When developing iOS apps, if you cannot hire a designer in your team, then you or someone else in your team should try and learn some basic design skills. In a market like the Apple App Store where there are a huge number of apps, the easiest way to differentiate yourself is with the help of good design.

You are going in the right direction though with the design. Best of luck.

Thank you! It's hard and costly to find a full-time and suitable designer. So a contract or part-time designer is a good idea.
