UniCal - Calendar Converter

Nice app, but do you mind reducing the frequency of fullscreen video advertisements while introducing banner advertisements as replacements?

Like I it says

All the Roman numerals for years are wrong on the selector, eg the current year 221 shows CCXX, although on the iPhone, but not iPad, the year is also correctly shown next to the picture. It starts in 1792 as "Yr (1) / Yr I (2) / Yr II (3)…" Also, it does not say why I should pay $1.99 for the "complete version". I like the notifications, although for some reason you can't get them before 9 am, which is late for me. Some similar apps stop after 1805. The dates are calculated according to the fixed rule that leap days are added before (not after) years divisible by 4, which some may prefer, although the legal rule was to start years on the autumnal equinox.
