What helps me help you
- What you expected and what happened instead.
- The question, if it is about a question — its wording is enough to find it.
- Your device and iOS version.
A question looks wrong
Tell me which one. Questions are generated from catalogs, so a wrong question is usually a wrong rule rather than a typo — and fixing the rule fixes every question like it. That is worth more than one correction, so these reports are the most useful ones I get.
Why there is no reading or listening section
Because I have no material for either, and a section built from nothing would measure nothing. The app says this on its opening screen, before you start, rather than in the small print afterwards.
Why the test does not tell you if an answer was right
Because seeing three mistakes in a row changes how you answer the fourth. The result would then describe your nerve rather than your Japanese. The result comes at the end.
The debrief did not arrive, or says something odd
The debrief is written by a language model and it can be wrong. Where it contradicts the numbers on screen, the numbers are right: your level and your share of mistakes are worked out by the app on your phone, with no outside help. Write and tell me what it said and at what result — that is a report I can act on.
If it did not arrive at all: a sheet too thin to produce a result gets no debrief — if too much ran out on the clock, there is nothing to discuss. Beyond that, the feature needs a network connection; it is the only part of the app that does.
