# SublueGo vs PBIBS

The clearest difference is rating: PBIBS at 5.0 against SublueGo's 2.3. SublueGo's advantage is ads (none vs shown) and update cadence (every 2 months vs every 12 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

PBIBS holds the better App Store score, 5.0 against 2.3. That said, the two scores are not equally well evidenced: SublueGo has 16 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 13% of SublueGo's written reviews are positive against 0% of PBIBS's, so the app with the better star average is not the one people write more warmly about.

SublueGo ships an update every 2 months, PBIBS every 12 months. The most recent releases landed on September 9, 2026 and June 5, 2026 respectively.
