## What is G?

Pass Japan's JDLA G-Test (Deep Learning for GENERAL) — the dedicated study app for Japan's leading AI/Deep Learning literacy certification.

Aligned with the latest JDLA syllabus, every one of the 500 multiple-choice questions comes with a clear explanation so you understand the *why*, not just the answer. Build practical knowledge in artificial intelligence, machine learning, deep learning techniques, AI ethics, law, and statistics — all in your pocket.


◆ THREE STUDY MODES

[Practice]
Solve questions across every syllabus topic, with detailed explanations after each answer. Strengthen your foundations on AI overview, machine learning methods, deep learning components and applications, AI ethics, law & contracts, and mathematical statistics.

[Smart Review]
Choose between weak-spot, forgetting-curve, or random algorithms. Spaced repetition keeps everything you learned in long-term memory and turns mistakes into mastery.

[Mock Exam]
Sit a full exam-format simulation and see exactly where you stand against the pass line. Realistic timing, realistic difficulty.


◆ SUPPORT TOOLS

• Glossary — tap any term in a question or explanation to see its definition instantly. Covers neural networks, gradient descent, transformer, prompt engineering, and more.
• Notes & Bookmarks — capture your own insights and revisit tricky questions.
• Full-text search — find any question in seconds.


◆ TRACK YOUR PROGRESS

• Today's stats: study time, accuracy, and progress at a glance.
• Daily / weekly / monthly charts for time and accuracy.
• Topic-by-topic accuracy to surface weak spots automatically.
• Goals to keep your study pace on track.


◆ OFFLINE, AD-FREE & PRIVATE

All questions, explanations, and the glossary are stored on your device. Study on the train, on a flight, or anywhere with no signal. Zero ads, zero distractions — and your data never leaves the app.


◆ WHO IT'S FOR

### 5/5 — 合格しました！

*2026-07-02*

このアプリのみの学習でG検定合格できました！特に何も考えずにスキマ時間で進捗進めるように学習しただけです。まさかそれだけで合格できると思わなかったので自分でも驚いてますが、間違えだ問題だけを繰り返し復習したりしたこと、解説が丁寧なのとAIに質問したりして暗記ではなく理解して学習を進めたのが良かったのだと思います。5月頃は不具合がちょこちょこありましたが今はだいぶ解消されてるようです。

**Developer response:** 合格おめでとうございます！本アプリをご活用された上での合格とのことで開発者としてとても嬉しく思います！リリース当初は不具合でご不便おかけしまして大変申し訳ありませんでした。現状解消されている不具合がほとんどかと存じますが、もし気になる点や機能の改善要望などありましたら気兼ねなくご連絡いただけますと幸いです（合格されたとのことですので、もう本アプリを使うことも少なくなるかとは思いますが）引き続きよろしくお願いいたします。

### 5/5 — アップデートでどんどん使いやすくなる

*2026-07-01*

頻繁にアップデートがある印象ですが、毎回アップデートのたびに使いやすくなります。初期は多少の不具合が散見されましたがだいぶ改善されてます。直近ではAIへの質問機能と進捗に合わせた自動学習がかなり便利で嬉しいです。これからもアップデート楽しみにしてます

**Developer response:** 貴重なレビューいただきありがとうございます！ご要望や機能改善には積極的に取り組んでますので、引き続きご評価よろしくお願いいたします！

### 1/5 — 学習履歴が消えた

*2026-06-26*

アップデートによってこれまでの学習履歴が全て消えました。もうすぐ試験なので、これまで間違えた問題だけやり直したかったのに。
ものすごく残念です。

### 1/5 — ないかな、、

*2026-06-11*

スクショにある使いやすさ第一位って何情報ですか？
問題の品質も残念な状態です。

**Developer response:** 貴重なご意見いただきありがとうございます！大変お手数ですが問題のどの辺りに品質の低さを感じたのかをご連絡いただけますと幸いでございます。より良いアプリにするため改善に努めさせていただきますので、でもしよろしければ「設定 > 問い合わせ」よりご意見をいただけますでしょうか。よろしくお願いいたします。

### 5/5 — 解説がわかりやすく単語辞書が超便利

*2026-05-20*

3000円でAmazonで買った参考書やりも解説がはるかに丁寧でわかりやすいです。あと単語辞書が本当に便利で単語の解説の中でわからない単語をリンクして続けてみれるので、単語を辿ってくだけでもかなり勉強になり知識が定着します。より詳しく調べたいときにワンタップでGoogleで検索できるのも地味に便利でした

**Developer response:** 貴重なレビューいただきありがとうございます！ご要望や機能改善には積極的に取り組んでますので、引き続きご評価よろしくお願いいたします！
