Please consider adding this extremely important feature. ### 4/5 — ios客户端输入用户名bug *2026-06-17* 如题 ### 5/5 — Good app *2026-04-05, version 3.6.3* Notion like app but also for offline use and more flexible. ### 1/5 — Unable to sync files without access *2025-08-18* Please support IAP on iOS/macos instead of stupid online account ### 1/5 — Can’t sync with iCloud *2025-07-07* Garbage App. Can’t sync with iCloud. Also requires you to pay for THEIR sync. App is also very clunky at best. I’d rather use Obsidian. ### 1/5 — Does not work with selfhosted Siyuan *2025-04-05, version 3.1.26* I Like Siyuan, the PWA is Not the same. ### 5/5 — Швейцарский нож среди приложений для заметок *2025-02-27, version 3.1.22* Качественное приложение без подписок. Но платная функция синхронизации. Синхронизироваться можно и к себе в S3. Поддерживает задачи, таблицы, карточки запоминаний, AI-помощник, агенды на день, встроенный SQL. Но каждая из этих функций работает не совсем идеально :) И при этом, наверное, лучшее приложение для ведения больших записей и собственной базы знаний. ### 5/5 — Perfect app *2025-02-10, version 3.1.20* This app contain all feature that i need It like the combine of Notion + Obsidian + Anki You can use it offline and manual sync, or online syncing through Syuan host (purchases required - and I never regret buying this), recommend for everyone!! Thanks to developers so much!! ### 5/5 — Love this *2024-12-08, version 3.1.14* Really well made, still learning to unlock more possibilities. ### 4/5 — Buggy on iPad but an almost perfect Notion alt. Never going back *2024-10-04, version 3.1.8* On Mac, perfect. On iPad, the experience is very buggy and clear the app was not built with iPad in mind. I hope there will be a truly native app or a more logical experience for iPad. Having to double tap everything and jumping screen elements and more make it unusable for me right now which is disappointing as iPad is a much more practical device to use for me. Improvements soon I hope. ## Frequently asked questions about SiYuan ### What is SiYuan's primary function?
