The most advanced full-fledged SGF viewer and editor on iOS devices, seamlessly integrated with the web to support downloading of unlimited and most fresh professional go games, with a clean and simple user interface. + Deep integration with the professional go database from go4go.net so that you can access latest professional games by just a tap from go4go's rich resources, and search the desired games from the database by criteria like player names and tournaments, etc. + Clean and simple UI built on top of the deep technologies and elegant iOS platform. You can replay games in normal plain flat board with color or black/white mode, 3D perspective view, or browse the game like reading a real book. Even you can view the game with real 3D go ban model through Argument Reality technologies (available for devices running iOS 11+). + Web integration goes beyond browsing go4go database to support downloading games from any web site with SGF links. You can use the in-app web browser to view a web site with SGF resources and download them into your device with a tap on the link. Even with running games which are updated in remote server from time to time can be downloaded and updated with pull down gesture. The in-app browser supports downloading games from links to a single SGF file, or a Zip/RAR archive. + Local games downloaded or created manually can be organized in groups. Games starred are kept in favorite page. Games deleted are protected by keeping them in trash folder until you decide to delete them permanently or restore them back. You can search games by user names or tournament names in local game resources. + Full SGF editing features for complex SGF games with variations and comments. You can also transform the games by flipping and rotating a game. Scoring an end game is provided. + Support AirPlay with a new board viewing scheme mirroring on big TV screens. + Including image recognition for user to generate SGF from images. Work for computer generated board images with 90%+ recognition rate. Support real life board photos from 1.8.0 version. But don't buy if only for this feature as it is not the most advanced image recognizer now (was in its early release). + Many features hidden in small details. You can play with the settings and find many handy small shining things. The nearly 10-year old app was updated and polished continuously, with inputs from various go fans all over the world. Let's keep the go app standard high together. ## Key features - Professional Go game database integration - Multiple viewing modes (flat, 3D, AR) - Download games from web SGF links - Local game organization and management - Full SGF editing with variations and comments - Image recognition for SGF generation ## Recent user reviews (10 of 25) All indexed reviews: https://appshunter.io/ios/app/go-eye/id562516957/reviews.md ### 3/5 — Go4Go的棋谱怎么叕打不开了啊？ *2026-02-25, version 3.9* 如题 ### 1/5 — Useless *2024-04-10, version 3.8.6* Four out of 5 features are in Chinese or Japanese language only. One feature presents pro games, mostly from Korea and China leagues. Top pro tournaments like Honinbo or Kisei are not presented The replay mode is very unpredictable. Sometimes jumps some 50 or more moves forward. Wouldn’t buy it again. ### 1/5 — Deceptive marketing do not buy *2024-04-09, version 3.8.6* This app is basically unusable if you don’t speak mandarin and is not integrated to go4go archive. I got this because there was no go4go app for iPhone, but on the actual app it’s just links to free publicly available databases e.g. fox Weiqi, and archives in mandarin. Considering the advertising this is a deceptive way to rip you off for 20 quid ### 5/5 — Great app! *2022-11-25, version 3.8.6* Very useful and convenient app for studying professional games! But I wanted to know if I can change a language in the app? Thank you! ### 5/5 — Great App *2022-11-11* I use it every day to download professional games from go4go and review. ### 3/5 — 拍照儲存到sgd功能 *2022-10-31, version 3.8.6* 拍照儲存到sgd功能幾乎不可用，你們有測試過嗎？現在市場上單識別棋子的能力已經很高，請問可以改善一下嗎？ ### 3/5 — Unable to receive help from developer. *2020-03-30* For some reason, my original review has been removed from here. I tried emailing the developer three times now, and each time it comes back “return to sender”. He seemed responsive after he replied to my review, but now I’m unable to contact him about my issues with the app. Unable to give a better rating until this is resolved. **Developer response:** Updated: Mail service recovered. Please try to send email again. (Shortcut: Use Go Eye/About/Feedbacks to auto fill the email address and app version). -----Old response----- To seek immediate help, you could send to feedbacks@goeye-app.com. But anyway, I will answer the questions here. First of all, most questions are caused by being new to Go Eye. Let's jump to answer quickly. - "Importing games is a pain! " There are at least 10 more convenient ways to import but you only use the most painful way. It supports importing SGFs(Single SGF file, zipped or tar'ed)from airdrop, dropbox, email attachment, iTunes (which might be obsolete on new Mac after Apple updated iTunes), and web page by tapping the SGF URL(zip/tar links as well) link directly in one or two seconds! Let me know if you get problems doing all these. e.g., open your iOS filer, tap the SGF file and choose "Copy to Go Eye" - "The tree view doesn’t scroll to the current move automatically as I play out variations" - There is an option in settings which enables the "auto show variations" (Session 2 in settings). "when modifying variations, you can only delete one move at a time" You can long tap the variation icon, when the icon shakes (like deleting an app in iOS desktop page), tap "-" to delete a variation. -"the stone numbering system is broken, as stones played in spots that had previously been occupied (like in a koi fight) are given the number of the stone that was previously there". Not sure what screen you are referring, in the main board page, it shows current number. In book page view, as it shows the ko chain, it will show the earliest number. Please give an example through email or other ways. -Overall, the entire UI is cumbersome compared to apps that cost much less. I can say most people love Go Eye because of its beautiful UI. -you cannot organize games into folders, but rather into “groups”, which can’t be reordered once created. Extremely inconvenient for organizing games. You can reorder them by dragging, or selecting games (press edit to enter editing mode for game list) and move them to other groups easily. -The Augmented Reality view and 3D views are neat, but not very useful, and you can’t zoom to make to Augmented reality table larger or smaller, which is also ridiculous. For AR, you need to zoom in your device instead of gesture! -The “help” section is severely outdated, with pictures and iconography from previous versions of the app, which makes it almost useless in learning the functionality. Apologize for the outdated help. This is a big problem of Go Eye. It has little document on its richest features. Most of the great features and small details are to be discovered by users or by asking the developer through emails. Will try to have a great document of Go Eye in the future. -- All in all, I very much regret purchasing this instead of EasyGo Pro, or even SmartGo Kifu, which is more expensive. The ONLY advantage of this app is that it has good integration with websites like go4go for following professional games. Perhaps this app is really only for that purpose, but if that’s the case, no need for it to be so expensive. For reviewing and annotating your own sgf’s,, it is very unsatisfactory. I hope that you will feel lucky instead as you buy a better app with half price after you discover the greatness of Go Eye. Most users love it and gave very high ratings. Thanks. P.S. I really appreciating your posting the detailed descriptions of the problems instead of just rating one 1-star and leaving a brief ambiguous bad comments :) ### 5/5 — 超優質軟件 *2020-01-19, version 3.7* 最棒的記譜，看譜工具。 與 dropbox 與 圍棋老師(AI) 可完美結合。 輕鬆導入sgf 棋譜，可自訂每頁棋譜手數，像看棋書一樣的舒服。 ### 5/5 — 部分按鍵沒顯示 *2019-10-15, version 3.6.3* 部分按鍵沒顯示，但是按了仍有反應，請儘速修正，感謝🙏 ### 5/5 — J’aime *2019-05-19, version 3.6.1* Très bonne appli cependant depuis que j’ai un clavier en coréen, Go eye se met entièrement en coréen.
