# 타임스프레드 vs Certpia

타임스프레드 and Certpia both sit at 4.6 stars, but that hides the real split: 61% of 타임스프레드's written reviews are positive against 13% of Certpia's. 타임스프레드 also leads on ratings volume (346 vs 37). Certpia's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

That said, the two scores are not equally well evidenced: 타임스프레드 has 346 ratings behind it against 37, so its average is the more settled of the two.
