Digital Gifting, Reimagined

What it does

Not everyone has the key. HeartKey is a new way to send messages, memories, and surprises. Inside locked boxes that open only for someone who truly knows you. Create a box. Add your message, photo or video. Set your locks. Send the key challenge. They won’t see what’s inside until they answer your questions correctly. Perfect for couples, flirting, anniversaries, birthdays, surprises and long-distance relationships.

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
