## What is Lean Theory?

No lean muscle? No small talk.

Lean Theory is a lightweight personal journal for workouts, meals and body photos. Record your day at your own pace.

WORKOUTS
One tap records a workout. Undo it or add optional details whenever you want.

MEAL PHOTOS
Open the camera, take a photo and save your meal. Add multiple photos each day without choosing categories or counting calories.

BODY JOURNAL
Keep progress photos, compare two moments and optionally use an earlier photo as a framing guide. Export or share body photos using the system share sheet.

PRIVATE AND SIMPLE
No account, ads or analytics. Records stay on your device. Supports English and Simplified Chinese, with optional weekly photo reminders.

Please note: there is no cloud sync or full-data backup/export. Records are excluded from system backups and may be lost if you uninstall the app or lose your device. Export important body photos separately. Lean Theory is a personal journal, not medical advice or a promise of fitness results.
