## What is Sleepgod?

Nature sounds for a calm night.

Sleepgod is a relaxation app that layers binaural beats over soothing nature sounds.

Waves on the shore. Wind drifting through a forest. Soft rain on a quiet night. Choose tonight's sound, put on your earphones, and let the night settle in.

- Binaural beats layer with independent volume control and on/off
- Sleep timer (15-90 min) with gentle fade-out
- Wake-up timer (15 / 30 / 45 / 60 / 90 / 120 min) — at the set time, a gentle alarm plays over the nature sound
- Background playback
- Dark, night-friendly design

About binaural beats:
A listening experience created by delivering slightly different frequencies to each ear, producing a gentle "beating" sensation.
Our binaural beats are designed around frequencies based on just intonation, known for its beautiful resonance, and gradually guide you into the beating.
Let yourself rest in the beating and the subtle fluctuations, and feel a deep sense of relaxation.
Stereo earphones or headphones are recommended.

This app is intended for relaxation and is not a medical device. Please use at a moderate volume.

### 5/5 — 想像以上の効果

*2026-08-30*

普段から寝付きが悪く試しにダウンロードしてみたのですが、想像以上の効果で大満足しています。
流れてくる独特な音波（？）のようなサウンドがすごく不思議で、聴いていると頭の緊張がじんわりほぐれていく感じがします。いつもはベッドに入ってから長いと1時間近く寝付けないのに、これを流すと気づいた時には落ちていました。翌朝の目覚めもスッキリしていて重宝しています。

### 5/5 — 眠れる様になりました

*2026-08-27*

私は眠れないと羊が１匹羊が２匹と数えたり，トイレにばかり行って困っていましたが雨の日は割と眠れていたのでアプリをインストールした日の夜は雨の音を選びました。雨が降ってきたなぁと思っていたら雷が鳴り5分位は聴いていたと思いますが眠ってしまいました。
次の日は仕事が休みだったので、カエルの声を聴きながら昼寝をしました。丁度良い具合に３０分で目が覚めてすっきりしました。その日の夜は森の音にして目を閉じると小鳥やふくろうの鳴き声が聴こえてきたので、どこにいるんだろうと歩き回っている気分になり気が付いたら、朝でした。今夜は何の音を聴いて寝ようかな?と眠る事が楽しくなりました。

### 5/5 — すごく眠れた

聞いて寝るだけですっきり起きれました。自然の音に癒されました。

### 5/5 — 心地良い

翌朝早く起きないといけないのに、なかなか寝つけない……という時に使ってみました。

ベッドに入ってからの時間が特別な癒やしの時間になります！
応援しています！

### 4/5 — 寝る時は手放せないアプリ

*2026-08-24*

睡眠学会歯科専門医が監修してるって聞いて購入してみました。色んな自然の音がストレスフリーで心地良いのもあるのですが、バイノーラルビート？といわれるものが恐らく快眠に落ちやすい周波らしく毎日爆睡です。にしかわデンタルクリニックの医院長が開発に携わってたらしくて睡眠時無呼吸症候群、いびき治療にも力を入れてる歯医者だから効果良いのは納得です。他にも色んなパターンのサウンド作ってほしいです！
