Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
OSCION
Read full descriptionHide full description
Oscion is an intuitive, interactive real-time generator for binaural beats and pure tones. Two ways to listen: Binaural beats (headphones recommended) Binaural beats are an auditory effect that can occur when each ear hears a steady tone that is slightly different in pitch. Your brain may perceive a subtle beat at the difference between those tones. Because each ear needs its own tone, headphones are recommended. Pure tones (headphones or speakers) Set the beat frequency to 0 Hz to produce a single steady tone. This does not rely on a left/right difference, so it works through speakers or headphones. Clean, precise control: Oscion is designed for direct experimentation. • Adjust beat frequency and base frequency in real time. • Set a session length with the built-in timer so you don’t need to watch the clock. • Use the Transition feature to glide smoothly from your current tone to a different tone over a chosen duration. • Listen to Oscion on its own or while other audio is playing. Presets: Oscion includes binaural beat and solfeggio frequency presets along with the ability to create and save your own custom presets. No internet connection required: Oscion does not require an account and does not stream audio from a server. Everything runs locally directly from your device.

You can find plenty of Solfeggio music and healing audio tracks on video streaming sites, but it’s hard to tell if they actually produce the frequencies you’re looking for, isn’t it? Plus, most of them are just boring. With this app, you can reliably combine multiple frequencies tailored to your needs at any given moment and listen to them while playing music or videos. Since it uses binaural technology to generate fluctuations like alpha waves and Schumann resonance, using headphones or earbuds is most effective. Please adjust the volume so that the sound is low enough not to interfere with your music. For example, during meditation, you can use 174Hz + 963Hz + 4096Hz + theta waves; for sleep, the highly therapeutic 285Hz + 396Hz + 528Hz + delta waves; and when you want to focus on studying or work, 432Hz + 741Hz + 852Hz + Schumann resonance—you can create various combinations to suit the situation. In addition to a total of 11 frequencies, there is a mode modeled after a singing bowl. However, on older iPhone models, enabling too many frequencies at once may cause noise. If this happens, please reduce the number of frequencies you mix. You can use all features during the 10-day free trial period. Even during the trial, you can purchase a lifetime license at any time using the button at the bottom of the screen. Please scroll down if it is hidden. Feature Description: - You can synthesize the following Solfeggio frequencies: 174Hz: Expansion of Consciousness 285Hz: Natural Healing Power 396Hz: Release from Anxiety 417Hz: Embracing Change 528Hz: Love, Miracles, DNA Repair 639Hz: Harmony from Conflict 741Hz: Improved Expressiveness 852Hz: Enhanced Intuition 963Hz: Higher-Dimensional Consciousness 432Hz: Stress Relief & Focus 4096Hz: Angelic Frequency Bell: Singing Bowl Mode - In Singing Bowl Mode, up to three harmonics (2.7x, 4.3x, 5.8x) of the active frequency are synthesized. Since the Angel Frequency is a high-frequency sound itself, Singing Bowl Mode is disabled for it. - Tap the waveform display to view a list of frequencies, allowing you to select a frequency while confirming its effects. - Tap the “i” button to display the frequency details dialog. Details are displayed one item per page, so swipe horizontally to find the item you want. The latter part also includes explanations of Schumann resonance and delta to gamma waves. - The left-right phase difference (modulation) can be set from 0 to 50 Hz in 0.01 Hz increments. If set to 0 Hz, the left and right channels will have the same frequency, allowing you to play pure Solfeggio frequencies. - You can set the following fluctuations with a single tap. Since the frequency is set to approximately the center of each frequency range, please use the ±0.01 buttons for fine-tuning. • δ waves 2 Hz (less than 4 Hz): Brain waves that appear during deep sleep. They contribute to cell repair and strengthening of immune function. • θ waves 5.5 Hz (4–7 Hz): Brain waves that appear during light sleep, such as REM sleep, or during deep meditation. They contribute to memory formation when absorbing new information. • Schumann Resonance 7.83 Hz: The Earth’s natural frequency. Effective for stress relief. Synchronizes consciousness with the Earth. • Alpha waves 11 Hz (8–13 Hz): Brain waves that appear during relaxation or meditation. They indicate low stress levels and a calm, composed state of mind. • Beta waves 22 Hz (14–30 Hz): Brain waves that appear during wakefulness and concentration. Excessive beta wave activity can cause stress and anxiety. • Gamma waves 40Hz (30–80Hz): These brain waves are strongly present when multiple neural networks are active simultaneously. - Use the gear button to save up to five named combinations, which can be restored with a single tap. To rename a combination, tap the text field.

Verdict
The clearest difference is in-app purchases: OSCION at none against Solfeggio Mixer's 1. OSCION also leads on update cadence (every 2 weeks vs every 2 months) and iOS requirement (13.0 vs 17.6). On price, ads and device support there is nothing between them.
