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.

ReceptionRating · Positive reviews · Number of ratings

EBF Contacts holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Contacts Address Book has 53 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Contacts Address Book's written reviews are positive against 50% of EBF Contacts's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Contacts Address Book ships an update every 4 weeks, EBF Contacts every 6 weeks. The most recent releases landed on October 29, 2026 and October 24, 2026 respectively.
