# String vs GBPN

The clearest difference is rating: GBPN at 4.4 against String's 3.5. GBPN also leads on monetization model (free vs free with in-app purchases) and iOS requirement (13.0 vs 15.0). String's advantage is review sentiment (69% vs 50%) and ratings volume (62 vs 5). On price, ads, in-app purchases and device support there is nothing between them.

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

GBPN holds the better App Store score, 4.4 against 3.5. That said, the two scores are not equally well evidenced: String has 62 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 69% of String's written reviews are positive against 50% of GBPN's, so the app with the better star average is not the one people write more warmly about.
