The clearest difference is monetization model: NaruTango at free against LockBox's free with in-app purchases. NaruTango also leads on iOS requirement (13.0 vs 15.0). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. NaruTango sells 6 one-off in-app purchases and LockBox sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
