There are a couple of reasons why Tinder might be crashing on you, here are the top 3 problems people have with the Tinder app:
1) The first thing to check is that you are up to date.
Make sure you are running the latest operating system for your phone, and also that you have the most recent version of Tinder installed on your phone (you can check the app store to see if there are any updates for Tinder waiting to be downloaded).
2) One thing I find interesting is that almost ALL problems with Tinder crashing are on iPhones. That is because there are a few iOS bgs floating around that might be forcing your applications to stall or quit unexpectedly.

3) There are also a handful of bugs that sometimes cause Tinder to freeze. I won't list them all, but you can find more details here:
