The check-in
Weekly, one screen: your trend, what your real expenditure looks like, and a small, safe target tweak you approve. 30 seconds.
Built to adapt
It grows with you, not against you.
The depth is algorithmic, not “more AI” — so it’s fast, calm, and yours. The free tier stays generous; Premium adds the adaptive layer.
Adaptive targets
Your numbers adjust to your real metabolism from intake + weight trend — capped for safety, always with a clear “why”. Premium
Weight & trend
Log a weight; we smooth out the daily noise so you see the real line, not the scale’s mood. Free
Repeatable logging
Saved meals, copy a day, quick-add, recents — and type # to drop a saved meal into your sentence, tweaked in plain words. Free
Day rhythm
After a few days, Today learns your usual meal times and sketches them as gentle invitations — pure statistics from your own logs, with an off switch. Free
Calm nudges
At most one suggestion at a time, number first, always dismissible. Push and in-app are one object — dismiss either, both clear. Free
Planning
Templates, “build the rest of my day” toward your targets, and a grocery list from your plan. Premium
Plate estimates
“What’s on this plate?” Snap a photo for ingredients and an estimate — log it in one tap, or don’t. 2 scans/day free, 10 on Premium. Free + Premium
Health-app sync
Import weight and steps from Apple Health or Health Connect, and export nutrition back — opt-in, on-device. Free
Cycle-aware (opt-in)
Phase overlay is free; Premium reads normal luteal water-weight as what it is, so your review stays calm instead of overreacting. Encrypted, never shared. Free + Premium

FAQ
Questions, answered plainly.
How do I log food?
Type or say it, like you'd text a friend: "two eggs, toast and an apple after the gym." Nutians extracts the foods, matches them against USDA and Open Food Facts, and shows each item as an editable entry. You can also scan a barcode.
What if the AI gets something wrong?
Every entry is editable — quantity, food, or the macros directly. If you state macros yourself ("a yogurt with 20 g protein"), we use your numbers. Corrections can be remembered, so the same food resolves your way next time.
What if it doesn't recognize a food?
It still shows up — as an entry flagged for your attention with zero macros, never silently dropped. Tap it to fill in details.
Can I log past meals?
Yes. Swipe back on Today to open any past day and add what you forgot — retro-logging is first-class, never guilt-framed. "Yesterday's dinner was…" works too; days recalculate automatically, in your timezone.
Do I have to weigh everything?
No. Sensible portion defaults apply when you don't specify; you can always tighten a number later. Rhythm beats precision.
Do I have to retype meals I eat often?
No. Type # in the composer to drop a saved meal into your sentence — "#chicken bowl but quinoa instead of rice" re-scores only the change and shows the diff. You can also copy a whole day or a single meal forward, quick-add macros when you already know them, and build custom foods and simple recipes once and reuse them — all free.
