Verdict
The clearest difference is ratings volume: Ripples at 235 against 66 Challenge's 5. 66 Challenge's advantage is rating (5.0 vs 4.7) and update cadence (every 5 days vs fortnightly). On price, ads, in-app purchases and monetization model 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. Ripples sells 5 in-app purchases, starting at $2.99 per month and 66 Challenge sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
66 Challenge holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Ripples has 235 ratings behind it against 5, so its average is the more settled of the two.
Ripples ships an update fortnightly, 66 Challenge every 5 days. The most recent releases landed on October 25, 2026 and October 5, 2026 respectively.
