Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
TestApp.io holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: ReliaQuest GreyMatter has 31 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 91% of TestApp.io'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.
Both ship on a similar rhythm, roughly every 3 weeks. Both last shipped on October 25, 2026.
