Step inside your mind. Foggy mornings, wired midnights, the 3 PM crash in between, your brainwaves are stuck out of sync, and sound can shift them back. Science-backed binaural beats guide your brain into deep sleep, sharp focus, calm, recovery, or states beyond ordinary awareness. No meditation. No pills. Just headphones and 15 to 60 minutes. Stanford neuroscientist Dr. Andrew Huberman has publicly discussed 40 Hz gamma binaural beats as a tool for focus and concentration. That is the science Brainwaves is built on. 7 BRAINWAVE BANDS, DELTA TO EPSILON Delta for deep sleep. Theta for dreaming. Alpha for calm. Beta for focus. Gamma for peak cognition. Epsilon for deep transcendence. SIGNATURE SESSIONS Deep Gamma Focus (40 Hz Gamma): sharp attention and working memory. Deep Sleep Night (Theta): drift into deep sleep faster. Ultra Sleep System (Delta 2 Hz): slow-wave sleep for physical restoration. Nervous System Reset (Alpha 10 Hz): calm stress, restore balance. Flow State Engine (Alpha 11 Hz): peak flow for deep work. Serotonin Release (Alpha 10 Hz): lift mood, ease tension. SLEEP AID AND INSOMNIA RELIEF Fall asleep faster and stay asleep. Delta journeys (0.5 to 4 Hz) for racing thoughts, 3am wake-ups, stress, late-night screens, and jet lag. A drug-free sleep aid for people who have tried everything. FOCUS AID AND BRAIN FOG Cut through fog with beta and gamma sessions (13 to 40 Hz). Sharpen clarity for deep work, study, and mental fitness. ANXIETY CALM AND STRESS RELIEF Alpha and theta soundscapes (4 to 12 Hz) ease tension and rebalance your nervous system. No meditation experience needed. HEALTH AND RECOVERY Solfeggio frequencies layered with brainwave audio for whole-body reset and recovery from burnout. CONSCIOUSNESS EXPERIENCE, EXCLUSIVE TO BRAINWAVES Beyond sleep and focus, Brainwaves is built for altered states of consciousness you will not find in other brainwave apps. Astral Projection: guided exploration beyond the limits of the physical. Remote Viewing: expand perception beyond ordinary sight and strengthen intuition. Lucid Dreaming: become aware inside your dreams and learn to steer them. Fifth Dimension: transcend ordinary perception. Gamma and Epsilon Journeys: expanded awareness and deep transcendence. 963 Hz Pineal Gland Activation: the God Frequency, for deep meditation, whole-brain coherence, and higher states of awareness. WHY BRAINWAVES 500+ precision sessions across sleep, focus, relaxation, spiritual exploration, and health. EEG-mapped frequencies: science-informed design, not random tones. Personalized journeys: tell us your goals, we guide your first session. Offline listening and Family Sharing: download favorites and share with your family. Free trial: try it before you commit, cancel anytime. WHAT TO EXPECT Night 1 to 3: the beat gives your attention somewhere to go, so it is easier to switch off. By day 4 to 7 you reach sleep, focus, or calm faster, and from week 2 the state holds longer. Individual results vary. WHO IT IS FOR You have tried meditation apps and they did not stick. You want a drug-free sleep, focus, or recovery aid. Brainwaves was made for you. SAFETY Headphones or earbuds are required. Do not listen while driving or operating machinery. SUBSCRIPTION TERMS Begin with a free trial. Your subscription automatically renews 24 hours before the end of each billing period and is charged through your iTunes account.

Verdict
The clearest difference is review sentiment: Brainwaves at 76% against PDF Editor・PDF File Converter's 18%. Brainwaves also leads on ratings volume (3.3K vs 154) and update cadence (weekly vs every 3 weeks). PDF Editor・PDF File Converter's advantage is rating (4.7 vs 4.4). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Brainwaves sells 10 in-app purchases, starting at $12.99 per month and PDF Editor・PDF File Converter sells 10 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.
PDF Editor・PDF File Converter holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Brainwaves has 3.3K ratings behind it against 154, so its average is the more settled of the two. Written reviews complicate that: 76% of Brainwaves's written reviews are positive against 18% of PDF Editor・PDF File Converter's, so the app with the better star average is not the one people write more warmly about.
Brainwaves ships an update weekly, PDF Editor・PDF File Converter every 3 weeks. The most recent releases landed on November 8, 2026 and November 7, 2026 respectively.
