What's the best iOS app for organizing ideas and inspiration for personal projects?

Pinterest is a go-to platform for visual discovery and project organization. It serves as a digital corkboard where users can save, or 'pin', images and ideas from across the web into thematic collections called boards. For someone planning a home renovation, for instance, they can create boards for 'kitchen ideas', 'paint colors', and 'lighting fixtures', visually consolidating inspiration in one place. The app's search functionality is notably precise, often returning highly relevant visual results that help users drill down into specific styles or items. A key feature is the 'More Ideas' section, which suggests related content based on a user's existing pins, continuously surfacing new inspiration. However, some long-term users report a persistent bug where the quick-add pin button in this section occasionally fails, requiring a full open of the pin to save it, which disrupts the streamlined workflow. Reviews indicate the platform excels at offering a wide range of content, from high-end design to affordable DIY solutions, catering to various budgets and tastes. While the core experience is strong for collection and discovery, some community features like a native 'repost' button are absent, which users have requested for sharing relatable finds more easily.
