# TTI Browser vs Diigo Browser

The clearest difference is rating: Diigo Browser at 4.5 against TTI Browser's 1.0. Diigo Browser also leads on update cadence (every 2 weeks vs every 10 months) and ratings volume (560 vs 1). TTI Browser's advantage is review sentiment (100% vs 59%) and iOS requirement (8.0 vs 16.0). 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.

Diigo Browser holds the better App Store score, 4.5 against 1.0. That said, the two scores are not equally well evidenced: Diigo Browser has 560 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of TTI Browser's written reviews are positive against 59% of Diigo Browser's, so the app with the better star average is not the one people write more warmly about.

TTI Browser ships an update every 10 months, Diigo Browser every 2 weeks. The most recent releases landed on September 20, 2026 and September 1, 2026 respectively.
