VisaDays app for iPhone and iPad

Remaining days calculator is a helping tool for travellers who want to keep track on days left to stay in specific region(e.g. EU) based on the rule "maximum X days stay in Y days period".
App calculates the length of previous and/or on-going stays and provides an answer whether the stay in a region complied/complies with the X days in Y days period rule as day of today. If the X days limit is not exceeded within the relevant Y days period reference period, the calculator indicates how many days left stating from today and which is the last day of stay when the X days in Y days period rule would still be respected taking in account future stays if any are planned.
In case the rule is not respected, the calculator provides the number of days exceeded in the Y reference period.
