I tried various friend-making apps.

At first, I wanted to make friends of the opposite sex, but there are many apps limited to women.
Favomatch is specialized in finding friends for supporting your favorite idols, so it's interesting that you can talk with others who support the same idol.
Touch is said to be safe with 24-hour monitoring, and since identity verification is mandatory, there are probably few weird people.
I've heard that Dote Match is also easy to use among women.
However, if you want friends of the opposite sex, Bumble might be better.
You can narrow down to friends with BFF mode, and the male fee is also cheaper.
Tantan has over 300 million users worldwide, so the range of encounters is broad, but the search function is a bit too simple.
For people in their 30s and 40s, Somli might be an option.
In the end, I felt that the app you choose depends on your purpose.
If you want friends of the opposite sex, an app that allows same-sex search;
if same-sex friends, specialized apps like Favomatch.
If safety is a priority, apps like Touch with 24-hour monitoring.
If you want to try for free, Tinder or Bumble are good options.
Choosing the right app is surprisingly important.
