About this app

Never forget anything again with letmeknow - the intelligent reminder app that understands natural language.

🤖 AI-POWERED INTELLIGENCE
Simply type or speak what you need to remember in your own words. Our AI automatically understands when and what you want to be reminded about.

Examples:
• "Meeting with John tomorrow at 3pm"
• "Buy milk on the way home"
• "Call mom this weekend"
• "Pay rent on the 1st of next month"

No more complicated date pickers or time selectors - just natural conversation.

✨ KEY FEATURES

📝 Natural Language Input
Type reminders the way you think. Our AI parses dates, times, and context automatically.

🎤 Voice Input (Premium)
Speak your reminders hands-free. Perfect for when you're driving or busy.

👥 Topics - NEW
Reminders track when. Topics track who. Jot a note after a conversation and it lands under the right person, so you can check what you last talked about before you meet again - and stop losing the book you promised to lend or the follow-up you owe. Search, tag and star the people you come back to most.

📱 Smart Notifications
Get reminded at exactly the right time with precise, reliable notifications.

📅 Calendar View
See all your upcoming reminders in a beautiful calendar interface.

✏️ Easy Editing
Long-press any reminder to quickly edit the time or description.

↔️ Swipe Actions
• Swipe right to complete
• Swipe left to delete

🌙 PREMIUM FEATURES

Upgrade to Premium and unlock:
• 🎤 Unlimited voice reminders
• 📝 Create multiple reminders at once
• 🌑 Dark theme
• 📲 Home screen widgets
• ☁️ Encrypted automatic backup

Your backup is encrypted on your device before it leaves it, with a passphrase only you know - so nobody else can read it, including us. That also means a forgotten passphrase cannot be recovered, so keep it somewhere safe. Restoring a backup is always free, even without Premium.

💡 SMART & INTUITIVE

Our AI understands various time expressions:
• "tomorrow afternoon"
• "next Monday at noon"
• "in 2 hours"
• "every Friday"

🔒 PRIVACY
Your reminders and notes live on your device. To turn what you write into a reminder, the text is sent to an AI provider to be processed - we don't store it on our servers, and the paid API tiers we use don't train on it. Cloud backup is optional and encrypted before it leaves your phone.

📱 CLEAN DESIGN
Beautiful, minimalist interface that gets out of your way and lets you focus on what matters.

🎯 PERFECT FOR
• Busy professionals
• Students managing assignments
• Parents juggling family schedules
• Anyone who wants to stay organized

📲 Download letmeknow today and never miss what matters.
AI-powered reminder app. Just say what you need - we'll handle the rest.
