Sleep is a skill. We coach it.

EMBER is a personal rest coach for iPhone. It turns sleep data, calendar events, daily rhythm, local weather, and bedroom conditions into one clear, personalized plan for tonight.

What EMBER does

• Builds a nightly plan with wind-down, lights-out, and wake times.
• Reads sleep and activity signals from Apple Health with read-only access.
• Adapts around early meetings, late events, travel, sunrise, and temperature.
• Provides a streaming AI Rest Coach grounded in the user's own plan.
• Includes rule-based coaching when no AI provider is configured.
• Supports Sleep Window Training, CBT-I-inspired sleep efficiency, and Thermal Wind-Down protocols.
• Schedules wake alarms and wind-down reminders.
• Turns a spoken mind dump into editable text.
• Adds social motivation through Box Space, friends, points, rewards, and collectible Blue Box skins.

Product experience

Tonight

One plan that explains what to do next and why it changed.

Agenda and Daily Rhythm

Calendar events are placed against a personalized circadian energy curve. EMBER can move the plan before an early start or a late night causes disruption.

Rest Coach

The coach combines the current plan, sleep trends, calendar context, and evidence-based guidance. Responses can stream from an OpenAI-compatible endpoint through OpenRouter.

Rest Lab

Sleep Window Training and Thermal Wind-Down turn sleep science into small, trackable actions.

Box Space

Healthy routines earn sleep points and unlock Blue Box skins. Supabase powers accounts, friendships, requests, rewards, and leaderboards.

Run the iOS app

Requirements:

• macOS with Xcode 16 or newer recommended
• iOS 17.6 deployment target
• A physical iPhone is recommended for HealthKit, location, microphone, and notification testing

Open the committed project:

open Ember.xcodeproj

In Xcode, select your development team and a unique bundle identifier, then build the Ember target.

To regenerate the project after changing project.yml:

brew install xcodegen
xcodegen generate

AlarmKit wake alarms are enabled when built with an SDK that provides AlarmKit and run on iOS 26.1 or later. Other reminder features remain available on the main deployment target.

Optional AI setup

Open EMBER Settings and enter an OpenRouter API key. The key is stored in the iOS Keychain. The model and OpenAI-compatible base URL can be changed in the app. Without a key, the rule-based Rest Coach remains available.

Run the official website

Production: https://ember-sleep.vercel.app/

cd official-website
pnpm install
pnpm dev

Open http://localhost:3000.

For Vercel, import this Git repository and set the Root Directory to official-website. The included vercel.json supplies the install and build commands.

Run the product film

cd video
npm install
npm start

Render the final video with npm run build.

Product copy

Sleep is a skill. We coach it.

A tracker tells you about last night. EMBER tells you what to do tonight.

Your signals. One clear recommendation.

Evidence in. Better nights out.

Privacy and scope

Apple Health access is read-only. Raw sleep and recovery data is processed on the device; social account and Box Space data use Supabase. EMBER is a wellness tool, not a medical device, and does not diagnose or treat sleep disorders.
