# Ajusa Mobile vs ThinkDiag+

The clearest difference is review sentiment: ThinkDiag+ at 74% against Ajusa Mobile's 33%. ThinkDiag+ also leads on ratings volume (4.4K vs 1) and update cadence (every 3 weeks vs every 2 months). Ajusa Mobile's advantage is rating (5.0 vs 4.5) and monetization model (free vs free with in-app purchases). 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.

Ajusa Mobile holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: ThinkDiag+ has 4.4K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 33% of Ajusa Mobile's written reviews are positive against 74% of ThinkDiag+'s, so the app with the better star average is not the one people write more warmly about.

Ajusa Mobile ships an update every 2 months, ThinkDiag+ every 3 weeks. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
