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.

Also super easy to use and I had a question that Kai (the app developer) helped answer promptly over email! **Developer response:** Thank you for the review Amanda. I’m happy you find my app useful. Best, Kai ### 4/5 — Very quick and clear *2024-09-23* Will tell my friends **Developer response:** Thank you! If you like the app 5 stars would support me even more than 4 stars. But thank you for the review. I appreciate it. Best, Kai ### 5/5 — About *2024-05-01* Interesting **Developer response:** Thank you ### 5/5 — Day 1, so far so good 👌 Few months in, useful. *2024-01-07* Just setting this app up now, so far so good. Has already motivated me to call one person who has been waiting for me to reply. Makes it more manageable to just see a list of people I want to stay connected to, and to sort them in a way that helps me to make the next contact when I can. A few months in, it is useful especially given it’s a free app and doesn’t use any of your private data for their own profit. **Developer response:** Thank you! If you have feedback later on you can also contact me at kai@amicu.app ### 5/5 — Excellent way to remember to keep in touch *2023-12-29* Basically a social CRM that allows you to dictate how often the app should remind you to check in with family or friends **Developer response:** Thank you Cornelius ### 5/5 — THE app for keeping up with personal relationships *2021-07-06* Discovered this app from an online recommendation, and it fits my needs perfectly for reminders to maintain and cultivate my personal relationships. Highly recommended!! **Developer response:** 🙏 Thank you Brandon. ### 5/5 — Wonderful idea! *2021-04-06* It can be hard to stay connected these days, but Amicu makes it easy + fun. **Developer response:** Thank you for your review! Best, Kai ### 5/5 — Awesome app, amazing developer! *2021-02-21* I've been using this for about two weeks on a homescreen I have dedicated to keeping in touch with friends, events, birthdays, friend related to-do. This app hasbeen a great addition to this space. I contacted the developer with a suggestion, thinking it might eventually be implemented in a year or so — but he quickly replied with a sketch of the feature, and actually implemented it less than a week later. My mind was blown. Amazing support, and a super useful app that has a bright future ahead. Love it. **Developer response:** You’re welcome Travis. Best, Kai ### 5/5 — So important these days! *2021-02-12* Keeping up with everyone digitally is no easy task. This really takes a lot of the work out of the process and encourages me to be better about it. 👍 **Developer response:** Thank you for your review! Best, Kai ### 5/5 — Helpful app for staying in touch *2020-12-28* This has helped me prioritize my people I want to reach out to more and I feel better knowing I won’t lose anyone. **Developer response:** Thank you for your kind review! 🙂 ## Frequently asked questions about Contacts Address Book ### What does Amicu do?
