# PRO vs DryLINK

The clearest difference is review sentiment: DryLINK at 100% against PRO's 30%. DryLINK also leads on device support (3 vs 1) and iOS requirement (13.0 vs 16.0). PRO's advantage is rating (4.9 vs 4.1) and update cadence (every 2 weeks vs every 3 months). On price, ads, in-app purchases and monetization model there is nothing between them.

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

PRO holds the better App Store score, 4.9 against 4.1. That said, the two scores are not equally well evidenced: PRO has 111 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 30% of PRO's written reviews are positive against 100% of DryLINK's, so the app with the better star average is not the one people write more warmly about.

PRO ships an update every 2 weeks, DryLINK every 3 months. Both last shipped on November 2, 2026.
