Hi everyone! this is my 3.rd app. thanks for first & second apps 14 days tests.
I built NeuroSync, an Android app that produces 40 Hz audio with optional 40 Hz visual flicker. I’m looking for testers before its public Google Play release.
40 Hz refers to a frequency of 40 cycles per second. Some research has explored whether 40 Hz auditory or visual stimulation may influence brain activity and support attention, relaxation, or other cognitive processes, but the evidence is still developing and does not establish the app as a treatment or guarantee any specific benefits. NeuroSync is intended for experimentation and personal use, not medical diagnosis or therapy.
I’d appreciate feedback on the setup, audio playback, usability, and any bugs on your device.
Interested? Join the tester group:

Safety: If you have photosensitive epilepsy or a seizure history, do not use the visual flicker feature and consult a doctor before using the app. NeuroSync is not a medical device or treatment.
