Study apps for the exams that qualify people to work
BiDaFa Ltd builds practice and revision apps for occupational licensing and certification exams: the tests people sit before they can work as a notary, a security guard, a tradesperson or a licensed operator.
Our first apps are in development and are not yet available to download.
What we do
Occupational licensing exams decide whether someone is allowed to do their job. They are set from published statutes, regulations and official training manuals, they are often sat once or twice a year, and failing one can cost a person a season of work.
The study material for them is frequently poor. BiDaFa Ltd exists to build the practice apps those candidates actually need: accurate, specific to one jurisdiction and one exam, and derived from the official source rather than from a general purpose question bank.
How we build
These are the principles our apps are designed to, not claims about products in the store. Nothing of ours has launched yet.
-
Built from the official source material
Questions are written from the published rules, statutes and training manuals the exam itself is set from, with the source recorded, rather than from guesswork about what might come up.
-
Every answer explained
A wrong answer only teaches you something if you learn why it was wrong, so each question carries an explanation rather than a bare score at the end.
-
Yours once you buy it
Apps are designed to work offline and to be a single purchase, with no subscription, so revising does not depend on having a signal in the exam centre car park.
About the company
BiDaFa Ltd was incorporated in England on 8 August 2026 and is registered as a business and domestic software development company, number 17388837.
It is a small independent company. The research, the writing and the building are done in house, which is the reason we can be specific about a single jurisdiction rather than general about many.
