# HMI Editor vs Wastewater Map

The clearest difference is in-app purchases: Wastewater Map at none against HMI Editor's 3. Wastewater Map also leads on review sentiment (100% vs 75%) and rating (5.0 vs 4.7). HMI Editor's advantage is ratings volume (10 vs 1) and device support (4 vs 1). On price, update cadence and ads there is nothing between them.

Both are free to download. HMI Editor sells 3 one-off in-app purchases. Wastewater Map asks for nothing beyond the download.

Wastewater Map holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: HMI Editor has 10 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 75% of HMI Editor's written reviews are positive against 100% of Wastewater Map's.

HMI Editor ships an update every 2 months, Wastewater Map every 3 months. The most recent releases landed on September 14, 2026 and October 24, 2026 respectively.
