Introvert's advantage is ratings volume (890 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Introvert sells 10 in-app purchases, starting at $6.99 per month and Grammobolica sells 5 in-app purchases, starting at $1.99 per 7 days. Whichever you choose, the download price is not the number that matters.
