Secret Agent London is free to download; Lost Echo costs $4.49 up front. Neither carries in-app purchases, so what you see is what you pay.
Lost Echo holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: Lost Echo has 86 ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 76% of Lost Echo's written reviews are positive against 100% of Secret Agent London's, so the app with the better star average is not the one people write more warmly about.
