Include your app version, device model and the steps that led to the issue. Please avoid sending private formulas or a full backup unless necessary.
Getting started
Create a project in the recipe library. Add ingredients and steps, branch from any existing version, and record each trial. Templates define the fields you want to fill in; you can also begin without one.
The current app interface is in Simplified Chinese. English store information does not imply an English interface.
Back up your notebook
Open Tools (工具) → Local backup (本地备份) → Export full backup (导出完整备份). Save the file somewhere you control. Unfinished drafts are not exported. Import adds records without replacing your existing notebook.
Erase local data
Open Tools (工具) → About & Privacy (关于与隐私) → Erase local data (清除本机数据), then confirm. This deletes your notebook, custom templates, drafts and internal recovery files. Exported files outside the app must be deleted separately.
Offline and free
No account, subscription, ads, cloud sync or online AI is required or included. File sharing uses the destination you explicitly select in your operating system.
Scope of the tool
Formula Notebook records your work. It does not establish recipe safety, validate experimental conclusions or provide certification for regulated work.
