## What is Flips?

Flips is a flashcard app that brings back each card right before you're about to forget it. Built on the forgetting curve and spaced repetition (SRS), it works for anything worth memorizing — vocabulary, exam terms, dates, professional jargon, and more.

Key Features
・Just-in-time review (SRS)
Cards resurface automatically at the best moment to review. Mastered cards space out; shaky ones come back sooner — the shortest path to remembering.

・Simple, fast study sessions
Open the app and start right away. Swipe or pick from 4 choices — nothing gets in the way of focus.

・Memory home screen
A chart shows what you've learned, what's fading, and what's new at a glance. Today's study count is always clear.

・Streaks to build the habit
Your study streak is shown like a calendar, so daily effort visibly adds up.

・Forgetting gauge & levels
See each card's "risk level" in your deck list, so you always know what to review first.

・Create decks & import
Build a deck in minutes, or import from CSV/TSV.

・Notifications at the right time
Get reminded exactly when review will be most effective.

・Text-to-speech (TTS)
Hear pronunciation for listening practice or a quick check. (Supported languages depend on your device; more are added over time.)

Great for
・Language vocabulary: words, phrases, listening practice — Spanish, French, Japanese, or any language
・School & exams: history dates, science terms, formulas, standardized test prep
・Certifications: professional exams, medical, legal, and IT terminology
・Anything else: whatever you need to memorize

How it works (3 steps)

1. Pick a deck or make one (ready-made vocabulary decks, or build your own)
2. Start studying (cards you're about to forget come up first)
3. A little every day (streaks and charts make progress visible)

Why you'll remember with Flips
・Science-based: spaced repetition tuned to the forgetting curve optimizes your review timing
・Built for focus: a stripped-down interface, studying in two taps
・Priorities made visible: the forgetting gauge and "due today" count remove the guesswork
・Built for habit: streaks keep you coming back

Common ways people use Flips
・Students: vocabulary, historical dates, formulas, test prep
・Working professionals: certification vocabulary, technical terms, on-the-job knowledge
・Language learners: vocabulary across any language you're studying

What Flips values
・Simple and fast: built to help you focus purely on remembering
・Visible progress: progress, streaks, and forgetting risk, always in view
・Flexibility: build your own decks or import to fit any subject

Start for free, and build a study habit around reviewing right before you forget.

### 4/5 — もっとこういうのがあれば...！

*2026-08-24*

すごく良いアプリだと思います！
ただ、単語帳の中身の編集機能で、選択消去であったり、別の単語帳に移動させる（コピー含む）ような機能があれば本当に最高だと思いました！

### 5/5 — めっちゃいい

*2026-07-02*

すごく使いやすいです。
やらなきゃ行けないタイミングが分かるのがとてもいいと思います。
1つお願いなんですが、学習範囲の指定を毎回入れなくてもいいように前回のまま保存されるようにして欲しいです。

**Developer response:** あたたかいお言葉、ありがとうございます。とても励みになります。学習範囲を毎回入れなくていいように、というご意見も参考にさせていただきます。これからも使うたびに「ちょうどいい」と思ってもらえるアプリを目指してまいります。今後ともFlipsをよろしくお願いいたします。

### 5/5 — こういうアプリを探してた

*2026-06-12*

参考書や模試の問題でわからなかった単語をまとめるのに使っています。とても便利なアプリをありがとうございます😭
ただ、カードをめくる時にタップだけでなく長押しでも、触れた瞬間にカードが捲られるようにして欲しいです。そうすれば押して答えを確認し、そのままスワイプできて効率的だと思います。よろしくお願いします🙇

**Developer response:** あたたかいコメントをありがとうございます、励みになります。長押しでもめくれるように、というご提案も参考にさせていただきます。単語帳が学習の助けになっているようで嬉しいです。これからも便利に使っていただけるよう、引き続きがんばります。

### 3/5 — ここだけなとかして欲しい、！

*2026-05-25*

習得とかに入ったはずなのに時間が経つと未学習になるのは何故ですか？少なくとも学習はしてるのに

**Developer response:** ご意見ありがとうございます。少し補足させてください。Flipsは忘却曲線をもとに、時間が経って忘れやすくなったカードを自動で「未学習」に戻し、もう一度復習をうながす仕組みになっています。せっかく覚えた単語を忘れないようにするための動きですので、ご了承いただけますと幸いです。

なお、同じ単語で正解を重ねていくと、「未学習」に戻るまでの期間はどんどん長くなっていきます。覚えたての単語ほど早めに復習をうながし、しっかり定着した単語は間隔を空けていく、という仕組みになっています。わかりにくい部分があれば教えてください。

### 1/5 — もしかしてコピペができない

*2026-02-23*

単語帳を作るときにはコピペができませんでした。これは仕様？

**Developer response:** アプリをご利用いただきありがとうございます！

単語帳の作成でコピペができなかった件ですが、確認したところ不具合が発生しておりました。ご不便をおかけしてしまい、本当に申し訳ありません。

すでに修正版をアップデート済みですので、最新バージョンでお試しいただければと思います。

大切な不具合に気づかせていただき、心より感謝申し上げます。
引き続き、どうぞよろしくお願いいたします。
