I signed up with AppInstitute in July of 2017. I read the reviews at that time which were all from 2016 and nothing less than a 5 star rating... so, I went ahead and purchased the annual white label package ($1400). Everything was good. Good communication, they set up my account and platform, EVERYTHING was awesome.
Fast forward two months (length it took me to build the app). I submitted my app for publishing on September 1st. 1 week later, they sent me an email saying that they are no longer publishing to Apple Store or Google Play, but instead they are now doing PWA's (Progressive Web Apps) which will be available at the end of September. So, they switched their business model and clients are supposed to be okay with that? Anyways, I waited to try out the PWA. Everything was good, until a link to buying gift certificates didn't work. It took them THREE weeks, THREE WEEKS to fix the link! Needless to say, I lost my very first app client because I wasn't able to perform. I asked for a refund multiple times. They refused to give even a partial refund for the months I haven't used. I strongly advise you NOT to sign up with this company no matter how good it looks. For under $100 I was able to get an awesome performing app published on Apple and google through Fiverr.
