# XRay vs Tech Aide

The clearest difference is review sentiment: Tech Aide at 100% against XRay's 33%. Tech Aide also leads on rating (5.0 vs 4.1) and update cadence (weekly vs monthly). XRay's advantage is ratings volume (135 vs 3). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. XRay sells 3 in-app purchases, starting at $3.99 per 7 days and Tech Aide sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Tech Aide holds the better App Store score, 5.0 against 4.1. That said, the two scores are not equally well evidenced: XRay has 135 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 33% of XRay's written reviews are positive against 100% of Tech Aide's.

XRay ships an update monthly, Tech Aide weekly. The most recent releases landed on November 8, 2026 and October 31, 2026 respectively.
