# MaintainX vs CertusAlert

The clearest difference is monetization model: CertusAlert at free against MaintainX's free with in-app purchases. MaintainX's advantage is ratings volume (5.8K vs 1) and iOS requirement (16.4 vs 26.5). On price, rating, update cadence and ads 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 — 4.9 for MaintainX against 5.0 for CertusAlert. That said, the two scores are not equally well evidenced: MaintainX has 5.8K ratings behind it against 1, so its average is the more settled of the two.

MaintainX ships an update weekly, CertusAlert every 10 days. The most recent releases landed on October 16, 2026 and September 25, 2026 respectively.
