# Sub vs D1® SpaIQ

The clearest difference is rating: Sub at 4.4 against D1® SpaIQ's 1.0. Sub also leads on ratings volume (786 vs 1). D1® SpaIQ's advantage is review sentiment (50% vs 15%) and monetization model (free vs ad-supported). On price, update cadence, ads and in-app purchases there is nothing between them.

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 1.0. That said, the two scores are not equally well evidenced: Sub has 786 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 15% of Sub's written reviews are positive against 50% of D1® SpaIQ'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, D1® SpaIQ every 2 months. The most recent releases landed on October 29, 2026 and October 20, 2026 respectively.
