Hey everyone! 👋 I’m Rodrigo, the maker behind Scheduler for WhatsApp. I’m thrilled to finally share this with the community today! Here is the backstory of why I built it, the problem I was trying to solve, and how it evolved into a native macOS app: 🎾 The Spark & The Problem It all started with a personal frustration. Every week, my local sports club opens court bookings at 8:00 AM sharp on WhatsApp. If you send your message at 8:00:03, you miss out; if you send it at 7:59:59, the admins reject it. I kept having to disrupt my morning routine just to hit "Send" at the exact second. When I looked for tools to solve this, I found that almost every existing solution had three huge dealbreakers: Privacy risks: They required connecting to third-party cloud servers that intercept and read your private chat sessions. The "Sleep" problem: If your MacBook closed or went into sleep mode overnight, scheduled messages simply wouldn't send. Predatory subscriptions: They charged $20–$40 every month for clunky marketing bots aimed at mass spam. 🛠️ How It Evolved I initially hacked together a rough local Python script just to solve my own booking problem. It worked like a charm, but soon friends and colleagues asked if they could use it for daily team standups, client reminders, and birthday messages. That’s when I decided to build a true, standalone macOS desktop app from the ground up: Hardware Auto-Wake (pmset): I integrated macOS RTC hardware programming so the Mac automatically powers on from sleep 2 minutes before the dispatch time. Sub-50ms Dispatch Engine: Re-engineered the input delivery using native macOS pasteboards and DOM hooks to achieve near-instantaneous execution. 100% On-Device & Zero Telemetry: Everything lives locally in your restricted user directory (~/.whatsapp_scheduler). No cloud backend, no message scraping, zero data tracking. Pay Once, Use Forever: I’m a firm believer that personal desktop utilities shouldn't be recurring subscriptions. It's a simple one-time purchase with free lifetime updates. 🎁 Try It Out You can test drive the full Pro version with a 7-day free trial (no credit card or account needed) right here: 👉 rockdrigoma.github.io I'd love to hear your thoughts, feedback, and feature requests!

What’s the #1 message you wish you didn't have to remember to send manually?

When designing Scheduler for WhatsApp, I built it to solve my own hyper-specific headache (grabbing sports court bookings at 8:00 AM sharp). Since then, early testers have used it for completely different workflows:

Daily Team Standups: Sending status bullets without waking up early across timezones.
Midnight Greetings: Celebrating birthdays and anniversaries right at 12:00 AM without staying awake.
Client Consultations: Scheduling non-intrusive reminder follow-ups for meetings.
Competitive Bookings: High-speed booking reservations where slots vanish in seconds.
