WhatsApp Scheduler: Offline-first, hands-free message scheduler for Android (30 Pro Codes Giveaway)

Hey makers & hunters!

I built WhatsApp Scheduler: Auto Sender for Android to solve client follow-ups and late-night message scheduling without waking people up or relying on expensive cloud CRM subscriptions.

Key architecture & features:

• 100% Offline-First: Room/SQLite database stored locally on device. No contacts or message content ever touch an external server.

• Hands-Free Dispatch: Dispatches automatically at scheduled times via AccessibilityService node traversal for personal 1-on-1 chats.

• Exact Alarm Synchronization: AlarmManager exact scheduling with custom battery optimization health diagnostics for Android 13/14+.

• Supports photo & picture scheduling with custom captions.

• Pre-saved Quick Templates + custom template creator.
