Bellhum: Binaural Beats

Focus & study tone sessions

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Stack up to 4 stages, like Beta 18 Hz to Alpha 10 Hz, and Bellhum glides between them with no clicks. Pay once, no subscription. Bellhum makes binaural beats and isochronic tones right on your iPhone. Pick a session for focus, study, relaxing or meditation, put on headphones, lock the screen and keep going. BUILD A SESSION IN STAGES Stack up to 4 stages, for example Beta 18 Hz for 10 minutes, Alpha 10 Hz for 15 minutes, then Theta 6 Hz. Bellhum glides smoothly from one frequency to the next, with no clicks or jumps. GENERATED ON YOUR DEVICE Tones are made live by the audio engine, not looped recordings, so there is no seam and nothing to download. Works offline. MADE FOR HEADPHONES, FINE ON SPEAKERS Binaural beats need stereo headphones; a quick ear check plays a tone in your left ear, then your right. No headphones? Switch to isochronic tones, which work on the speaker. YOUR MIX Pure mode plays only the beat. Or add a soft background: pink noise, rain, brown noise, ocean, wind or hearth. Keep playing over your music or podcast if you like. BACKGROUND AND LOCK SCREEN Sessions keep playing with the screen locked, with play and pause on the Lock Screen. Calls pause the session and it picks up again after. A GENTLE STREAK Listen 5 minutes or more on a day to keep your streak. Journey shows your week and history. FREE AND PRO Free: single-stage sessions, 5 built-in sessions, 2 saved sessions, pink noise and rain, timer, ear check and streak. Bellhum Pro, one-time purchase, no subscription: up to 4 stages per session, 4 built-in multi-stage sessions, unlimited saved sessions and 4 more background sounds.
