# Timegrapher X vs Testify

The clearest difference is price: Testify at Free against Timegrapher X's $29.99. Testify also leads on rating (5.0 vs 4.2). Timegrapher X's advantage is ratings volume (23 vs 1) and iOS requirement (18.0 vs 26.0). On ads, in-app purchases, monetization model and device support there is nothing between them.

Testify is free to download; Timegrapher X costs $29.99 up front. Timegrapher X sells 1 one-off in-app purchase and Testify sells 1 in-app purchase, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Testify holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: Timegrapher X has 23 ratings behind it against 1, so its average is the more settled of the two.
