A $2.99 quiz app caught 8,000+ Ukrainian law master's graduates' final exam

A practicing lawyer in Lviv launched a quiz app two months before the exam. The question bank is for the ЄДКІ that Ukrainian law master's students must pass to graduate, and it sells for only $2.99. Comparable web courses cost $100 to $200+. The closer the exam gets, the higher it ranks in Ukraine's education Top Grossing chart. The market is small and very seasonal, but the playbook can be reused with another exam or another country.

"Too bad we didn't have you before"

On Oct 11, 2026, a Ukrainian student gave LawPrep 5 stars on the App Store. The title: "Good, but it can't go full screen on iPad." The body was just two sentences: "Thanks, it's convenient, and the questions are exactly what I need. Too bad you didn't exist before."

A month earlier, in Sep 17, another review said: "I'm preparing for the ЄДКІ з права, and this is the first, and probably the only, app that truly has everything."

These two reviews explain the product: something that should have existed long ago only got built in September 2026. The developer is Yuliia Khodachok, and this is the only app on the account. On Instagram she is @yulia_hodachok. She lives in Lviv, lists her job as "Юрисконсульт" (corporate legal counsel), and has 743 followers. The app launched in Sep 9, exactly two months before the Nov 12 exam.

Why this exam causes so much anxiety

The ЄДКІ з права is the unified qualifying exam for master's graduates in the "Law" and "International Law" programs in Ukraine. You need to pass it to receive your degree. It has 120 questions in 180 minutes, built around case studies, with single-choice, 7-choose-3, ordering and matching formats. In 2026, the main session was Nov 12 and the retake was Dec 10. If you fail the retake, you're expelled and must re-enroll and retake it a year later (magistratura.in.ua).

Not many people take it each year. The first session in 2024 had 8,000 people from 119 universities (osvita.ua). In 2025, 8,600 people took it (Ukrainian Wikipedia), and 19.2% of them failed (Pravozno website). The passing score is only published after the exam. In 2024 it was 38 out of 115 points, so before the exam nobody knows what score is safe.

Few people, mandatory, a heavy cost of failing, and only one main session: that is the market.

What it is

An iPhone quiz app in Ukrainian. What the website and store page list:

• 3,000+ questions, organized by 13 subjects and topics. You can keep going question after question, and the correct answer and explanation appear right after each one.
• Full mock exam: 120 questions in 180 minutes, with an untimed study mode and a timed "real" mode.
• A wrong-answer notebook and per-subject stats. Missed questions come back on a spaced-repetition schedule.
• Glossary cards, offline use, push reminders.

There is one in-app purchase: "LawPrep Premium, $2.99". The store page doesn't say whether it's a one-time purchase or a subscription. The Android version came later. On Play it's published under another name, Dmytro Skochko, with 100+ downloads and 12 reviews (Google Play, 11-06). This suggests a technical partner. iOS is the main platform.

In two months it shipped 9 versions: Sep 13 added two mock-exam modes, Sep 21 added offline use, Oct 2 added push notifications and answer history, Oct 10 added glossary cards, and Oct 17 added spaced repetition for wrong answers. The update notes repeatedly say "thanks for your feedback".

Why now

Exam timing. Its position on Ukraine's education Top Grossing chart was #28 on Oct 68, #30 on Oct 39, and #6 on Nov 28. On the Top Free chart the same day it was #53. The closer it got to Nov 12, the higher it ranked, the classic pre-exam sprint curve.

Price. Nearly all comparable products are web courses. Connected charges 3,683–4,520 hryvnias (about $90–110) for its question bank alone. Pravozno's group course costs 3,950 and 10,000 hryvnias, and magistratura.in.ua's intensive course costs 9,600 hryvnias. For a student, $2.99 is an easy decision.

The search spot is empty. The app's name literally includes "ЄДКІ з права". Searching "ЄДКІ" in the Ukrainian App Store puts it first. Second is a multi-exam platform app with only 1 ratings, and below that are all medical exam quiz apps.

Rating counts follow the exam calendar too: Oct 28 74, Nov 6 96, 9 days, 22 more; iTunes shows 103 ratings in the Ukraine store, averaging 4.96.

Where users come from

Only two things are confirmed: App Store search, and the demand the exam itself creates.

Other channels are barely visible. On TikTok, searches for "lawprep", "ЄДКІ" and "єдкі тести" return no videos from it. On X, nobody has mentioned it in nearly 60 days. No media coverage. The store privacy label lists "third-party advertising: identifiers", so the app integrates an ad attribution tool and may be running Instagram ads, but no ad creatives were found (inferred, not confirmed). The website lawprep.com.ua is a landing page with an FAQ, and it gets Google organic search traffic, though the volume is unknown.

The rest of the inference comes from classmates passing it around: law master's programs have several thousand students a year, each school has its own student groups, the ratings are all 5-star, the reviews read like real students wrote them, and the founder is himself in legal circles.

How much money

Very little. Apple doesn't disclose revenue, and the Ukrainian store has a low bar, so a #28 ranking in education probably means a few hundred to a thousand or two dollars a month. Rough math: one cohort is 8,600 people. Even if 10 to 20% buy Premium, that's a few thousand dollars per session (est.). After the Dec 10 retake, demand falls off a cliff, and the next wave doesn't come until autumn 2027.

This is a small tool built by someone in the field for their own industry, not a business that can support a team.

Who it's competing with

A reference point: for Ukrainian medical students' national exam КРОК, quiz apps like MedKrok (8,300 ratings) and K-Test (3,700 ratings) have existed for a long time. The law side was empty, and LawPrep filled that gap.

No copycats seen so far.

If it were you

Verdict: Going head-on against LawPrep for the law ЄДКІ isn't worth it. It already holds first place in search with a full 5-star rating, and the market is only about 8,000 people a year. The part worth copying is the formula: a national, mandatory exam with high stakes, where the existing prep products are expensive web courses and the language is small. Have someone who knows the field build the question bank into a native quiz app, sell it for $2–5, and put the exam name in the title to take the top search spot.

Who it suits: people who already work in an industry, have questions on hand, and speak the local language, or indie developers who can partner with them. One person can ship a first version in two months.

Who it doesn't suit: anyone hoping to make a living from one app. A single exam runs once a year, and one session brings in a few thousand dollars (est.). To make real money you need to build a whole row of exam apps, like Ukraine's Igor Dyrda, who runs prosecutor and customs exam apps that ranked #24 and #39 on the same day's education Top Grossing chart.

How to do it:

• First, find the next gap in Ukraine. ЄДКІ is spreading into other majors: the Ministry of Education list already includes cybersecurity, public administration, veterinary medicine and more. Search the App Store for each exam name. If the top result has only single-digit ratings, that's your gap.
• Or switch countries: Central/Eastern Europe, Latin America, Southeast Asia. Bar exams, accounting, nursing, civil service tests. Anywhere that searching the exam name only returns web courses is the same opportunity.
• Build the product from the feature list: drill by subject, instant explanations, full timed mock exams, spaced repetition on wrong answers, offline mode. Question accuracy matters more than features, so build the bank from real exam formats.

How to get users: Put the full exam name and year in the app name to win store search. Launch two to three months before the exam to catch prep season. Get into student groups and Telegram channels, and have past test-takers and tutors share it. Build a website with a FAQ to catch Google search.

When to start: Work backward from the exam date. The app needs to be in the store two months before the exam. Miss that and you wait a year.

Signs you're wrong: A month after launch, you still don't rank top three for the exam name, or paid conversion is well below ten percent of a single cohort. Either the test-takers aren't prepping on their phones or someone already owns the spot. If the question bank gets flagged for wrong answers and the rating falls below 4.5, the moat is content, not the app.
