FAR/AIM is free to download; ATPL Dictionary costs $1.99 up front. FAR/AIM sells 1 one-off in-app purchase and ATPL Dictionary sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.7 for FAR/AIM against 4.7 for ATPL Dictionary.
