Do not download

Be careful with this app. After one day of using this I started getting spam on my phone popping up only when I opened the app. Ads about naked pix and would only give me an option for ok so I had to keep shutting the app. It seems to me that thumb is not a safe app anymore. It use to be better over a yr ago now I come back to find it has changed for the worse. I don't want to risk messing up my phone so I'm staying off this horrible app. There's also lots of pervs and children on it. Children and teens asking to rate them. People with fake profiles. Men of all ages trying to talk and flirt with anything and anyone. Questions are not interesting at all, they all consist of something sexual now. I think they should shut down this app if they're not going to do a better job at making it better. Do not let your kids download this, or your wife or husband or anyone you care about because not only is it dangerous but I believe it's not safe for your computer or phone.

Thumbs up

Reading all these complaints I figured I should add my opinion (since that's what Thumb is about). First, for everyone complaining about kik and sex pics and whatnot, you can unclick the selfie category, problem solved. While I didn't have the app when it was Opinionaided, I really enjoy what Thumb is now. The hashtags are new and I use them to ask q's to different groups of people about certain topics. To me Thumb is addicting, I love helping people through the app by answering questions or chatting with them

Thumb has turned to crap.

I've had this app on and off for a few years, and I'll admit I used to love it but now every post is exactly the same. Even when the category you're in has nothing to do with it, all you see is selfies of 12 year old girls asking if they're pretty, and desperate guys asking for kik. If you're into that, then go for it and download this app. I understand this app is meant for you to get opinions, but it gets annoying when you see the same thing over and over. I would NOT recommend downloading this app if you're looking for genuine advice because most people either thumb down/move on to the next post or give crappy advice.
