Not sure about this app – Gemr: Collector App Review

I read the reviews on this app, some were good so I decided to download it. The first time I tried to use it to sell something it didn’t work! I tried to download pictures of the items I wanted to sell and NOTHING! Tried 3times and the pictures wouldn’t download. Not sure why! I don’t think I Am going to be able to use this app
