Review momentum
ⓘ How we measure thisNew ratings a week
–
Apple's rating count fell over the last 4 weeks: it removed more ratings than came in (spam clean-ups, deleted accounts), so the pace can't be read right now
Lifetime rating
4.8★
recent stars not readable yet: new ratings are a tiny share of the total
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.

About Isochronic
The Isochronic Tone Generator does just what it says: You can create any Isochronic Tone (between 0.01 and 50Hz) with a carrier between 50 and 999Hz.
You can also mix the tone with your own music, set the wave volume in the mix, set a timer (up to 59 mins), program target isochronic frequencies for your brain entrainment sessions, use presets to start easy entrainment sessions and memory slots to put your favorite tones.
As simple as it gets... Enjoy!
FEATURES:
=======
* Variable carrier tone
* Variable isochronic tone
* Fine tune for carrier, isochronic and target frequencies
* Mix the tone with your own music
* Wave volume for better mixing
* Timer (up to 59 minutes)
* Entrainment sessions: Just set the target frequency using the black indicator below the isochronic tone.
* Presets (sleep, relax, awake and meditate)
* Memory slots: for having your favorite tones one tap away
------------------------
Isochronic tones are regular beats of a single tone used for brainwave entrainment. Similar to monaural beats, the interference pattern that produces the beat is outside the brain so headphones are not required for entrainment to be effective. They differ from monaural beats, which are constant sine wave pulses rather than entirely separate pulses of a single tone. As the contrast between noise and silence is more pronounced than the constant pulses of monaural beats, the stimulus is stronger and has a greater effect on brain entrainment (taken from: http://www.mindalive.com/articleeleven.htm)
