TravelTill app for iPhone and iPad

TravelTill is a specialized calculator, optimized for performing calculations typical for retail sales quickly and with little effort.

It easily lets you add the prices of various items together, apply individual or global discounts, and calculates sales taxes at every step. TravelTill also supports cent-rounding to the nearest 5, 10 or 50 cents as well as the nearest dollar (or equivalent) for jurisdictions where smaller coins have been abolished. TravelTill supports four rounding modes: round half up (round 1-4 down and 5-9 up), round half down (round 1-5 down and 6-9 up), always round down, always round up. TravelTill is also able to calculate change due — again rounding the calculation as desired.
