clir Focus vs VocalDrop

clir Focus is an iOS audio focus app designed for people with ADHD who work in headphones. It processes sound on the iPhone in real time and sends it to connected headphones. Its AI filters voices while retaining softened ambient sound, and users can layer white, pink, or brown noise and binaural beats over that sound. The privacy policy describes Original, Ambience, and Speech listening modes.

Sessions are structured before the first task, without streaks, countdowns, or scorekeeping. Microphone audio stays on the iPhone: it is not uploaded or stored on a server and is not used to train AI models. The maker says data in transit is protected with TLS and stored data with provider access controls and industry-standard safeguards. Users can sign in with email, Sign in with Apple, or Google; Apple handles distribution and payment processing. The first three sessions are free at free. A monthly subscription is available, but its exact price depends on country and is shown in the App Store before a charge. The maker is based in Graz, Austria. clir Focus is a focus tool, not a medical device, and does not diagnose or treat medical conditions.

VocalDrop is a free desktop app that uses AI to separate vocals from songs stored on a computer. A separation can produce both an isolated vocal and an instrumental stem, for uses such as sampling, remixing, editing, or karaoke. Fast and Max modes use RoFormer-family models, with different models available for some hardware. The app can also extract audio from video, separate it, and place a selected stem back into a synchronized video. Users can paste links from YouTube, SoundCloud, Vimeo, TikTok, and more than a thousand other sites for fetching. Optional processing includes denoising, AI vocal restoration, silence removal, and audio-format conversion. The maker says track contents are processed locally and not uploaded. Separation can run offline after the required model download; enabling NVIDIA acceleration also downloads a one-time CUDA package. A command-line interface with JSON output supports pipelines. VocalDrop runs on Linux, macOS, and Windows, and its free plan lists no track limits, watermark, account requirement, or feature paywall. The maker says current builds are not code-signed or notarized and provides SHA-256 checksums for release assets.
