Phase: Cycle & Energy Planner

Phase writes you a personalized energy briefing every morning — on your phone, before your alarm, using Apple's on-device AI.

Your cycle, sleep, HRV, and workout data never leave this device. There is no server. There is no account. There never will be.

WAKE UP KNOWING WHAT TODAY TAKES

Every morning, Phase quietly reads the health data your iPhone and Apple Watch already collect. It runs that data through Apple's on-device Foundation Models AI and writes you a single 2-line briefing about today's energy, focus, and recovery — plus three concrete actions you can take to make the day land.

One glance at your Lock Screen and you already know what kind of day is ahead, before you even unlock the phone.

YOUR DAY, IN ONE OF FOUR PHASES

• Builder Day — Full capacity. Front-load the hardest work.
• Strategist Day — Sharp and patient. The day for the deep edit.
• Restorer Day — Protect bandwidth. Honor the recovery.
• Pioneer Day — Fresh start. Send the bold message.

PRIVACY IS THE WHOLE POINT

Phase uses Apple's Foundation Models framework — the on-device AI built into iOS 26 — so every prompt and every response stays on your device. Forever.

• No server. No account. No cloud sync.
• No analytics SDK. No tracking. No third-party telemetry.
• Your cycle data is excluded from iCloud Backup at the filesystem level.
• Phase only READS from Apple Health. It never writes back.
• Privacy Manifest declares zero data collection, zero tracking domains.

Cycle data is the most personal data on your phone. Phase treats it that way.
