I got tired of jumping between browser tabs to format JSON, test regex, convert colors, and hash strings. So I built Devly. 50+ dev tools in your macOS menu bar. Click, pick, copy, done. Encoding, hashing, JSON/YAML/XML, color converter, regex tester, diff tool, and more. Pure SwiftUI, fully local, no internet, no subscriptions. $4.99 one-time, macOS 13+.

MindHalo transforms the way you study. Turn any text into organized study guides, build flashcards with one click, and get real explanations from an AI tutor powered by Apple’s on-device intelligence. Everything works privately on your Mac, with no data ever leaving your device.
