Verdict
The clearest difference is ads: Double Good at none against Sphinx Hub's shown. Double Good also leads on update cadence (every 3 days vs every 6 months) and rating (4.9 vs 4.5). Sphinx Hub's advantage is review sentiment (100% vs 90%). On price, in-app purchases, device support and iOS requirement 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. Neither carries in-app purchases, so what you see is what you pay.
Double Good holds the better App Store score, 4.9 against 4.5. That said, the two scores are not equally well evidenced: Double Good has 44K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 90% of Double Good's written reviews are positive against 100% of Sphinx Hub's, so the app with the better star average is not the one people write more warmly about.
Double Good ships an update every 3 days, Sphinx Hub every 6 months. The most recent releases landed on September 25, 2026 and September 20, 2026 respectively.
