25-year dev builds native Mac app in a day by talking to Claude
A developer with 25 years of experience spent roughly a day talking to Claude through a microphone and produced Dropper, a native Swift menu bar app plus its companion website built on Next.js and . The app lets users drop any file onto the menu bar icon; it uploads to the user's own and puts a shareable link on the clipboard automatically. It includes waveform players for audio, a real video player, markdown rendering, and a built-in screenshot and annotation tool.
There are no accounts and no — files stay in the user's own . The developer attributes the speed not to the AI itself but to their own experience: knowing the exact , edge cases, and quality bar meant they knew precisely what to ask Claude for. As a result, the codebase includes unit tests, a code-signing and notarization release pipeline, and even a headless debug CLI.
The source code is available publicly so others can judge its quality themselves.
