# ThinkDiag+ vs Torque Pro

The clearest difference is review sentiment: ThinkDiag+ at 74% against Torque Pro's 6%. ThinkDiag+ also leads on in-app purchases (none vs 5) and ads (none vs shown). On price, update cadence and device support there is nothing between them.

Both are free to download. Torque Pro sells 5 in-app purchases, starting at $9.99 per 7 days. ThinkDiag+ asks for nothing beyond the download.

ThinkDiag+ holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: ThinkDiag+ has 4.3K ratings behind it against 520, so its average is the more settled of the two.
