## What is GUGA?

GUGA is a hyper learning tool that can meet your learning needs in different scenarios.

“Notebook”, “Whiteboard” and “Cards” are the three most important functions of GUGA. 
In addition, GUGA also provides users with a community-SharePlace to share learning data; and provides a "Inspiration Shorthand" function to send data and record information across devices; and GUGA also provides a large number of shortcuts for you to use after connecting to the keyboard mouse.

The “Notebook” is the most common learning material and the most basic learning scenario. GUGA's notebook: 
1. Not only other notebook software, but also support a variety of formats to be imported into notebooks, create new notebooks, add/reduce pages, provide more than 100 inner pages and cover templates, DIY outline catalogues, edit page jumps, import pictures/text, etc. 
2. It also supports adding an unlimited number of handwriting layers to each page of the notebook, hiding/displaying/merging handwriting layers, which is convenient for brushing questions and other uses when learning. 
And, 3. You can also long press to select the content on the notebook to mark/excerpt while writing and taking notes, and make cards for other uses based on the excerpt content. 

The “Whiteboard” is a multi-data learning console and a richer learning scenario. GUGA's whiteboard: 
1. Support the import of multiple notebooks and use them in one whiteboard at the same time. You can also add/import data in other formats to learn and use them together. 
2. Provide a notebook floating window system, which makes it more convenient for you to use multiple notebooks and whiteboards at the same time. The notebook in the whiteboard can be presented in the form of a floating window. The floating window has a variety of states (maximizing/mini window/up and down left and right side windows), which can hide/close/display all floating windows with one click; support floating window memory, type again Open the whiteboard, and all floating windows that are not closed can continue to be used. 
3 Provide the "multi-level" whiteboard function. The whiteboard can create a lower-layer whiteboard, or it can be connected with other whiteboards to form a link relationship, thus creating a relationship between learning scenes. 
4 You can copy the selected content in the floating notebook to the whiteboard to form a card. The cards on the whiteboard can be freely combined and split, and the cards can also be connected to form a brain map; the jump relationship can be set between the cards. 
5 The whiteboard can be divided by frame, and it can also be positioned with pins to make it easier to use and manage the whiteboard content. 
In addition, 6 The entire whiteboard can be emitted as pdf, and the frame can also be emitted as a multi-page PDF, and the jump relationship between the frames will also be retained.

The card is the achievement of atomization learning, and the card package is the collection of your achievements. GUGA's card: 
1. Excerpt cards in the notebook and cards on the whiteboard can be collected in the card package. 
2. You can use the "Inspiration Catcher" function of the GUGA WeChat official account/browser's GUGA plug-in to transfer the information you want to save to any of your card package at any time. 
3. Each card is a "blocked" rich text editor, which can be combined and split on the whiteboard, or any block can be set as an answer block in flash card mode. 
4. Card packs can be converted between ordinary packs and flash card packs; the function of flash card packs is consistent with other flash card software (Anki). 
5. Each flash card pack can choose different learning modes and different memory algorithms to help you better learn and review cards. 
In addition, 6. The daily learning plan of flash cards will automatically appear in the GUGA log (My Logbook) on the right to learn flash card packages at any time.

Have Fun with GUGA 2.0, and Enjoy Your Serious Learning Power.

### 5/5 — 有一点小问题

*2026-03-07, version 2.0.38*

荧光笔的方向不会随着pencil的转动而转动，并且每次方向是随机的，想要调方向就要转动笔的朝向，不太好用。

### 1/5 — I can't accept your Terms

*2026-01-08*

I use iPhone 15 Pro. When I open this app first, I can't check Terms and Privacy Policy. please fix it.

### 1/5 — 无法登入

### 4/5 — One Suggestion

*2025-10-18*

I love everything about this app so far. I am a heavy users of GoodNotes and MarginNotes. I use both of the apps for note taking and study. What I like about this note taking app is it’s user-friendly, it has a white board for mind mapping, and flashcard for studying. I did not get to test white board and flashcard to study yet but this app is very promising. 

One suggestion I have for the developer is if you could allow Apple Pencil to be able to transition from one tool to the previous tool used. The current default setting is it switch between pen and eraser. But for me I rarely use the eraser because you can undo with two taps. I switch my pen a lot more from black and red so it would be huge if you can do that here.

Thank you for the amazing work! and thank you for taking the time to hear my feedback!

### 5/5 — Perfect for me

*2025-07-01, version 2.0.31*

So happy to have found this. It just works exactly how my brain does. Love the weight of the pen stokes, the simplisity, the nesting of notes. Really well designed and considered app - Perfect for me and rare not have a subscription model. Love it ❤️

### 5/5 — 喜欢

*2025-02-23, version 2.0.31*

好用，不会拖慢iPad的速度

### 4/5 — iCloud Sync glitchy

*2025-01-29*

I really enjoyed this app but the cloud sync function seems to be glitchy often. Some of my files are not synced between my two iPads even though both are showing synced to the cloud and some of my notes would get erased if I switch my device. Other than this, great app.

**Developer response:** Hello, the iCloud synchronization problem team will continue to optimize, please keep up to date.

### 5/5 — 👍👍👍

### 1/5 — 所有笔记都消失了

*2024-12-14, version 2.0.30*

本来因为喜欢笔触和无限画布买了永久会员，还写了有很多白板，都是很珍贵的笔记，icloud备份啥的都开着，上半年用过，因为我两个设备都开着，本地都存了笔记的，以前一直用没啥问题。然后有半年不用了，今天想起来看看我的笔记，点开第一眼还晃了一下以前的笔记们，然后就闪进重新登陆界面，登陆之后发现：1. 我成免费会员了 也不知道上哪找回我的购买，也没找到反馈或者售后按键 2. 笔记全部清空了，一片空白等着你。。。绝望，愤怒，不解，有什么解决方案吗？
