### 5/5 — Make Social Networking Apps Great Again

*2026-04-24*

This is literally the best app I’ve ever seen in the history of the world since I was a baby.  I’m not even sure how Ive been able to social network without it.  I wonder if it would work for accurately directing people to a beach party at some unknown location off the Bush Hwy someday, just hypothetically speaking

### 5/5 — 💯Best App in the game rn

*2026-04-04*

I met my wife at an Opin event. This app gets you off of TikTok, going outside to amazing events and meeting people IRL. If you don’t have Opin downloaded, you’re missing out on some of life’s greatest adventures.

### 5/5 — What a great idea!

*2026-04-04*

Great app idea. Your fourth player cancels for pickleball? Have a basketball but looking for others to join and make a game of it? Playing live music at a local venue and want to spread the word? Send an Opin! What an easy and casual way to connect with people around town. Love it.

### 5/5 — Search Engine + Social Media = Social Search

*2026-04-03*

I needed this app 10 years ago.
