Meet your coach

Text it like a person.
It answers like it knows you.

because it does

  • Talks like a friend who happens to know nutrition

    Warm, direct, a little playful. It will never call food “bad” or you “off track.”

  • Answers with a plan, not a lecture

    Ask “what fits tonight?” and get an order, a number, and the one swap that matters.

  • Picks things up as you go

    Mention your Thursday spin class once. Next Thursday, dinner is already easier.

What Ferno remembers

A coach with a very good memory.

and a very good eraser

Most apps forget you the moment you close them. Ferno keeps notes — the goal, the tricky hours, the foods you won’t give up — and uses them every time it plans your day.

  • Wedding on Oct 24. That’s the mission.

    from day one

  • Dinner is the hard one — check in at 4:00.

  • Cooks most nights. 20-minute recipes win.

    from chat, tue

  • Pasta person. Keep it in the plan, not out of it.

    from chat, wed

  • Spin class Thursdays — wiped after. Plan an easy dinner.

    picked up, thu

  • Hates the phrase “cheat meal.” Never say it.

Every note has an ✕. Tap it and Ferno forgets for good — hard-deleted, not hidden. your memory, your rules.

FAQ

Fair questions.

asked around the fire
Is Ferno a diet?
No. Ferno doesn't hand you a meal plan or ban foods. It works out a daily calorie target from your goal and pace, then helps you hit it with the food you already like — pasta nights included.
How accurate is the photo calorie counting?
Good enough to steer by, and honest about it. Ferno breaks a photo into ingredients and portions, tells you how confident it is, and lets you tap anything to fix it. For packaged food or recipes you make often, save it once and it's exact from then on.
What does Ferno remember — and can I delete it?
It remembers what you tell it and what it learns from your logs: your goal and date, your tricky hours, the foods you love, what’s going on this week. You can see every memory in the app, and deleting one removes it for good. You can also delete your whole account and all of its data in one step.
Who sees my data? Do you sell it?
We never sell your data and we don't run ads. To coach you, your meals and messages are processed by our AI provider, Anthropic, under terms that don't let them train models on it. The full details are in our privacy policy.
Is this medical advice?
No. Ferno is a coaching tool for healthy adults, not a doctor or dietitian. If you're pregnant, have diabetes, a history of disordered eating, or any condition affected by diet, please talk to your healthcare provider first. Ferno is for people 18 and over.
Do I have to weigh myself?
No. The scale is optional and skippable from day one. If you'd rather go by energy, how clothes fit or photos, Ferno will coach you that way — zero drama either way.
How does the free trial work?
You get 3 days free. After that it's $24.99/month or $9.99/week, billed by the App Store or Google Play. Cancel anytime in your phone's subscription settings before the trial ends and you won't be charged.
iPhone, Android or web?
Ferno is built for iPhone and Android, and you can also use it in your browser. Your account and memories follow you across all three.
