Everything You Should Know About AfriWidget
AfriWidget started with a simple idea: the everyday tools that people in richer countries take for granted — a quick way to check your BMI, work out a loan payment, or see how your savings might grow — should be just as easy to use for someone in Accra, Lagos, Nairobi, or Johannesburg. Not locked in an app. Not hidden behind a sign-up form. Just a webpage that opens, works, and gives you an answer.
The site has grown since then. Today there are more than 120 tools across four main areas: Education, Finance, Health, and Productivity. Every one of them is free. Every one of them runs inside your own browser. And every one of them is written and maintained with a single guiding rule: if it does not help someone, it does not belong on the site.
How our tools are built
Each AfriWidget tool is a self-contained webpage. When you open it, your browser downloads a small file that contains the logic of the calculation. From that point on, everything runs on your device. The maths happens in your browser, using your own processor. The result appears on your screen. No round trip to a server.
We use plain, everyday web technology for the tools themselves. We deliberately avoid heavy frameworks and complicated build systems, because those things make pages slower to load and easier to break. A simple page loads quickly on a slow connection and works on a five-year-old phone. That matters enormously when you consider that many of our users are on mobile data plans and mid-range devices.
How we check every formula
Before any tool goes live, we verify its formula against at least two trusted sources. For health tools, those sources are typically the World Health Organization, national health services, or published medical research. For finance tools, they are the standard mathematics that banks and regulators use. For education tools, they are the official rules published by each country's exam body or university system.
We then test the tool against worked examples from those sources. If the official example shows a specific answer, our tool must produce the same answer. Only then does the tool go live. Where there is no official worked example — because no authority publishes one — we cross-check with established calculators from reputable institutions and note the source on the page.
Privacy that is built in, not just promised
Many websites say they respect your privacy in a policy document that most people never read. We wanted to do something stronger. At AfriWidget, your privacy does not depend on us keeping a promise — it comes from the way the site is built.
Because every calculation happens inside your browser, there is no mechanism by which your inputs could be collected, even if we wanted to. There is no database of calculations. There is no log of what you typed. The strongest possible privacy is not needing to trust anyone in the first place, and that is what we have aimed for.
You can test this claim for yourself. Open the developer tools built into your browser, watch the network activity while you use a tool, and see for yourself that no message carrying your numbers leaves your device. We would rather you check than take our word for it.
How the site stays free
AfriWidget is supported entirely by display advertising through Google AdSense. There is no premium plan, no subscription button, and no plan to add either. A small amount of revenue from ads covers the cost of the servers, the domain name, and the many hours that go into building and maintaining the tools.
We deliberately keep the ads out of the way. They appear in fixed positions on the page, never between you and your result, never popping up as you type, and never disguised as part of the tool itself. If you see an ad that looks misleading or out of place, you can report it directly to Google using the small icon on the ad, and we would also appreciate a note through our contact page.
Designed for everyone
We work hard to make every tool usable by as many people as possible. The colour choices meet accessibility contrast standards. Interactive elements can be reached with a keyboard. Form fields are labelled so screen readers can announce them correctly. Where a page does not meet those standards, we treat it as a bug and fix it.
Language is the next frontier for us. AfriWidget is currently written in English, but tens of millions of our potential users are more comfortable in French, Swahili, Hausa, Yoruba, Igbo, or Amharic. Translating the site is on our roadmap. If you are a fluent speaker of any of these languages and would like to help, we would love to hear from you.
What AfriWidget is not
It is worth being clear about the edges of what we offer. AfriWidget is a tool for learning and planning. It is not a doctor. It is not a financial advisor. It is not a lawyer. It is not a substitute for any of those professionals, and it does not pretend to be.
Our mortgage calculator tells you what a monthly payment would look like at a given interest rate. It does not know your lender's specific fees, insurance requirements, or the rules that apply where you live. Our BMI tool gives you the same number a clinic would calculate, but it cannot examine you or know your history. Use our results as a starting point, and take them to a professional for the conversation that matters.
Getting in touch
A real person reads every message sent through the contact form. There is no automated bot filtering your words, and no ticket number that disappears into a queue. If you report a bug, we will investigate. If you suggest a tool, we will consider it carefully. If you just want to say hello, that is fine too.
AfriWidget is being built for the people who use it. Every tool that exists today exists because someone said it would help. Every tool that comes next will come the same way. If you have an idea, a correction, or a question, please do not hesitate to reach out.
