I built Bookm8 β a retro synthwave bookmark manager that actually makes organizing links fun: * Kanban-style organization (drag & drop your bookmarks) * Map view for location-based bookmarks * Search & filter through all your saved links * Offline support β works even without internet * 6 themes (but letβs be honestβ¦ synthwave is the GOAT) * Easy sharing β share bookmarks from any app to bookm8

Verdict
The clearest difference is in-app purchases: Bookm8 at none against SpoolTool's 1. Bookm8 also leads on iOS requirement (15.0 vs 26.0). On price, update cadence, ads and device support there is nothing between them.
