The app won’t open – Running Slimkit - Lose Weight Review

Downloaded it in hopes of using it due to good reviews, but it won’t go past step 1. I click the next button no matter how many times it tells me there is no internet connection. I’m using my cell phone yes there is lol. I would like to use the app but this is not a good first impression. 6s plus user.
