I was getting annoyed with how long the Coinbase app was taking to load so I decided to make my own fast loading live ticker using their data. I have been consistently getting load times (app open to price connection) around 250ms. Additionally, the app looks for an updated price every 5ms so you are getting the latest info. I have tested this against most of the major platforms and I am confident that this is the fastest on the app store.

​

I am a college student and can't be risking my meagre bitcoin holdings day trading so I built in a light-weight trading simulator with short selling, leverage and leaderboards. Right now it is iOS only, but if there is interest I will make an Android version. If you have any feedback or feature requests leave a comment!

It's called Bitcoin Simulator on the iOS app store:

Here is a vid showing just how fast it opens and connects to the price feed!
