Verdict
The clearest difference is rating: Sub at 4.4 against SPAN Home's 3.6. Sub also leads on ratings volume (786 vs 104) and device support (3 vs 1). SPAN Home's advantage is review sentiment (29% vs 15%) and update cadence (fortnightly vs every 5 weeks). On price, 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. Neither carries in-app purchases, so what you see is what you pay.
Sub holds the better App Store score, 4.4 against 3.6. That said, the two scores are not equally well evidenced: Sub has 786 ratings behind it against 104, so its average is the more settled of the two. Written reviews complicate that: 15% of Sub's written reviews are positive against 29% of SPAN Home's, so the app with the better star average is not the one people write more warmly about.
Sub ships an update every 5 weeks, SPAN Home fortnightly. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
