# Taro vs ReliaQuest GreyMatter

The clearest difference is rating: Taro at 4.9 against ReliaQuest GreyMatter's 4.6. Taro also leads on ratings volume (645 vs 31) and update cadence (weekly vs every 3 weeks). On price, review sentiment, 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.

Taro holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: Taro has 645 ratings behind it against 31, so its average is the more settled of the two. Written reviews complicate that: 85% of Taro's written reviews are positive against 92% of ReliaQuest GreyMatter's, so the app with the better star average is not the one people write more warmly about.

Taro ships an update weekly, ReliaQuest GreyMatter every 3 weeks. The most recent releases landed on October 23, 2026 and October 25, 2026 respectively.
