About
A calculator that explains itself.
Operated from India · last revised 3 Sep 2026
ifit90 is a small, independent product built in India. A tested engine computes your numbers; a language model only explains what the engine already decided. One person is accountable for it, and their address belongs on this page.
What ifit90 is
ifit90 turns eleven answers into a 90-day fitness map: your calorie and protein targets, the problems your answers actually predict, twelve weeks of training matched to the equipment you own, an Indian meal template built from roti, dal, curd and whatever else you already eat, and ninety dated days you can import into a calendar. One payment of ₹99. No subscription, no account, no app to install.
The differentiator is boring and important: every number is computed and shown. The engine is deterministic and tested — the same answers always produce the same plan — and the writing is constrained to explain facts the engine already produced. Read the methodology for the formula chain and the source behind each constant.
Who operates it
Operator identity — to be completed before launch. The founder’s legal name, city, business entity, GSTIN if registered, and the registered address belong in this block. Indian consumer rules and payment-gateway onboarding both require a named, contactable operator, so a placeholder here is a launch blocker rather than a nicety.

Why it exists
Indian fitness advice online is mostly either a screenshot of an American calorie calculator or a coach charging ₹3,000 a month for a PDF. Neither knows what a katori of dal weighs, that 23 is the overweight BMI cut-off for Indians rather than 25, or that a plan for someone with two free evenings a week and no gym has to look different from a plan for someone in a gym six days a week.
So the engine was built around Indian data first: ICMR/NIN reference values, Asian-Indian BMI and waist cut-offs, a food table in household portions, real gym and grocery prices, and a festival calendar. The report is what a competent coach would write down on day one, if they had the patience to show their arithmetic.
Where the ₹99 goes
| Line | What it pays for | Approx. |
|---|---|---|
| Compute | The engine run, the fact packet, the calendar and the .ics | ₹0 |
| Writing | The language model that explains the computed facts | ₹4–6 |
| Payments | Gateway fee and tax on a ₹99 transaction | ₹3–4 |
| Hosting | Server, database and email, spread across every report | ₹2–3 |
| The rest | The time that went into the engine, the data and the writing | the rest |
There is no upsell, no supplement affiliate link and no coaching funnel behind this. If a page ever recommends something we are paid for, it will say so on the page.
What we refuse to do
- No diagnosis, no treatment, no prescription — this is not medical advice.
- No plan at all for anyone under 18, anyone pregnant, a BMI under 17, or answers that signal disordered eating. The intake stops, points at a doctor, and you are not charged.
- No “lose 10 kg in 30 days”, and no guaranteed outcomes of any kind.
- No supplements, no steroids, no extreme cuts, no detoxes.
- No selling your data, ever — see the privacy note.
