### 1/5 — 広告が多すぎる

*2026-07-05*

何度も閉じるボタンを押す必要のある広告が多すぎて毎日やるなんて正気じゃない。

### 3/5 — いい

*2026-06-28*

だがしかし広告を消したい

### 2/5 — 広告減らせ

*2025-02-11*

広告が多すぎる2回に１回広告来るから楽しくても広告のせいでイライラする

### 1/5 — 広告うざい

*2025-01-26*

始める時に出てきて広告が終わったあと「ボタンを押してください」って出て押したら1687ミリとか意味わからん広告中も続いてんのかよ

### 4/5 — ボタンが見えずらい

*2024-12-28, version 3.2*

楽しいけどボタンが見えずらかった

### 2/5 — 凄く難しいが、シンプルで成長度がよく解る

*2024-12-24*

普段のんべんと暮らしているので、どれだけ劣っているかがよく解る。逆に、集中してる時に自分が、彼と同じ状態になってるのもよく解って、集中するとこんな風にやっぱなるんだ、と笑って仕舞った（じゅじゅの彼です（笑）
唯ね広告が煩わし過ぎてどうしようもないので、WiFi切ってやってます。開発者殿、此じゃ元も子もないでしょ、もう少し頻度を下げて下さんせ、ひまつぶ系も結構頻度高いんですが其でも此のアプリよりは悪質じゃない

### 3/5 — ほんとに測れてる？

*2024-10-23*

同じ値ばっかり出るんですが、ネットで検索してたやつではもっと早く記録されました。
まぁお遊び、子供向けですね。
真剣に図りたい人はインターネットで検索して1番上に出てくるやつオススメします。

### 5/5 — おもろい

*2024-10-13*

地道に上がっていく楽しさがあり成長が数字に見えてやりがいがある
けど広告多いのは問題点かもしれない
広告気にならない人はオススメ！暇つぶしにもいいよ〜

### 3/5 — 勘ゲーム

*2024-09-30*

何度でもすぐにやり直せるので勘で押すだけのゲームです。スコア自慢は全員コレ

### 5/5 — おれ

*2024-08-21*

最高に楽しい
きもぢぃ
