What Idea Think is
Idea Think is an iOS and macOS app for capturing ideas and arranging them into branching trees shown through an interactive Tree Map. New ideas can remain in a Pending inbox until they are placed into a tree. Search supports keywords, tags, and depth filters, helping users locate items within an idea library. The app works offline and exports libraries as PDF or JSON; an individual tree can also be shared as a PDF. It supports English, Japanese, Traditional Chinese, and Simplified Chinese. Ideas are stored on the device, with no account, cloud synchronization, analytics, crash reporting, or app network requests described by the maker. The free plan costs nothing and includes capture, branching, Tree Map viewing, search, tagging, PDF export, and offline storage. Ads support the free app. An optional IdeaThinkPro upgrade adds horizontal and mind-map layouts plus per-idea reminders, with no price listed.
