Verdict

The call

The clearest difference is rating: Messana at 5.0 against Watts® Home's 4.6. Messana also leads on update cadence (every 3 weeks vs every 3 months). Watts® Home's advantage is review sentiment (27% vs 0%) and ratings volume (3.7K vs 3). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Messana holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Watts® Home has 3.7K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 0% of Messana's written reviews are positive against 27% of Watts® Home's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Messana ships an update every 3 weeks, Watts® Home every 3 months. The most recent releases landed on August 27, 2026 and September 22, 2026 respectively.
