Teste de velocidade

I am looking to hire a freelancer to create a speed test application for me. The type of speed test I'm requesting is an internet speed test. I need a mobile app version of the test and am not sure if I need a feature that allows users to compare previous and current results. The right freelancer for this job will have experience creating speed test applications for mobile platforms. This job requires research expertise as well as development experience. I would like an application that is visually appealing, accurate, and user friendly. I am open to hearing the freelancer's ideas on how best to approach this project.
