tracking finally feels like living.
One app. Five surfaces. Zero friction.
Speak, snap, or type.
“Large bowl of pasta with pesto and pine nuts.” Or a photo. Or a quick note. Lio gets context, ingredients, and portions instantly.
AI Nutritionist Chat
Ask “how's my protein this week?” and Lio reads your real logs to answer. Streaming replies, inline confirmation cards, and menu-photo guidance — every turn in the context of what you've logged.
Streaks & Celebrations
3, 7, 14, 30, 60, 100. Daily wins, perfect days, and milestone moments worth marking.
Weight Trends
Selectable trend windows — two weeks to your whole log — with a goal pace that projects your ETA.
Health Sync
Apple HealthKit and Android Health Connect. Activity meets nutrition without spreadsheets.
Macro Precision

It remembers.
So you don't have to.
Every meal, chat, and weight entry becomes a dated episode — and the asides you drop while logging (“allergic to peanuts,” “training for a marathon”) stick too. Lio distills it into evidence and only surfaces an insight when the pattern is real.
