If it works as good as it looks you've got yourself a keeper. I really like how you used a dark theme and lined out logo's etc. Looks very appealing to the eye. I would test the app if I had an ios device, which I don't. Are you planning on releasing something for android too in the near future? Did you do this by yourself?
Thanks for the feedback! Android is in the works, but as I am currently working on it all myself (a few different people/organizations have approached me about investing/partnering, but for now still solo on it), it might take me a few weeks. Will update you once its live!
