Reminders to keep in touch and remember birthdays. Close personal relationships make life happier, healthier and longer. STORY: Hey everyone, I'm Kai - the guy behind Amicu. It’s great to catch up with someone you care about. But it's not so easy anymore. Your contacts are spread over many places. Mixed with people you don’t know. An avalanche of comments, posts, and texts cluttering everything up. It feels like a chore. No time for the joy of meeting up. And life changes. You move to new places. You change jobs. You travel and meet people, but they're abroad. You join events with cool people. But months of work follow. They stop to appear in feeds and inboxes. Instead of fun reunites relationships fade. I met people, while traveling, living abroad, and volunteering. Not all are on social media. Plus, who likes the distractions, ads, and privacy issues? So I made Amicu. It reminds you to catch up. You decide which people matter. After time reminders show up. Then it's your turn. Meet, call, or be creative. And your contacts should be no one’s business. With Amicu nothing leaves your device. That's it. No spam, privacy-invasion, customer relationships, or feeds. Simple and easy.
