clir Focus vs Demixr

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.

Demixr is a web service for processing audio, with tools for separating vocals and instruments, removing reverb, marking speech, and analyzing BPM and key. Its Pro 1.5 vocal separation has Voice mode for complex mixes, live recordings, or speech over music, and Music mode for songs and covers or separating vocals from accompaniment. A separate stem tool uses Demucs to split music into vocals, drums, bass, and other parts. For dereverb, Demixr recommends isolating vocals first; applying the effect to a mixed track can cause artifacts or distortion. VAD provides editable speech-segment markers and batch export, though detection may be inaccurate with quiet vocals or noisy recordings. BPM analysis includes tempo, key, and Camelot values, with optional tap-to-sync. The free plan costs nothing and includes 10 minutes of audio monthly, a 10 MB upload limit, two VAD uses, queued processing, and no WAV downloads. Paid one-time plans start at $4/mo, without automatic renewal. Uploads and outputs are deleted within 24 hours by default.
