# MillerTech vs TempPro

MillerTech and TempPro both sit at 4.3 stars, but that hides the real split: 100% of MillerTech's written reviews are positive against 2% of TempPro's. TempPro's advantage is ratings volume (533 vs 6) and update cadence (every 3 weeks vs every 2 months). On price, rating, ads and in-app purchases there is nothing between them.

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

On the App Store both sit at effectively the same score — 4.3 for MillerTech against 4.2 for TempPro. That said, the two scores are not equally well evidenced: TempPro has 533 ratings behind it against 6, so its average is the more settled of the two.
