Why Two Separate Apps ?
A survey of customers discovered they have a preference for two separate apps, a paid pro version and a free version rather than a free download with a pro upgrade as an In App Purchase.
The Free version contains some third party commercial advertising, these ads do not appear in the Pro version.
In the Free version you can view historic charts for any currency pair for 1 month and 3 months. Additional charts for 1 year, 3 years and 10 years are availabe to users of the Pro version.
You can build a list of your favourite currency pairs and see the current exchange rates for them all on one page. The Free version permits you to have up to four items in the Watch List, the Pro version is unlimited.
Thanks and have a great day
