# Infocar vs ThinkDiag+

The clearest difference is in-app purchases: ThinkDiag+ at none against Infocar's 12. ThinkDiag+ also leads on ratings volume (4.4K vs 286) and iOS requirement (12.0 vs 14.0). On price, rating, review sentiment and update cadence there is nothing between them.

Both are free to download. Infocar sells 12 in-app purchases, starting at $3.99 per 3 months. ThinkDiag+ asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.5 for Infocar against 4.5 for ThinkDiag+. That said, the two scores are not equally well evidenced: ThinkDiag+ has 4.4K ratings behind it against 286, so its average is the more settled of the two. Written reviews are what separate them: 71% of Infocar's written reviews are positive against 74% of ThinkDiag+'s.

Both ship on a similar rhythm, roughly every 3 weeks. Both last shipped on October 26, 2026.
