Verdict
The clearest difference is rating: Challenges Aid at 4.1 against Water's 3.5. Challenges Aid also leads on monetization model (freemium vs subscription). Water's advantage is review sentiment (39% vs 30%) and ratings volume (23 vs 7). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Water sells 5 in-app purchases, starting at $0.99 per month and Challenges Aid sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
Challenges Aid holds the better App Store score, 4.1 against 3.5. Both are backed by a comparable volume of ratings — 23 and 7 respectively. Written reviews complicate that: 39% of Water's written reviews are positive against 30% of Challenges Aid's, so the app with the better star average is not the one people write more warmly about.
Water ships an update every 3 weeks, Challenges Aid fortnightly. The most recent releases landed on October 16, 2026 and October 1, 2026 respectively.
