# WaterGuru vs Minoston

The clearest difference is review sentiment: WaterGuru at 74% against Minoston's 25%. WaterGuru also leads on update cadence (every 4 weeks vs every 9 months) and ratings volume (239 vs 66). Minoston's advantage is rating (4.5 vs 4.1) and iOS requirement (11.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.

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

Minoston holds the better App Store score, 4.5 against 4.1. Both are backed by a comparable volume of ratings — 239 and 66 respectively. Written reviews complicate that: 74% of WaterGuru's written reviews are positive against 25% of Minoston's, so the app with the better star average is not the one people write more warmly about.

WaterGuru ships an update every 4 weeks, Minoston every 9 months. The most recent releases landed on November 11, 2026 and November 3, 2026 respectively.
