Yes — it is built for exactly that person.
The 28-day challenge starts from the beginning: what a share actually is, what a price means, why it moves. It does not assume you know what a spread, a candle, or a market order is. Each lesson is a few minutes and unlocks in order, so there is no way to end up somewhere you are not ready for.
The simulator matters most for beginners, because it lets you make the expensive mistakes cheaply. Buying too much of one thing, panic-selling a dip, holding a loser too long — these are much better learned with demo coins than with rent money.
One honest caveat: finishing Finoha will not make you a profitable trader. Simulated results and real results are different things, and we say so throughout the app. What it will do is make sure you understand what you are looking at.
