Aviation Dictionary's advantage is monetization model (free with in-app purchases vs subscription). On price, in-app purchases and device support there is nothing between them.

Both are free to download. World Clock Pro sells 5 in-app purchases, starting at $1.99 per month and Aviation Dictionary sells 3 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.
