Verdict

The call

The clearest difference is rating: Sub at 4.4 against iBridge's 2.4. Sub also leads on update cadence (every 5 weeks vs every 5 months) and ratings volume (778 vs 70). iBridge's advantage is monetization model (free vs ad-supported) and iOS requirement (11.0 vs 15.5). On price, review sentiment, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Sub holds the better App Store score, 4.4 against 2.4. That said, the two scores are not equally well evidenced: Sub has 778 ratings behind it against 70, so its average is the more settled of the two. Written reviews complicate that: 20% of iBridge's written reviews are positive against 15% of Sub's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

iBridge ships an update every 5 months, Sub every 5 weeks. The most recent releases landed on September 22, 2026 and September 20, 2026 respectively.
