Top quality!

SimplexFX is defintely the best FX quote/chart app in the store now! I especially love the split-chart, which is very useful (and I think other major finance app like Bloomberg or Yahoo Finance should include this function)

The graph in the app is also very easy to read. Really a top quality finance app (and it's free!). Quote updating speed is smooth (5 seconds as default) and portfolio section can be updated too!

Like other reviews said, if it can add more currencies in the future, will definitly become the no.1 FX app on iPhone! I know it may not happen too soon since this app is actually based on domestic Japanese users, but will still looking forward to the update in the future.

Thanks for the fast update. Looks like you guys do read what we're suggesting. Now, for the portfolio section, anyway you can let us change the currency value to what we want? Such as in dollars instead of yen. Also, would be great if instead of amount in 1000+, let us enter that in lot size, such as 0.01, 0.1, 1.21 etc... Also, a choice option between mini and standard account within the portfolio, since pip value is different bwtween them. Would also be great if upon entering those values we can also enter our TP and SL value, and then have all those information be transfer to the graph charts so that we can track it there too. Least but not least, charts also updates with price movement. Once all those features are added, you'll have one killer forex app, number one in my book. Thanks again.

I don't understand that no reviews have been written about this excellent app to access real time currencies and beautiful charts. I use it much more than others for accuracy and technical study. Keep the good job!
