Long time Reconnect with someone from your memories through AI Is there someone who suddenly comes to mind? Your first love, a childhood friend you used to play with, a neighbor you lost touch with after moving away, a fellow soldier you served with, or a precious connection that faded over time. Long time is an AI matching service that helps you find people you have long lost touch with, using clues hidden in your memories. Enter memories such as the school you attended together, the neighborhood you lived in, memorable events, meaningful places, or stories from that time. AI analyzes shared details across those memories and connects people who may be looking for each other. ■ Special Features of Long time [AI Deep Sync Matching] AI analyzes your memories and experiences to find people with a strong connection to you. By deeply reasoning through all the memories you provide, it recommends possible matches. [AI Standard Matching] Based on shared places, keywords, or fragments of memory, AI quickly and simply recommends people who may be connected to you. Designed with privacy as a top priority. Connections are only made when a mutual match is confirmed. ■ Recommended For • Anyone who suddenly thinks of their first love • Anyone who wants to find a friend they lost touch with • Anyone who wants to reconnect with childhood memories • Anyone looking for an old comrade • Anyone who wants to reconnect with a precious bond from the past • Anyone brave enough to reach out to a connection that once passed them by ■ Memories may fade, but connections remain Every day, we meet and part ways with countless people. But some connections stay in our hearts, even as time passes. Long time gathers those pieces of memory and helps people find their way back to each other. The person in your memories may still be looking for you, too. Reconnect with them through Long time. And when you finally find that person, try saying: “Long time. How have you been?”

Verdict

The call

The clearest difference is in-app purchases: DoSo at none against Long time's 3. DoSo also leads on iOS requirement (10.0 vs 15). Long time's advantage is update cadence (every 6 days vs every 3 weeks). On price, ads and device support there is nothing between them.
