Braintunes vs 4VIDA SYNC

Braintunes is a music app for work, study, sleep, and meditation. If you are looking for music for work, music for study, or calming soundscapes for sleep, Braintunes gives you focused ambient sessions designed to help you stay in the right state without distractions. Choose the mode that fits the moment: Focus for deep work and studying, Relax to unwind, Sleep to slow down at night, or Meditate for quieter sessions. Each session is built to stay in the background with smooth ambient soundscapes, no vocals, and no abrupt changes. Pick the intensity that feels right and let it play without interruptions. Features include: • Focus, Relax, Sleep, and Meditate modes • Three intensity levels • Continuous background playback • Lock screen and native player controls • Sleep timer options • Favorites and disliked-track filtering • Daily reminders and listening streaks • Multilingual support • No ads Built for people looking for study music, focus music, and a calmer alternative to binaural-beat apps.

Sleep, focus, deep calm — with sound generated live from your heartbeat. 4VIDA SYNC doesn't play back a finished file. Every session is created in the moment you hear it — like a live concert instead of a recording. Via Apple Watch, the sound follows your heart rate variability (HRV) and adapts to your nervous system in real time. YOUR BIO-TONE Before your session, 4VIDA SYNC runs a sweep calibration to find the frequency your nervous system responds to most clearly — your vital signature. From it emerges your personal bio-tone, the root note of every soundscape. Same mode, different person, different sound. SMART SESSIONS — SIX MODES WITH LIVE ADAPTATION • REST — drift into sleep • RECOVER — deep regeneration • RELEASE — let go • FOCUS — clear concentration • CONNECT — present and grounded • ACTIVATE — awake and ready With Apple Watch, the audio engine continuously adapts to your heart rate variability during the session — like a good running shoe adapting to your foot. ELECTRIC MOODS — SOUND FOR ALONGSIDE Four moods without ritual: FOCUS, RELAX, SLEEP and MOVE. Switch on, carry on — with a sleep timer for the night. SHARED SESSIONS Listen together: in sync at the same time, with the same reference tone. Or start a partner session with an invite code — two people, even across any distance. WHAT TO EXPECT • Your sound is generated live on your device — no streams, no sample loops • Apple Watch optional, recommended for live adaptation • Headphones recommended — the stereo texture only unfolds on two channels • Sleep timer, "Continue where you left off", Siri shortcut • Dynamic Island + Lock Screen controls • Ambient videos as gentle visual companions YOUR DATA Your Apple Health data stays in Apple Health. Your sound is computed entirely on device. Session results are stored encrypted in your account — export them anytime, or delete your account and data right in the app. PRICE Start free. 4VIDA Plus unlocks everything — 7-day free trial. The subscription renews automatically and can be cancelled anytime in your iOS settings. GOOD TO KNOW 4VIDA SYNC is a wellness product for relaxing, focusing and winding down — not a medical device and no substitute for medical advice.
