# Phone Checker vs Testify

The clearest difference is rating: Testify at 5.0 against Phone Checker's 4.0. Testify also leads on ads (none vs shown). Phone Checker's advantage is in-app purchases (none vs 1) and ratings volume (7 vs 1). On price and device support there is nothing between them.

Both are free to download. Testify sells 1 in-app purchase, starting at $1.99 per month. Phone Checker asks for nothing beyond the download.

Testify holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: Phone Checker has 7 ratings behind it against 1, so its average is the more settled of the two.
