# UD Browser vs GRAPES

The clearest difference is rating: UD Browser at 5.0 against GRAPES's 3.0. UD Browser also leads on update cadence (every 5 days vs every 3 months). GRAPES's advantage is review sentiment (59% vs 50%) and iOS requirement (10.0 vs 15.0). On price, ratings volume, ads and in-app purchases there is nothing between them.

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

UD Browser holds the better App Store score, 5.0 against 3.0. Both are backed by a comparable volume of ratings — 1 and 1 respectively. Written reviews complicate that: 50% of UD Browser's written reviews are positive against 59% of GRAPES's, so the app with the better star average is not the one people write more warmly about.

UD Browser ships an update every 5 days, GRAPES every 3 months. The most recent releases landed on November 8, 2026 and November 2, 2026 respectively.
