## What is Kraepelin Training?

The Kraepelin test is:
Add adjacent numbers, and answer the last digit.
For example, if the numbers in a row are 3 and 9, 3+9=12, the correct answer is 2.
Kraepelin consists of 15 minuites in the first half, 5 minuites rest, and 15 minuits in the second half.
We recommend 15 sets of 60s for practical training with our App.

### 3/5 — 手書き入力の精度

*2026-05-17*

有料版の手書き入力の精度がイマイチ
別な数字を認識され誤回答と表示されると集中力が削がれる．．．
そして誤回答時の赤字表示をOFFにしても設定が変更されず、正答しても間違えの表示が出てきてイライラ
集中力が必要なテストで集中力を削がれるとちょっとな😅

### 1/5 — 手書き認識の精度が低い

*2025-11-26*

手書き機能は削除した方が良いレベルです。正確に識字されません。

### 2/5 — 手書き入力機能が有料なら先に書いてほしい

*2025-02-06*

「手書き入力使えるの！？いいなぁ」と思ったら後から「有料版で」とか言われて不満です

### 2/5 — 有料はやめた方が…

*2024-11-30*

無料のタッチはいいが手書きの数字は全然正確に読み取ってくれない。

### 3/5 — 有料版　文字の誤認識が多い

*2024-02-08*

よくできたアプリだとおもったのでー、有料を購入したが数字の誤認識が多い。9と書いたのに1とか4になる。ストレス

### 3/5 — 色々と惜しい

*2023-10-20*

5や3と書いたのに9として認識されるなど、手書き入力の識別精度が悪いなと感じる。
また、認識速度も速いに設定すると回答を書き終わる前に認識して次へ行ってしまう位極端な速さになってしまう。
他の箇所は良い所ばかりなだけに色々と惜しいなと感じた。

### 2/5 — 広告でまともにできない

*2023-04-24*

画面下の広告が大きく、0のボタンが入力できません。アプリの出来は良い分残念です。

### 3/5 — 良いですが。。。

*2022-11-18*

手書き入力が可能かなので有料版を購入しました。
手書きの反応速度について、三段階の調節が可能ですが、普通や低速では反応速度が遅く感じますし、高速は逆に速すぎて、記入の途中の状態で数字を認識してしまい誤回答となることが多々あります。

結局、数字をタップするパターン（無料版）を使ってました。
無料版については、数字の大きさが小さくて押し間違いがよくあり、もっと数字を大きくしてもらえればと思いました。

よって⭐︎3です。

### 5/5 — 助かりました

*2022-09-18*

適性検査(V-CAT)対策に使用しました。手書きの7を9に誤読されることが多いですが、意図して横幅を広く書くと7と読んでくれます。お陰様で第一志望の検査を通過して内定が取れました。ありがとうございました！

### 5/5 — 有料版の手書きモード

*2022-07-23*

しっかりと書いた数字を読まない。
有料版は練習にならない。
