Otherwise I'm very happy ### 2/5 — Awkward to find the things you want to put on canvas *2025-06-12, version 3.4.6* Could not find basic shapes, the over UI experience was difficult for me ### 3/5 — 有料版へのアップグレードができない。 *2024-07-10, version 6.4.7* とても素晴らしいアプリだと思います。 仕事上での使用はもちろん 資格勉強のためにマインドマップ作成にも役に立つなと思いキャンバスやカードを増やすためにアップグレードしたいが案内とプライバシーポリシーや利用規約が表示されるだけでアップグレードの仕方がわからない。 ### 2/5 — Confused, but holding hope. *2024-04-17* ThinkSpace is simply non-responsive after installation. I've checked that my system meets requirements. As it does, I'm lost to find a reason. I really want to try this out. I am fully prepared to think it's great... but it needs to function! I've written directly to the developer with system details. I hope I'll get a response that gets me going. I have 5-star hopes judging by feature descriptions and screen shots. ### 2/5 — Обман пользователей и регулярные глюки *2024-03-15, version 6.4.7* 1) при создании 4 холста выскакивает сообщение, что разрешено только 10 холстов в бесплатной версии!! Карл, 10, а не 4 2) не существует создание вашей учетной записи! Просто нет поля зарегистрироваться или создать! А если и как-то автоматически это происходит при установке, то вы не сможете войти учетку! Выдает постоянно «ОШИБКА ВХОДА. СЕТЕВОЕ СОЕДИНЕНИЕ ПОТЕРЯНО» 3) стабильны только клюки в этой программе)))то холст уменьшил и больше не приближается, то карточки залипают, то еще что-то приключится (всех глюков не упомнишь, но они стабильны рпи каждой работе) К) про отсутствие перевода меню, просто молчу. Видимо заменили это видео о том, как функции работают. ### 2/5 — Something has broken it *2024-03-04, version 6.4.7* Used to love this app, until recently. Now when I am on a text card and add a new one to the right or left using the arrows it automatically moves all cards connected to the original card, removing any vertical spsce i had between them. No way to prevent this happening and it ruins layouts. Extremely frustrating as ive been a long time subscriber and makes it pretty much unusable unless its fixed. ### 2/5 — 現状、お金を払えるクオリティではない *2024-01-17, version 3.4.5* アイディアノートとしての機能はかなり優れていますが、バグが発生する頻度が高すぎてその都度再起動が必要になります。 機能確認のために数分触った程度で複数のバグが発生しているので、このクオリティで年間4,000円は高い...。 ただ、備えている機能は本当に理想的なのでバグさえなければ全然お金を払えるアプリです。 ●iMacで使用して以下のバグを確認しています ※いずれもアプリの再起動で解消 ・ズームツールのタブが表示されない ・追加したテキストボックスを再編集できない ### 4/5 — 手写思维导图模板 *2023-12-03* 能出一些手写思维导图模板吗？跟上面软件介绍那样的模板，软件里面的模板不太符合学生使用，如果有的话可以出个教程吗？谢谢🙏 ### 1/5 — 消しゴムを使用すると落ちます *2023-11-30, version 6.4.3* 使用環境　iPadPro 12.9inch 第六世代 ### 1/5 — no no no *2023-11-22, version 6.4.2* awfully uncomfortable. takes so much much effort to create at least a couple of decent maps… ### 3/5 — It’s good, but… *2023-11-06, version 6.4.1* .. not £30.00 a year good. I feel like the developers missing out here. Sell it for £30.00 one time payment, keep functions forever. Then, each year, if you want NEW upgrades - £10.00 per year. That will ensure that you make money for your work and us idiots out here who need between 50-100 subscriptions ‘may’ afford it! ### 1/5 — Attention *2023-09-16, version 3.4.0* your data may be stolen ### 2/5 — AIは動くが *2023-09-11, version 6.4.0* 全体に動きが不安定。ハングアップした様になって動かなくなる。iPad版とも連携できない。早期の対応を願います。 ### 1/5 — Poco intuitivo *2023-09-11, version 6.4.0* No se entiende nada ### 2/5 — Vẽ *2023-09-02, version 6.3.0* Trưa sư dụng giờ mới mò ### 1/5 — 急に請求 *2023-08-23, version 3.3.0* フリーバージョンだと思って使っていたら急に請求。最初から有料であれば理解できるが大事な企画をし始めてから請求されるのは胸くさが悪い。一万円でも１０円でもいいが有料なら最初から言え。 I thought it was a free version. But after drawing up a few important plans, my plans were taken hostage. Don't show it as free when you’re gonna charge people anyways. I don't care for my 400 yen but it's essentially a scam. These guys lack honesty, it's a shame cuz it's a good product. ## Most critical reviews (10 lowest-rated) ### 1/5 — Japan Rule *2026-08-19* I can’t sign up to this app due to its anti-US rhetoric in its terms of use and policies. It simply states that where theres nuance, Japan rule overrides it, that doesn’t work in the US since if you sell to the country, you are required to follow their rules of engagement. And I won’t accept “we really didn’t mean that… You misunderstood” which is the usual go-to responses. They are also called “Thinkspace” yet have put full stop on any kind of content that might hurt someone’s feelings that might be in some of the research. I have a hard time with this since my research is often challenging. I wouldn’t want my documents deleted or taken down just bc someone from Japan reads it out of context. I had high hopes. **Developer response:** Thank you for the detailed feedback — and honestly, your reading was understandable. Here's a straight answer, not a "you misunderstood." The content restrictions you're referring to were written for a canvas-sharing feature that has since been discontinued — the clauses outlived the feature, and that's on us. By their own wording, they apply to content "transmitted to other Users," not to private canvases. The same terms also state: "We do not own your data. If the data was yours to begin with, it remains yours," and that your content is never used to train AI models. Challenging research is exactly what a thinking tool is for. On governing law: a Japanese-law clause is the standard arrangement for an app operated from Japan — the mirror image of US apps designating California law — and it does not override the consumer protections you're entitled to in the US. We'll clarify all of this in the next revision of the terms. If you'd like to discuss further, please reach out via the in-app feedback — I'm the developer and I read every message. — Naoya ### 1/5 — 오류 심해서 한동안 안썻는데 자동결제 되네요 환불해주세요 *2025-12-10, version 6.4.8* 환불해주세요 ### 1/5 — Shady terms of service *2025-08-08, version 6.4.8* ‘’By using our products, you give the Provider's permission to do certain things with your data’’ I will not be using this app for this alone, but the list goes on! I’ll stick with qrayon’s apps for better privacy. ### 1/5 — I wrote an email but got no response. Rating is just to catch your attention. I'll update it. *2025-07-27, version 6.4.7* Hello! I am using this app and making a tree diagram. The limited version gives me I guess 70 elements to add. Before I go for purchase, it’ll be helpful for me to know the limits of the full upgraded version in terms of how many depth levels can I go, how many elements can I have in each depth, just like the limits on rows and columns of a two dimensional matrix having limits m and n. Also, how many total elements I can fit in the tree diagram (m*n). This info will be really helpful for me in taking the decision. Also, I want to ask if there's a one time lifetime purchase option to skip monthly or annual subscriptions, Id like to go for that in case my requirements are met by the app. Thanks, Naveen K ### 1/5 — bad design *2024-08-28, version 3.4.6* laggy and confusing ### 1/5 — 会员过期之后所有数据都没了 *2024-03-20, version 6.4.7* 会员期间创建的所有画布都消失了也太离谱了吧 会员使用的时候也一直闪退👎👎👎👎👎👎👎👎👎👎 ### 1/5 — 最低 *2024-02-05, version 6.4.6* プロジェクトが終わりそうになったタイミングで課金を要求され、した結果全てのデータが吹っ飛んだ。 お金と時間とエネルギー返してほしい。 ### 1/5 — Sehr zweifelhafte Nutzungsbedingungen *2024-01-23, version 3.4.5* Diese Software sammelt Nutzerdaten unbegrenzt. Nichts bleibt privat. Was ist der eigentliche Zweck dieses Programms? ### 1/5 — そもそも立ち上がらない *2024-01-09, version 3.4.5* ダウンロードするだけ時間の無駄です。 ### 1/5 — Не работает *2023-12-05, version 3.4.2* Выкидывает из программы когда пытаюсь что-то сделать ## Most praised reviews (10 highest-rated) ### 5/5 — Sehr gute App, anfangs schwer zu bedienen *2023-10-10, version 3.4.1* Mir gefällt die App sehr gut, jedoch benötigt es zunächst einige Zeit, um sich vollständig in die Funktionen einzuarbeiten. ### 5/5 — Like it *2023-09-11, version 6.4.0* App มีบักนิด เเต่หาวิธีลบเอกสารไม่เจอ ### 5/5 — 思考整理系のアプリの決定版！！ *2023-06-12, version 6.2.0* 思考整理系のアプリの決定版です。 理由としては ①動作が軽い iPadとApplePencilを組み合わせれば、まるでアナログノートのような軽快さです。 ②いろんな思考法に対応可能 マインドマップやフィッシュボーン方式、マンダラ方式など、思考整理の方法はいくつかありますが、ThinkSpaceは使い方を工夫すれば、ほとんどの思考法に対応できます。 ですが私は、付箋紙を使ってのアイデアだしとグルーピングが、最も有効な思考整理法だと思います。 ThinkSpaceは、付箋紙を使ったアイデア出しの思考整理法をを忠実に再現できます。 ③デベロッパ様の対応が神 アプリの件で問い合わせしたところ、さっそく対応して下さり今回のアップデートでご提供いただきました。 誠心誠意、熱意ある対応はまさに感動ものでした。 ハマる人はとことんハマる神アプリです。 今後とも素晴らしいアプリ開発期待しています。 ### 5/5 — 云同步速度特别慢 *2023-05-28* 图片无法加载 ### 5/5 — こういうツールを探していた！ *2023-04-03, version 6.0.0* 講演用PowerPointのアイディア出し、ドラフト作成にぴったりです！ 骨格を考えながら、思いついたアイディアをどんどん書き足していったり写真素材を貼り付けたりして、清書直前の段階までこのアプリだけでもっていけます。 これからも応援しています！ ### 5/5 — Perfect app *2023-01-17, version 5.0.0* This app is the best app i have never downloaded. I can create my conceptual maps writing by hands and using the lines. Top!!! ### 5/5 — Great tool *2022-11-01, version 4.5.0* Great tool Thanks and congrats to the team ### 5/5 — 이거다 *2022-09-05, version 4.4.3* 세상을 구원할 어플 ### 5/5 — ❤️sooo cute❤️❤️❤️ *2022-09-03, version 4.4.3* البرنامج مراا لطيف ويجنن انصح فيه ### 5/5 — Thank you *2022-07-30, version 4.4.2* That’s the most wonderful man’s mapping app I have ever seen.
