Complete JLPT exam prep app with full mock tests
Problem
Learners preparing for the JLPT (Japanese Language Proficiency Test) can't find a single app covering all exam sections with realistic mock tests - they juggle multiple partial apps and still lack timed, full-exam simulation before test day.
Opportunity
A focused JLPT prep app with section-by-section practice, timed full mock exams matching the real test format, and progress analytics per section - a clear, underserved niche within language learning.
Market analysis
The premise is weaker than it sounds: Migii JLPT already offers structured, timed mock exams across all sections and levels and is widely recommended, while free sites like NihonEz, Uno Japano and JapaneseQuizzes cover full-format practice at zero cost. The telling signal is that the poster did not find Migii, which points at a discovery and SEO gap rather than a product gap.
Market · Global self-learners preparing for JLPT levels N5-N1; motivated, exam-deadline-driven audience that recurs every test cycle.
Pricing · Proven willingness to pay in the niche: Migii runs paid subscriptions and gets recommended as worth paying for; free alternatives anchor expectations low, so pricing sits in typical language-app territory (roughly $5-15/month).
Pros
- + Exam-date urgency creates natural spikes of intent and conversion twice a year.
- + Willingness to pay is proven by existing paid JLPT subscriptions.
- + A single-level-deep product (N5 done perfectly) could win the entry funnel and expand up.
Cons
- − Migii JLPT already delivers the exact proposal: full timed mocks across all sections.
- − Free mock-test sites (NihonEz, Uno Japano, JapaneseQuizzes) satisfy the core need at zero cost.
- − Producing authentic-format question content for five levels is expensive and never finished.

The most interesting data point in this thread is the question itself: a motivated learner with a deadline searched for an all-in-one mock-test app and failed to find Migii, the product that already exists. That is a distribution opening, not a product opening. A newcomer should compete where Migii is weakest, which is depth per level and test-day realism (strict section timing, real interface pacing, weak-section diagnostics), and dominate the “JLPT N5 mock test” search and app-store queries that evidently still surface nothing definitive. Content is the moat here, and it must be budgeted as a permanent cost, not a launch task.
