Verdict
The clearest difference is rating: Lemen at 5.0 against ThinkByte's 4.1. Lemen also leads on iOS requirement (14.0 vs 17.0). ThinkByte's advantage is ratings volume (11 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. ThinkByte sells 1 one-off in-app purchase and Lemen sells 7 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.
Lemen holds the better App Store score, 5.0 against 4.1. That said, the two scores are not equally well evidenced: ThinkByte has 11 ratings behind it against 2, so its average is the more settled of the two.
