Since the time-change, I have been rather off in calculating when I should say minchah. Is there an app which has an alarm for sh'kiya (or secular sundown timing if they differ) which is available for iOS?

Ultimate Zmanim for iOS has that feature.
With Zmanim Alarms, Ultimate Zmanim can remind you of important zmanim throughout the day. Shema, Tefila, and weekly candle lighting are all covered.
(To forewarn the question, on Android, Halachic Times is an equivalent).
