Network & Web tools and guides on Dailiyo — 2 entries.
Dailiyo is a free hub of calculators, converters and short, practical guides that handle the everyday digital chores most of us do without thinking — checking BMI before a doctor visit, working out the EMI on a loan, generating a strong password, converting an image, scaling a recipe for unexpected guests. Tasks that should take seconds, not an afternoon of fighting with popups.
Every tool runs in your browser. Nothing you type leaves your device, there is no sign-up, no monthly limit, no upsell. The site is funded by light, non-intrusive advertising — the same model that lets wikipedia-style resources stay free, applied to a tighter set of specific, useful tools.
We built the kind of site we wished existed when we needed to do quick maths or quickly convert something. If you ever wished a specific calculator or converter existed and could not find a good one, tell us via the Contact page — the most-requested ideas jump to the top of the roadmap.

The web is full of "free calculator" pages that bury the answer under five tabs of popups. We built Dailiyo on the opposite premise.
Calculators run entirely in your browser using standard web APIs. We do not log, store or transmit the numbers you type. The only data the server ever sees is anonymous page-view counts.
We use the formulas professional bodies recommend — Mifflin-St Jeor for BMR, the Navy circumference method for body fat, standard EMI amortisation for loans. Each tool's About section names the source.
A clean page with the tool you came for, a short explanation underneath, and a footer. The site is supported by a small number of well-placed ads — not interstitials, not autoplay video, not "subscribe for the answer".
Most readers reach Dailiyo from a phone in the middle of doing something else. Every tool is built to work in a single screen, with touch-friendly inputs, on a 4G connection.
No regional paywalls. The loan and currency tools work for any currency you enter; the unit converter handles imperial and metric; the land calculator handles katha and bigha alongside acres and hectares.
Every calculator is verified against at least one authoritative source and one independent implementation before publishing. When a recommendation changes (new BMI ranges, revised protein guidance), we rewrite the page rather than patch it.
Want to see how we pick formulas, write content and keep tools current? Read the Methodology page — and meet the team behind the work on the Editorial page.
A transparent look at our methodology and editorial standards.
Every calculator on Dailiyo starts with a published formula or a widely accepted clinical, financial or technical reference. We document that source on the tool's About section — for example, BMR uses Mifflin-St Jeor (1990), BMI thresholds follow the WHO adult bands, loan amortisation uses the standard reducing-balance formula, and body fat uses the U.S. Navy circumference method. If we cannot link back to a defensible source, the tool does not ship.
Articles go through a draft → editorial review → fact-check → publish workflow. A second editor reviews every article before it goes live. Health and finance pieces are additionally checked against authoritative bodies (WHO, CDC, ESC, NICE, FCA and the relevant academic source); technology and lifestyle pieces are checked for accuracy by a domain editor.
We review every tool at least once a year and update it whenever the underlying formula, regulation or guideline changes. Corrections are made promptly when reported, and significant changes are noted in the article footer so returning readers can see what shifted. Our full process is documented on the Methodology page.
We do not, under any circumstances, accept payment in exchange for editorial coverage. We do not embed third-party calculator widgets and re-skin them as our own. We do not buy "white-label" content packs. Every line of body copy on this site has been written by a human on the Dailiyo team.

Yes — every tool and guide on the site is free to use, with no sign-up, no per-month limits and no premium tier. The site is funded by light advertising rather than subscriptions or paywalls. If you ever hit a "pay to continue" wall, it is not from us — please email so we can investigate.
No. Calculations run entirely in your browser using standard JavaScript. The values you enter are not transmitted to our servers and are not saved anywhere — close the tab and the inputs are gone. The only data the server ever sees from a tool page is an anonymous page-view ping.
Every calculator uses the formula recommended by the relevant professional body (Mifflin-St Jeor for BMR, U.S. Navy circumference method for body fat, standard EMI amortisation for loans, etc.). Each tool's About section names the source. Results match those references to the precision the formula supports — typically within 1–3% of any other implementation of the same formula.
They are general-purpose tools, not professional advice. The Health calculators are a starting point, not a diagnosis — for anything affecting medical decisions, consult a clinician. The Finance calculators do not replace a qualified financial advisor. The Disclaimer page covers this in more detail.
Once a page is loaded, most calculators continue to work without an internet connection — they run in your browser. A few specific tools (currency converter, weather lookup, IP lookup) call live APIs and need network access for fresh data.
Yes. The whole site is built phone-first. Inputs are touch-friendly, results are readable on small screens, and the navigation collapses to a single hamburger menu on mobile.
Open the Contact page and send a message. The editorial inbox is read by a human within 24 hours on weekdays. Bug reports are confirmed and fixed within 48 hours; tool requests get a brief reply and jump into the build queue if they are useful to a broad audience.
From peer-reviewed publications and the official guidance of professional bodies — the same sources clinicians, dietitians and financial planners use. The Methodology page explains the editorial process and the Editorial team page covers who writes for the site.
Dailiyo started with a simple frustration — every small task ended in five tabs of ads, popups and sign-up walls. So we put the most useful calculators, converters and short guides under one clean roof.
Whether you are checking BMI before a check-up, converting an image for a job application or counting words for a school report, the goal is the same: get in, get the answer, get on with your day.
