# GrapeData vs ISC

The clearest difference is rating: ISC at 4.5 against GrapeData's 3.5. GrapeData's advantage is ads (none vs shown) and review sentiment (54% vs 36%). On price, in-app purchases, monetization model 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.

ISC holds the better App Store score, 4.5 against 3.5. Both are backed by a comparable volume of ratings — 111 and 30 respectively. Written reviews complicate that: 54% of GrapeData's written reviews are positive against 36% of ISC's, so the app with the better star average is not the one people write more warmly about.

GrapeData ships an update fortnightly, ISC every 2 months. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
