I've used Grindr on and off for about 10 years. While it does help you find guys, it has a lot of issues. Since there is no CAPTCHA when signing up, there is an absurd amount spam bots, I've had 10 in one day, but Grindr does not address the issue. Their premium features are ridiculously expensive and you get hammered with ads when you use the free version, half of which close your app when the finish playing. The issue is that there is no real competition against Grindr, so they won't improve.
