Repair this app
There is a lot to fix in this shitty app.
Make it easier to give feedback, now it is impossible for users without a separate account for this service, and the creation of this account seems like an obstacle course. Do you not want feedback? Or perhaps can not handle it? Sure way to lose your leading position in the market.
Your "moderation" is a joke. This app is full of hookers and hustlers, and reporting them usually just instantly creates perhaps a bot-answer that says there is nothing wrong, and no actions will be taken. The behavior of users here is getting worse, and you seem to not care.
It should not be possible to create another account to the same contact-info if one gets kicked out. A ban of some sort would be required, otherwise the same hookers and hustlers just come back harassing normal users.
It should not be possible to create a profile without ANY pic. A screen full of black boxes is really dull and makes searching just uninviting.
I will never pay for the app that is for sure. No matter how bad you try to make the experience. I will just stop when it comes unbearable. I would not mind ads, but now they work so bad that I am really close to quitting. Why are you so mean, that upcoming ad cuts of a user while writing a message?!
Do not publish untested updates. Every update has created more problems, and usually some of the old ones are not fixed. Could have something to do with the lack of interest on any feedback. You do ask often if I am enjoying using Grindr, but when I answer "no", you do not want to know why. That is just stupid.
Your basic function is easily copied and improved, but you seem to focus on cashing in - you should be really worried. I for one am looking for a replacement - might delete the account even without any.
