Oki's advantage is ratings volume (387 vs 5). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Esential sells 1 in-app purchase, starting at $14.99 per month and Oki sells 10 in-app purchases, starting at $1.00 per month. Whichever you choose, the download price is not the number that matters.
