Mobile App

Release status

The mobile release is in preparation. The instructions below describe the candidate app; physical device acceptance is still required before release.

Listening

Use stereo headphones at a comfortable volume. Read the session instructions before playing. Bluetooth speakers and casting do not preserve a separate tone to each ear in the way headphones do.

Phone Torch

Optional flashing light

Enable Photic Mode in Account to reveal the player controls, then complete the light screening. The torch starts only after you choose it in the player. It remains off if the required native control is unavailable.

Limits and risk

Flashing can trigger seizures, migraine and discomfort. Closed eyelids do not eliminate this risk. Software requests are capped at 40% duty and 30 ms per pulse, but actual timing and optical intensity depend on the device. No universal safe distance, brightness or frequency is established by these limits.

Stopping

Tap the torch control again to stop. Pause, backgrounding and navigation stop light too. Do not combine the phone torch and headset. If the light behaves unexpectedly, stop using it and contact support.

LED Headset

Connection and activation

Complete the light screening before scanning. Connect a supported headset and explicitly enable it in the player. A remembered connection does not enable light automatically. Follow the instructions for the tested headset model and firmware.

Timing

The headset follows the authored light schedule, which can differ from the audio beat frequency. Stop behavior after Bluetooth loss depends on the headset firmware and must be verified before that model is supported.

Offline Audio

Downloads

Download a session while online, wait for completion and check it is available before going offline. A download is not complete until the file has passed validation. Premium access is still required for paid sessions.

Storage

Downloads use device storage. Old audio revisions are ignored when a verified revision changes. Progress is stored locally and is not a cross-device backup.

Builder and Infusion

Builder

Open Create, then Build tones. Choose a steady tone pair or a timed sequence. You can add a noise background. Create a track up to 60 minutes, subject to the creation allowance available to your account.

Infusion

Open Create, then Infusion. Choose an MP3 you own or have permission to upload and modify, up to 50 MiB. Select a tone pair, blend and output duration. The file is uploaded for processing and may repeat or be trimmed to the requested duration. Infusion does not add a spoken guide.

Your library

Completed custom tracks appear in Library. If creation is unavailable or a usage limit is reached, the app shows an error. A failed request is not proof that a track was created.

Your Account

Subscription terms

The checkout or store purchase sheet displays the price, billing period and renewal terms before purchase. Store purchases and restores require verification before access is granted. The approved launch proposal is $14.99 per month; paid release is still in preparation.

Cancellation and deletion

Manage a web subscription in billing settings and an Apple or Google subscription in the corresponding store. Account deletion closes access and requests data cleanup; store subscription cancellation is a separate step. A pending cleanup status means the deletion process has not fully finished.

Ready to Meditate?

Explore the written practices while mobile release testing continues

The Gateway is not a medical device and does not diagnose, treat, cure or prevent disease. Use stereo audio at a low, comfortable volume. Optional flashing light can trigger seizures, migraine or discomfort, including without a known history. Screening and closed eyes do not eliminate that risk. Read the light warnings before enabling it and stop if you feel unwell.
