# DailyHack vs 66 Challenge

The clearest difference is ads: 66 Challenge at none against DailyHack's shown. 66 Challenge also leads on rating (5.0 vs 4.8) and iOS requirement (13.0 vs 17.0). DailyHack's advantage is ratings volume (104 vs 5). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. DailyHack sells 5 in-app purchases, starting at $1.99 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 4.8. That said, the two scores are not equally well evidenced: DailyHack has 104 ratings behind it against 5, so its average is the more settled of the two.

DailyHack ships an update every 3 days, 66 Challenge every 5 days. The most recent releases landed on September 22, 2026 and September 4, 2026 respectively.
