WORST APP EVER!! COMPLETELY DESTROYED THE SMS FUNCTION ON MY PHONE!!! I wanted to send something to all 1600 people in my iPhone so I got HitEmUp. First, they failed to mention you have to hit send for every single contact so it took me hours to do so despite HitEmUp . Second, it doesn't show up on your home page so it was INCREDIBLY difficult to delete. Third, it disabled my iMessage, which says it's on but it's not, I get a failed to send message on every text before it sends, IF it sends. Some don't. Videos won't send. I'm getting calls from people who are asking why I haven't responded to texts I never received, while sending me screenshots of the sent texts, which forces me to use WhatsApp for the people I KNOW I'm not receiving texts from. Others....I'll never know about, which is going to seriously affect my business. I'm going to Apple tomorrow to see if they can untangle this mess. If not, I'll have to use a May backup and lose 20 GB of data added between May and Sept. Yes, 20 GB. I run a business from my phone. WORST APP EVER. I have never, EVER had anything screw up my phone as badly as HitEmUp. I would have been better off if the developers had stolen my phone. At least then, $1200 would have fixed the problem without me losing 5 months of data. I'm Furious.
