# mRay vs MRI

The clearest difference is review sentiment: mRay at 100% against MRI's 50%. mRay also leads on ads (none vs shown) and update cadence (every 2 months vs every 7 months). MRI's advantage is rating (4.0 vs 3.8) and iOS requirement (12.0 vs 15.0). On price, ratings volume, in-app purchases 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.

MRI holds the better App Store score, 4.0 against 3.8. Both are backed by a comparable volume of ratings — 4 and 10 respectively. Written reviews complicate that: 100% of mRay's written reviews are positive against 50% of MRI's, so the app with the better star average is not the one people write more warmly about.

mRay ships an update every 2 months, MRI every 7 months. The most recent releases landed on October 23, 2026 and October 31, 2026 respectively.
