Retain Cards's advantage is ads (none vs shown) and ratings volume (422 vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Retain Cards sells 10 in-app purchases, starting at $12.99 per month and Etchd.ai sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
