Verdict
The clearest difference is review sentiment: Rules! at 69% against Jupiter Attack's 40%. Jupiter Attack's advantage is rating (4.5 vs 4.2) and chart position (#16 vs unranked). On update cadence, 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
Rules! costs $2.99 and Jupiter Attack $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Jupiter Attack holds the better App Store score, 4.5 against 4.2. That said, the two scores are not equally well evidenced: Jupiter Attack has 383 ratings behind it against 67, so its average is the more settled of the two. Written reviews complicate that: 69% of Rules!'s written reviews are positive against 40% of Jupiter Attack's, so the app with the better star average is not the one people write more warmly about.
Rules! ships an update monthly, Jupiter Attack every 2 months. The most recent releases landed on September 22, 2026 and September 25, 2026 respectively.
