# SinoTrack PRO vs ThinkDiag+

The clearest difference is review sentiment: ThinkDiag+ at 74% against SinoTrack PRO's 22%. ThinkDiag+ also leads on rating (4.5 vs 2.9) and ratings volume (4.3K vs 47). SinoTrack PRO's advantage is monetization model (free vs free with in-app purchases) and iOS requirement (9.3 vs 12.0). On price, ads, in-app purchases and device support there is nothing between them.

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

ThinkDiag+ holds the better App Store score, 4.5 against 2.9. That said, the two scores are not equally well evidenced: ThinkDiag+ has 4.3K ratings behind it against 47, so its average is the more settled of the two. Written reviews point the same way: 22% of SinoTrack PRO's written reviews are positive against 74% of ThinkDiag+'s.
