### 4/5 — 内容はいいのにアクセス不具合とフリーズが多発

*2026-02-22*

長女のときからずっと利用しており、もう9年近く使わせてもらっています。
中学受験でも娘がシンクシンクをやっていてよかったというほど、特に図形問題にプレミールが役立ちました。
しかしながら、とにかくアプリのフリーズやアクセス不具合が多く、1プレイごとに立ち上げ直してやることがストレスです。
タブレットをある程度新しいものに買い替えても改善しません。
そこまで重たいシステムではないように感じますが9年間改善ないように感じます。

小さい子どもでは大人がアプリを立ち上げ直す必要があるため1人ではできずません。

コンテンツはこれ以上アップデーと望まないので普通にプレイできるアプリであってほしいです。

**Developer response:** シンクシンクをご利用いただきありがとうございます。このたびは、長年継続いただいていたにも関わらず、ご不便をおかけし誠に申し訳ございません。お手数をおかけいたしますが、cs@think.wonderfy.incまでお問い合わせいただけますと幸いでございます。何卒、よろしくお願いいたします。

### 5/5 — extremely helpful app

*2026-01-11*

This app has a variety of puzzles and games to teach critical thinking to kids. loved the app and the concept of one puzzle a day in free version so that children remain bounded by discipline

**Developer response:** Thank you very much for using Think!Think!
We are delighted and encouraged to receive your positive feedback.
Our team will keep striving to provide you with exciting and stimulating content.
We very much hope that you continue to enjoy Think!Think!

### 5/5 — 재미있당

*2025-03-12*

현질해야만 좋은기능있는거 빼고 다 좋아요 그래도 재미있어요 ^^

### 4/5 — 引き継ぎあたりがすごく手間。

*2024-10-12*

中身は値段高いぐらいが不満かな。そんなことより子供用なんで、家では自分のパッドでやってても、ちょっとのお出かけ時には持って行ってないことがあるので、アカウントの違う複数のタブレットでできて欲しいのだけど、仕様が変わってて、今やりたいのよ！って時にできなくてイラッとしたわ。5分大人しくして！な感じだったから、前のパス発行のが機種変後とか楽やったのに。
多分、確認メールを、アプリ起動したいデバイスで開かないといけない仕様だったんかな？他ので開いたからダメだったとかのトライ時間がかかったのよね。メールのパワードを調べて、やだなーと思いながら子供のタブレットでメール開き手間だしまたタブレット増やしたらこの手間かかるんか( ㅎ ㅎ)……。
できる回数は一緒なんだから子供がするゲームはすんなり別ディバイス、アカウントでも共有できるようしといてほしい。共有せん方が無料分あるから多いぐらいよね。

**Developer response:** このたびはアカウント引継ぎにおいてご不便をおかけしてしまい申し訳ございません。現在は、アプリ内でご登録いただいたメールアドレスを利用することで「他端末へのアカウント共有」「アンインストールなどで消えてしまったアカウントの復元」が行える仕様となっておりますが、以前よりも引継ぎ時の手順が増えたことで混乱をお招きしてしまう場面もあるかと思います。よりスムーズにサービスをご活用いただけますよう改善を重ねて参りますので、今後ともシンクシンクをどうぞよろしくお願いいたします。

### 1/5 — Frustrating

*2024-08-09*

My child wants to play and yet is limited to 3 games a day? Why am I paying a premium subscription for a game he care barely play? Unsubscribing.

**Developer response:** Thank you for using Think!Think!Think!Think! has set play limits out of consideration for the wellbeing of young learners and to ensure that they can continue to use the app consistently over time. It is not possible to completely remove these restrictions, even using the paid version of the app.We are sorry that we are unable to fulfil your request.We hope you continue to enjoy using Think!Think!

### 4/5 — 起動しなくなりました

*2024-07-30*

起動しなくなりました。他の方が言うように、アプリのアップデートからでしょうか？それともこちらの古いiPadに対応できない？iOS12.5.7

前回のアップデートも同じで、その後対応でまた遊べるようになりましたが…

**Developer response:** いつもご利用いただきありがとうございます。このたびは混乱をお招きしてしまい申し訳ございません。アプリの保護者メニューにてお知らせいたしました通り、対応バージョンの引き上げに伴い、2024年3月31日をもってiOS 14.0未満の端末はサポート対象外となってしまっております。恐れ入りますが、対象端末にアカウントをお引き継ぎの上、引き続きお楽しみいただけましたら幸いです。引継ぎが上手くいかない場合は、お手数をおかけいたしますが、cs@think.wonderfy.incまでお問い合わせくださいませ。これからもシンクシンクをどうぞよろしくお願いいたします。

### 5/5 — とても良いのですが質問があります

*2024-07-27*

シンクシンク始めてから７か月｡⭐️が500個集まってその翌日、レジェンダリオン(？)という謎の惑星が遊べるようになりました｡ [質問] ❶レジェンダリオンとバベロンはなぜ最初のプレイヤーは遊ぶことができないのですか?(毎週月曜日カートめくり) ❷なぜレジェンダリオンはシンクトピアやプレミールみたいでわなく週に1種類なのですか? ❸なぜバベロンとオリンピコ以外の惑星は１日に1種類1プレーなのですか ❹オリンピコ大会はなぜ1ヵ月に1回なのですか？またワールドカップはなぜ3ヶ月に1回なのですか？ ❺なぜシンクトピアやプレミールでは右下の箱から1日に1回しか問題の種類が追加できないのですか? ❻1番最後のロケットの先は何があるんでしょうか？ [追加して欲しい機能] ❶1 プレーで最大3個ではなくて、もっと稼げるようになったらいいです｡ ❷バベロンの塔や城の問題50問研ぎ終わったら星を一気にもらうとか、そういう報酬があるといいです❸ひらがなカタカナモードではなくシンクシンクの全てが漢字混じりで遊べると設定だといいです｡

**Developer response:** いつもご利用いただきありがとうございます。シンクシンクの魅力をたくさんお話いただけてとっても嬉しいです。惑星オリンピコで行われる大会は月に１度１週間のみと期間限定となってしまいますが、月例大会は毎日挑戦いただけます。ぜひたくさん遊びに来てくださいね。

### 1/5 — UPDATES!

*2024-07-22, version 4.8.2*

TO MUCH UPDATES AND THE MINI GAMES TOOOO BORING!

### 1/5 — Waste

*2022-06-30*

I was like I need a new game then I saw this game so I tried it out 3 times per day. I thought this was fun, but 3 times? Forget it I’m not gonna spend 3 times which are like only 2 mins so I deleted it.

**Developer response:** Thank you for your review. We have set a limit on the number of times our users can play out of consideration for our users (mainly children's) health. If you choose to sign up to the paid course, you can choose between two types: a) either three times per day or b) 21 times per week depending on whichever pattern best matches your lifestyle.

### 5/5 — 五つ星以外はあり得ない

*2022-03-05*

高レベルのゲーム、頻繁にアップデートされて、さすがです‼️
毎月会費を払っても全然お得です。我が家では2人重宝しています。

**Developer response:** いつもご利用いただき誠にありがとうございます。そのようなお声をいただけますと大変励みになります！お気づきの点がございましたら、ぜひご意見お聞かせくださいませ。これからもご期待にお応えできますよう、スタッフ一同、尽力してまいります。
